Aug 4, 2017 | Education

New Site EclipseAmerica.Org Helps Elementary Teachers Get Ready for the EclipseSan Francisco - August 3, 2017 -- Mystery Science, creator of the fastest growing elementary science curriculum in America, and Google (NASDAQ: GOOG, GOOGL) today announced they are working together to help millions of children across the U.S. experience the Great American Total Solar Eclipse on August 21, 2017. Millions of solar eclipse glasses are being distributed to community libraries in the STAR Library Education Network to be given away free of charge, thanks in part to the support of Google. In addition, Google has provided Mystery Science with fifteen thousand eclipse glasses to be shipped directly to schools. Mystery Science is getting eclipse glasses into the hands of elementary teachers as well as providing exclusive educational videos and lesson plans, available for free download today at EclipseAmerica.org.“Going to the moon, exploring the surface of mars, or seeing a total solar eclipse across the US for the first time in a century are amazing moments that can inspire a whole new generation of explorers and scientists," said Calvin Johnson, Program Manager at Google for the Eclipse Megamovie project. "Our collaboration with Mystery Science ensures that educators have the resources needed to drive and encourage the curiosity of students and push our understanding of the universe to another level.”In the last year, over 1 million children experienced Mystery Science in their elementary schools, leveraging its open-and-go curriculum.“Those who have been fortunate enough to experience a total solar eclipse usually describe it as a ‘moment of awe’,” said Keith Schacht, co-founder and CEO of Mystery Science. “The next Marie Curie or Albert Einstein is somewhere out there right now. Experiencing this eclipse might be a singular event that inspires a lifetime of curiosity.”Why You Should Care About the Solar Eclipse
  • The August 21 event happening across the U.S. from Oregon to South Carolina is a once-in-a-lifetime moment for many. The sky will go dark, the air will cool, crickets will chirp, and stars will become visible in daytime.
  • The last time a total solar eclipse crossed the United States was in 1918, nearly one hundred years ago. In historical perspective for most young adults, it means most of their parents and grandparents have never seen a solar eclipse.
  • In this modern era, where children spend so much time indoors and on digital devices, this is an opportunity to inspire them with one of the greatest wonders in the natural world. The solar eclipse provides a unique way to get them excited through a real world experience.
  • The next total solar eclipse to cross the United States like this one won't occur until the year 2045. So don’t miss the 2017 eclipse, as this one might be your only chance.
  • It is extremely dangerous to ever look directly at the sun. This is why specially designed safety glasses are needed.
Unique Solar Eclipse Info on EclipseAmerica.org
  • Explanation video made for kids. Mystery Science creates engaging content that children love. Too often, scientific explanations are heavy on dry vocabulary and technical details rather than engaging content.
  • What time the eclipse will be in your city. Mystery Science knows that where you are physically on August 21 will dramatically alter your experience with the eclipse. So, they created a helpful Eclipse Time Checker where a person can type in their city and it will tell them when exactly to look.
  • Everything a teacher needs. Mystery Science created an open-and-go eclipse lesson. Mystery Science is used in 10% of elementary schools in the U.S. and understands what teachers will need to help their students experience this moment of awe.
Google’s Solar Eclipse Branded Glasses on Par with NASA StandardsAccording to NASA, homemade filters or sunglasses of any kind are not safe for looking at the sun during this solar eclipse. These Google solar eclipse glasses meet NASA’s standards and have extremely dark lenses as they were made by Rainbow Symphony. The Sun or eclipse should not be viewed with an unfiltered camera, telescope or binocular as it will result in serious injury to your eyes.Pricing and AvailabilityInterested teachers in the U.S. can go to the EclipseAmerica.org today to request their free solar eclipse glasses from a local library or to be shipped directly to their school.

The Truth About Climate Change

Jun 5, 2017 | Culture

By Andrew BernsteinClimate change is real and persistent. Even a brief study of the recent past illustrates this, but it becomes all the more certain when one broadens the scope to take in the vast sweep of geologic time. Is nature’s inherent dynamism responsible for the climate change of our era? Or are the cause(s) man-made? Many scientists, environmentalists, journalists, and such politicians as Al Gore claim the latter.They argue that:
  1. The earth is warming.
  2. Human emission of such greenhouse gases as CO2 is the predominant (perhaps exclusive) cause.
  3. Such warming, in various forms, is pernicious to life on Earth, including human life; for example, increasing temperatures may melt the land-based polar ice caps, thereby causing rising sea levels that will flood low-lying coastal regions.
This is known as the theory of man-made or anthropogenic global warming (the AGW hypothesis). The public policy questions that arise are profound, and the stakes are high; for if the AGW hypothesis is true, then we aren’t doing enough to protect ourselves from baneful consequences.But if  the AGW hypothesis is mistaken regarding either points two or three—much less both—then a dramatic scale-back of man-made carbon emissions is an insane policy that will severely diminish human living standards while promoting no off-setting gain.The Intergovernmental Panel on Climate Change (IPCC)—a group of scientists under United Nations jurisdiction—supports the AGW hypothesis. Its proposed solution is a dramatic increase in government power to impose massive scale-backs in the use of carbon based fuels.  Such a policy would affect the price and availability of literally everything we own: our clothes, home, food, medicine, and means of transportation. Energy powers civilization; the less of it produced, the more difficult and poverty-ridden life becomes.Needlessly diminishing carbon-based energy production without a viable alternative will have drastic consequences in the developed world. But more harrowing, it will mean certain death for millions of people in the undeveloped world. The first point to be established, therefore, is whether, in fact, there is any rational basis for accepting the AGW hypothesis. Doing so requires an understanding of Earth’s climate history viewed in the proper context, meaning in this case, on an appropriate timescale.  Earth’s Climate Over Geologic Time Charts are a common part of contemporary climate change debate. It is frighteningly common to see charts that graph out as much as the last 150 or so years of climate history. During that time, the Earth, on average, warmed roughly 2.16 degrees Fahrenheit (approximately 1.2 degrees Celsius). Our era, consequently, is known as the Modern Warm Period. This truth is widely acknowledged by scientists.Those that refuse to evaluate climate change on the proper timescale present this as a fair sample of the Earth’s climate trajectory. Given the human life expectancy, there is even some plausibility to such a narrow time frame. That is, until we are reminded that the Earth is approximately 4.5 billion years old. That puts the sample  examined at a nanoscale percentage of Earth’s climate history. It is like straining to read a billboard when able to view but a single pixel of it.What AGW theorists fail to mention is that the Earth in our day is significantly colder than it has been through much of its voluminous history. For the past 50 or so million years, the Earth has been gradually cooling. Prior to that, our planet had been substantially warmer. Fossil remains of tropical flora and fauna, for example, have been found north of the Arctic circle, and crocodiles lived in these northern climes.[1] It was around 30 or 35 million years ago that global temperatures dropped sharply, leading first to Antarctic glaciation, then (millions of years later) to Arctic ice sheets, and eventually to the Pleistocene Ice Age, including the most recent wave of Northern Hemisphere glaciation. Before then, Earth’s vast history—although interspersed with severe ice ages—featured climates generally warmer than today’s. Geologist, Dr. Doug Macdougall, notes, “On average, for the past few million years, the Earth has been considerably colder than over most of its four and a half billion years of existence.”[2]Indeed, the geology professor points out that, “During much of Earth history, except for short, rare intervals, glaciers such as the one on [Mount] Kilimanjaro have been absent.”[3] Does this mean that for much of Earth’s vast history the planet has been too warm for substantial accumulations of ice? Evidently it does.If ice ages are unusual features of Earth’s history, such rarity does not mitigate their severity. One such extreme episode, nicknamed “Snowball Earth,” occurred between 800 million and 600 million years ago, featuring at least two and possibly four or five recurring waves of ice ages so severe that the entire planet, pole to pole, including the tropics, perhaps even the oceans, were heavily glaciated.[4]By 540 million years ago, the Earth had transformed from a giant snowball (or slushball, as some scientists prefer) to a warm, humid world propitious for the development of diverse life forms. Such a hospitable climate helped precipitate the “Cambrian Explosion” of living organisms, a period during which the ancestors of most major animal groups appeared in the fossil record for the first time.[5]The period from about 300 million to 280 million years ago saw the Earth once again in the deep freeze—in the harshest years of the Permo-Carboniferous Ice Age; one whose severity exceeded that of the later Pleistocene glaciation. There was one supercontinent on Earth then, referred to by geologists as Gondwanaland. It was only later that the continents split and drifted apart; and across the Gondwanaland supercontinent the fossil record shows the baneful impact on plant life of the Permo-Carboniferous glaciation; only the hardiest breeds survived.[6]Around 250 million years ago the Earth was again hot but now so dry that huge salt deposits formed from the evaporation of sea water.[7] Fast forward some 150 million years to approximately 100 million years ago, and the Earth was still uniformly hot but humid again, and dinosaurs roamed its surface as the dominant land vertebrates.[8]Moving closer to our day, by 55 million years ago the Earth sweltered under the blazing heat of the Eocene Thermal Maximum, when global temperatures increased by approximately 9–10.8 degrees Fahrenheit (roughly 5–6 degrees Celsius), with perhaps even more pronounced warming in the Arctic region.[9] Widespread extinctions were associated with this “heat wave” lasting approximately 100,000 years, but the ancestors of many of Earth's current life forms survived.[10]Additionally, throughout geologic time we find numerous examples of non-cyclical but, rather, sudden and catastrophic natural climate change. Catastrophic Climate Change The geological record indicates five major mass extinctions during the past 450 million years.The causes are disputed. Renowned geologist, Dr. Tony Hallam, describes several leading theories. One, that of bolide impact—the collision of comet or asteroid with the Earth—is today widely believed to have provided the coup de grace to dinosaurs, life forms already, at that time, dying off after 165 million years as Earth’s dominant land vertebrates.[11] The land impact of a high-speed bolide would inject into the atmosphere an immense dust cloud that could envelop the Earth for perhaps up to a year. As Hallam states regarding this purported cause of the end-Cretacean mass extinction:  “Such a cloud would have blocked out sunlight, thereby stopping photosynthesis and resulting in a collapse of the food chain, with consequent starvation and mass extinction."[12]Evidently, the Earth has suffered through perhaps a dozen of these massive collisions in its history, destroying millions of life forms whose existence we know of only via the fossil record. Climate scientist, Dr. Fred Singer, writes of them:  “The Earth’s collisions with massive missiles from outer space explode billions of tons of ash and debris into the Earth's atmosphere, darken the skies, and virtually eradicate the growing seasons for years at a time.”[13]Another candidate that could potentially wreak major extinction is volcanic activity. A relatively recent example of the baneful global reach of volcanic activism was the Tambora eruption on the Indonesian island of Sumbawa in April 1815. Gillen D’Arcy Wood, in his study of Tambora’s destructive consequences, writes of “the cascading worldwide weather disasters in its three-year wake.”[14]  Part of the problem, Wood says, is “the sun-blocking dust veil ...[which] might linger above the earth for up to three years.”[15]  Perhaps worse is the release of gaseous sulfur compounds that rise into the stratosphere, where they combine with the limited water available to form droplets of sulfuric acid; these droplets reflect a substantial amount of sunlight away from the Earth and back into space—and can cause significant global cooling for up to two years.[16]The lead candidate for causation of the end-Triassic mass extinction—that expunged approximately twelve percent of the planet’s vertebrate families—is a series of massive volcanic eruptions in Brazil, the east coast of North America, Morocco, and Spain.[17]Related, paleobiologist , Dr. Douglas Erwin, the leading authority on the end-Permian catastrophe that wiped out approximately ninety-five percent of Earth's life forms,  credits on-going eruption of Siberian flood basalts as the likeliest cause. The massive quantity of dust spewed into the atmosphere could lower temperatures for years; but worse would be the conversion of sulfate aerosols to sulfuric acid, then to be poured down as acid rain. Combine these and other factors, says Erwin, and the result is horror that only Dante could adequately describe.[18]Hallam also points out other possible causes of mass extinctions, such as severe climate change, especially pronounced cooling periods.[19]One conclusion is abundantly clear: The power of nature—whether via bolide impact, massive volcanism, and/or other causal agents—to wreak sudden cataclysms inflicting both widespread climate change and massive devastation of life borders on the indescribable.But cyclical—not fitfully irregular—climate change is most relevant to understanding the warming of our era.  The Pleistocene Ice AgeAlthough it is today not widely discussed, the Earth is currently basking in the relatively higher temperatures of an interglacial warm period—known as the Holocene—of the on-going Pleistocene Ice Age. In contrast to modern hysteria regarding global warming, a great deal of geologic evidence points towards the return of thick Northern Hemisphere glaciers within the next 1,000 to 10,000 years.[20] Macdougall writes, “It is often not appreciated that today’s climate is just a geologically short warm spell in this continuing ice age.”[21]Roughly 30 million years ago, ice sheets formed and expanded in Antarctica. These were followed by extensive glaciation in Greenland approximately 18 million years ago. Then perhaps just under 3 million years ago glaciers moved into North America. Over the past 2-3 million years, the Northern Hemisphere has seen repeated cases of extensive glaciation—and of thick ice sheets extending well into northern portions of what is today the United States.[22] Indeed, the sites of cities such as Montreal and Chicago were buried beneath ice sheets perhaps thousands of feet thick.[23]Over the past million years, the recurring Northern Hemisphere ice ages have occurred on 100,000 year cycles. These include roughly 80,000 to 90,000 years of colder climate and advancing ice interspersed with roughly 10,000 to 20,000-year interglacial periods of warmer climate and retreating ice.There are also cycles within climate cycles. About 12,500 years ago, the latest wave of Northern Hemisphere glaciation began, lasting for roughly 1000 years—until about 11,500 years ago, when northern regions warmed suddenly from ice age conditions to almost current temperatures.[24] The past 11,500 years, continuing to our day, make up the Holocene interglacial warm period—a relative warm spell in the midst of what is still one of Earth’s colder periods: the Pleistocene Ice Age. The bad news is that, measured in terms of geologic time, if the Earth’s history is an accurate guide, glaciers will soon return to more southerly latitudes of the Northern Hemisphere.[25]  The Past MillenniumAs part of this on-going cycle there have been numerous other periods, leading up to our own day. One, the Medieval Warm Period (roughly 900–1300 AD) saw temperatures in the Northern Hemisphere approximately as warm as they are today,[26] enabling the Norse to colonize both Iceland and Greenland, the English to plant grapes and establish vineyards, the Norwegians to harvest crops at higher elevations than for a millennium and the Scots at elevations higher than today.  Across Europe, higher temperatures contributed to crop yields more robust than in the colder period that ensued.[27] Wine was produced in northern European climes that today are too cold for growing grapes, indicating that northern temperatures might have been 1 to 1.4 degrees Celsius (roughly 1.8 to 2.5 degrees Fahrenheit) warmer than at current times.[28]Following this was the Little Ice Age (roughly 1300-1800). We know that temperatures in Europe, the North Atlantic, and North America were generally cooler than today. Alpine glaciers advanced, encroaching on farms and human habitations. The Norse were forced by harsher climate to abandon their earlier Greenland settlements. Inuit peoples in the Arctic region began migrating south. In parts of Germany, Holland, and Denmark, the fierce storms associated with colder weather destroyed large swathes of agricultural land, leading to widespread famine.[29]During the depths of the cold temperatures, in the 1690s, crops were widely devastated. As a result, tens of thousands (of a total population under 2 million) starved to death during the so-called “Lean Years” in Scotland.[30] Even more disastrous, during the same decade, in Finland, famine wiped out twenty-five to thirty-three percent of the country’s entire population. A leading historian terms it “the most terrible event in European history.”[31]   In the past several thousand years, there have been other eras of naturally-cycling climate change, as well. [32]The above data regarding the Earth's swings between colder and warmer periods is sufficient to establish an important conclusion: Cyclical natural climate change has been a regularly recurring feature of the Earth across both geologic and more recent times.Subsequent to these climate eras, from approximately the late-nineteenth century until our day, the Earth warmed slightly—by roughly 2.16 degrees Fahrenheit (approximately 1.2 degrees Celsius). John Houghton, a professor of atmospheric physics at Oxford University, a co-chair of the IPCC’s scientific assessment working group, and lead editor of the first three IPCC reports, writes that, in the past several decades, minimum temperatures over land have increased approximately twice as much as have maximum temperatures. Further, Houghton reports that, because of the warming, global mean sea levels during the twentieth century increased at an average annual rate of 1–2 millimeters, Arctic sea-ice extent and thickness thinned by forty percent in recent decades during months of late summer to early autumn, non-polar glaciers during the twentieth century retreated substantially, and growing seasons in the Northern Hemisphere lengthened by about one to four days.[33]  Our era, consequently, is known as the Modern Warm Period.It should be perennially remembered that the various proxies described above indicate that Northern Hemisphere temperatures during the Medieval Warm Period--centuries before initiation of human industrialization--were slightly higher than during our day.  The Necessity to Affirm, Not Deny Climate Change Notice further that there are cycles within climate cycles. For example, as Dr. Macdougall points out, for approximately the past 50 million years the Earth has been gradually cooling. But, during the Roman Warm Period, the Medieval Warm Period, and the Modern Warm Period, the Earth warmed. Further, even within the Modern Warm Period there have been cycles; for example, although the Earth generally warmed from the late-19th century to today, there was, in the midst of this warming, a cooling trend from approximately 1940 to 1975,[34] resulting in Newsweek’s now-infamous 1975 article fretting about a possible looming ice age.[35] Amidst all of this is the on-going 2-million-year Pleistocene Ice Age, with its recurring cycle of glaciations followed by milder inter-glacial warm periods.Any rational human being, examining the above facts, must affirm the reality of climate change. Indeed, we must so strenuously affirm its reality that we feel compelled to raise the eminently logical and too-infrequently asked questions:  Is the Earth's climate always changing?Is there ever a time when Earth's climate is not changing? Is climate but one more instance of the incessantly dynamic nature of the physical world? From the instant a living being is born, for example, is there ever a moment when it is not aging? Does the Earth stop momentarily in its rotation—so that there is a break in the day/night cycle—or does it whirl relentlessly on? Does our planet ever cease revolving around the sun, thereby disrupting the pattern of the seasons, or does it forge ceaselessly forward? The erosion of mountains to molehills, as a final example, is a process so agonizingly slow that the resulting disparity in stature reveals the inexorability of wind, rain, and storm, forces never granting the exposed peaks a moment's respite.Two millennia ago, the Greek philosopher, Heraclitus, observing the ubiquity of process in the natural order, theorized that change itself—activity or dynamism—is the fundamental reality, rather than entities that, in various forms, undergo change; a logical error brilliantly corrected by Aristotle. Both thinkers, however, were deeply impressed by the robust dynamism of the empirical world.Is climate any less dynamic than these other processes of nature? There is no logical reason that it should be—and a great deal of empirical data suggests that it is not. Indeed, the IPCC itself, in its 2001 report, acknowledged: “Climate has always varied on all time scales…”[36]Climate, in contrast to ever-changing weather patterns, denotes a long-term condition. So climate is not--by the minute, the day, the year, or even the decade--always changing. But the evidence shows that climate periods are often changing.  This point can be summarized succinctly: Climate periods are often changing; probably generally changing; perhaps always changing.It is precisely this context, an appropriate timescale, that many (if not all) AGW theorists ignore. A stockbroker, who tried to convince investors to buy a stock based on its performance in the last sixty seconds, while blanking out decades of data, would be ignoring vastly less relevant information than do the majority of today’s supporters of man-made global warming.The accusation of "climate change denier" is, consequently, egregiously inaccurate when hurled at persons who examine this context and recognize the reality of natural, cyclical, and likely incessant change of climate periods.The accusation is accurate, however, when leveled against some leading supporters of the AGW hypothesis. Dr. Michael Mann, for example,  a respected climate scientist and lead author for the IPCC, developed the infamous "hockey stick" graph, purporting to show that, for roughly 1,000 years prior to the 20th century, Northern Hemisphere temperatures had been relatively stable, perhaps even declining slightly, then sharply rising after 1900 (hence the hockey stick shape of the graph). In effect, Mann's methodology "air-brushed" out of existence the Medieval Warm Period; if accurate, Mann's findings would show a strong and unique correlation between human emissions of carbon dioxide and rising temperatures. However, Mann's methodology was seriously flawed and exposed as such by Dr. Edward Wegman, a leading statistician. The hockey stick graph, a featured aspect of the IPCC's 2001 report, was subsequently dropped by the IPCC. The Medieval Warm Period had to be acknowledged as real.[37]But Mann, some of his IPCC colleagues, and the environmentalist movement more broadly continue to support the hockey stick hypothesis.According to Mann and his supporters, Northern Hemisphere temperatures were relatively flat for roughly 1,000 years, and the natural climate cycles from the Dark Age Cold Period to the Medieval Warm Period to the Little Ice Age were non-existent (or, at most, greatly over-exaggerated).Who, then, is actually guilty of denying climate change?[38]Nevertheless, even when recurring natural climate cycles are recognized, an important question can and must be raised: What is the relationship between ongoing climate change and human activity?  The AGW Hypothesis—And Its FlawsThere is, in truth, a greenhouse effect, for which we all should be grateful; for without it, the Earth would be too cold to support life. Carbon dioxide is indeed a greenhouse gas, serving to trap heat near the Earth’s surface, contributing to rising temperatures. The late paleontologist, Dr. Robert Carter, stated the facts simply: It is, he says, an established physical property of carbon dioxide that it “absorbs space-bound infrared radiation, thereby increasing the energy available at the Earth’s surface for warming or increased evaporation.”[39]Since the Industrial Revolution, human beings have pumped increasing amounts of carbon dioxide into the atmosphere. At the beginning of the Industrial Revolution, for example, scientists believe that the atmospheric concentration of CO2 was around 280 parts per million (ppm). By 1958, it stood at approximately 315 ppm. Today, it stands at just over 400 ppm.[40] Since the mid-nineteenth century, Earth’s temperature has also risen. Therefore, there is both an established physical mechanism by means of which CO2 contributes to increased warming—and a very rough correlation over the past 150 years between rising atmospheric accumulation of CO2 and rising temperatures.Does all this support the conclusion that man-made CO2 is the predominant, perhaps exclusive cause of modern warming?  There is, among several others, one very inconvenient truth for AGW theorists. For at least the past 240,000 years, Earth’s warming has preceded rising CO2 levels, not vice versa. Analyses of ice cores from Antarctica’s Vostok Glacier, for example, reveal that over the Earth’s past three glaciations and ensuing warmer periods, rising CO2 levels lag behind rising temperatures by several centuries.  Oregon State Climatologist, George Taylor, stated, “In other words, CO2 changes are caused by temperature changes.”[41]Israeli astrophysicist, Dr. Nir Shaviv, commented: “In all cases where there is a good enough resolution, one finds that the CO2 lags behind the temperature by typically several hundred to a thousand years. Thus, the basic climate driver that controls the temperature cannot be that of CO2.”[42] Dr. Robert Carter concurred: “The ice core data show conclusively that, during natural climate cycling, changes in temperature precede changes in carbon dioxide by an average 800 years or so.”[43] Climate scientist, Dr. Fred Singer agrees: “Global warming has produced more CO2 rather than more CO2 producing global warming.”[44]Notice further that, during the Modern Warm Period, the correlation between atmospheric build-up of CO2 and rising temperatures is inexact.  Dr. Singer points out: “Most of the current warming occurred before 1940,” prior to a large accumulation of man-made CO2 in the atmosphere.[45] Then, between 1940 and 1975, in the post-World War II period, booming industrialization injected large amounts of CO2 into the atmosphere while the Earth cooled.[46] Finally, early in the twenty-first century, CO2 concentrations have shot up to 400 ppm but, when naturally-occurring El Nino effects are subtracted from the data set, there has been no measurable warming since 1998. Dr. Richard Lindzen, professor of atmospheric physics at MIT, a former lead author for the IPCC, and one of the world's most eminent climate scientists, is but one of many scientists who point out this pause in warming.[47]The full truth is that increasing accumulations of atmospheric CO2 is a cause of warming, but is merely one factor of many inducing climate changes—and is often overwhelmed by other, more powerful causes.[48] One example of this occurred about 440 million years ago, during the Ordovician Ice Age, when atmospheric accumulations of CO2 were 10-17 times higher than today’s and yet the Earth was in the depths of a severe glaciation.[49]Part of the reason that CO2 is a weak cause of warming is that it is a trace gas in Earth’s atmosphere. Today, CO2 stands at 400 parts per million, meaning that 999,600 parts per million of the atmosphere are composed of other gases—78 percent nitrogen, 21 percent oxygen, and 1 percent trace gases, one of which is CO2. CO2 constitutes but four one-hundredths of one percent of Earth’s atmosphere. Expressed as a percent, CO2 constitutes merely 0.04 percent of the atmosphere; meaning that 99.96 percent of Earth’s atmosphere is constituted by gases other than CO2. Such a minute component of our atmosphere possesses neither the presence nor the power to cause substantial, much less catastrophic warming.So, if over the past several hundred thousand years increasing CO2 levels have not driven rising temperatures, then what has?A clue is that, in recent years, Mars has also warmed.[50] Eminent Russian astrophysicist, Dr. Habibullo Abdussamatov, head of the Space Research Laboratory at St. Petersburg’s Pulkovo Astronomical Observatory, says simply, “Mars has global warming, but without a greenhouse and without the participation of Martians.”[51]Is there a positive relationship between the warming of two different planets in our solar system? Do these two warmings share a common cause?  The Sun-Climate ConnectionDr. Abdussamatov believes the warming of both planets is caused in part by cycles in the Sun’s overall power. Long-term increases in total solar irradiance (TSI) are a primary cause in a complex system that leads to global warming, here and elsewhere. He says: “The predominating factor influencing climate changes (geophysical effects lasting for decades) is alterations in a general two-century-long cycle of solar activity defined primarily by corresponding changes in TSI.”[52]Between 1978 and 2003, the Sun’s radiation increased by nearly 0.05 percent per decade.[53] The Sun’s output is so immense that even such a small increase is equal to the full amount of human energy use.[54] Unsurprisingly, this was a period of general global warming.However, such small differences in TSI are, in themselves, insufficient to account for either Earth’s most recent warming or for its repeated warming and cooling cycles. The Sun’s cycles may trigger the recurring changes in climate but some terrestrial process(es) must amplify the effect. Which process(es)?Before answering this question, it is necessary to make a cognate point: Regarding one important relationship, there is little mystery. Scientists have long known that the oceans store vast quantities of CO2; indeed, the oceans contain roughly 50 times as much CO2 as does the atmosphere.[55] When the Earth warms, the oceans release greater amounts of CO2 into the atmosphere. States Dr. Abdussamatov: “If the temperature of the ocean rises even a little, gigantic amounts of CO2 are released into the atmosphere through the evaporation of water…. It is no secret that increased solar irradiance warms Earth’s oceans, which then triggers the emission of large amounts of carbon dioxide into the atmosphere.”[56]But what are the terrestrial processes that amplify the effects of increased TSI, leading to global warming? One, discovered by leading Danish astrophysicists, Dr. Eigil Friis-Christensen and Dr. Henrik Svensmark, involves cosmic rays and the previously-little-understood process by which clouds are formed.[57] Meteorologists have long known that low-lying cloud cover helps keep the Earth cool, but they did not understand the causes of clouds. In 2006, Svensmark and his team permitted naturally occurring cosmic rays to filter in through their laboratory ceiling and interact with the chemistry of the lower atmosphere they’d replicated in the lab. “What they found left them agape: A vast number of floating microscopic droplets soon filled the reaction chamber. These were ultra-small clusters of sulfuric acid and water molecules—the building blocks for cloud condensation nuclei—that had been catalyzed by the electrons released by the cosmic rays.”[58]They established that cosmic rays (energy released by exploding stars, i.e., super-novae) enter Earth’s atmosphere and release electrons in the air. These electrons encourage “the clumping of molecules to make micro-specks, capable of gathering into the larger specks needed for cloud formation.”[59] Svensmark’s team had identified a physical mechanism by means of which cosmic rays effectuate Earth’s cloud cover.Dr. Eugene Parker, one of the world’s most accomplished astrophysicists, discoverer of the solar wind, wrote about Svensmark’s breakthrough: “It is our good fortune that, some years ago, Henrik Svensmark recognized the importance of cloud cover in the temperature control of planet Earth. Clouds are highly reflective to incoming sunlight. Svensmark also recognized that the individual water droplets that make up a cloud form mostly where ions have been created by passing cosmic ray particles, thereby tying cloud formation to the varying cosmic ray intensity. That is to say, cosmic rays control the powerful ‘cloud valve’ that regulates the heating of the earth.”[60]When the Sun emits greater amounts of radiation, its magnetic field is strongest. This bolstered magnetic field protects Earth from cosmic ray bombardment. Fewer cosmic rays mean less clumping of molecules, which means formation of fewer low-lying clouds. The Sun’s increasing TSI directly accounts for only a small percentage of Earth’s rising temperatures. But the inhibiting of cooling cloud cover accounts for a good deal more.[61]Celestial events and relationships can also explain the Earth’s cooling. The Earth’s elliptical orbit around the Sun is eccentric; the shape of the orbit at times is more elliptic, at times less. Therefore, the Earth’s farthest remove from the Sun is not uniform. Sometimes its greatest orbital extent from the Sun is more distant than at other times. Additionally, the Earth’s tilt on its axis varies between roughly one degree less than its current 23.5 and one degree more.  Finally, the Earth wobbles on its axis so that the direction of the Earth’s tilt varies over time; at times the Northern Hemisphere will, in effect, “lean” toward the Sun and at other times away  from it.[62]All of these factors are cyclical, known today as “Milankovitch Cycles,” after Serbian mathematician, Milutin Milankovitch, who put the theory on its modern footing.[63]  When: 1. The Earth is at its farthest remove from the Sun at the same time that 2. The Northern Hemisphere “leans” away from, rather than toward, the Sun and 3. The Earth’s angle of tilt on its axis causes the Northern Hemisphere “lean” to be at its maximal point, at these times the Northern Hemisphere will receive its least amount of solar radiation and suffer through its coldest winters and coolest summers.[64]These three astronomical factors align roughly every 100,000 years—which corresponds almost exactly to the Northern Hemisphere glaciations of the past two million years. Geologists consider such correspondence unlikely in the extreme to be coincidence.But again, the change in solar radiation reaching the Earth is too slight in itself to cause significant change in terrestrial temperatures; amplifying factors are necessary to cause the plunge into an ice age. Scientists believe there are several. One is that decreased solar irradiance means colder winters and the likelihood of increased snowfall, including at more southerly latitudes—and cooler summers during which will occur diminished melt. Increased surface snow and ice reflect away more sunlight from the Earth’s surface, contributing to a downward temperature spiral. Scientists believe there are other contributing factors, as well. One is that greater disparity of temperatures between the polar region and the equator will increase winds, which would affect ocean currents, resulting in diminished heat carried northward by the Gulf Stream. It is also possible that increased wind intensity will carry more moisture northward from the tropics, causing increased precipitation, which, in those temperatures, will mean more snow fall.[65]The specific terrestrial processes by means of which diminished solar radiance gets translated into conditions sufficiently cold for an ice age are not yet fully understood. But two important points are clear: 1. The underlying cause of the Pleistocene’s recurring waves of glaciation is the complex relationship between the Earth and the Sun 2. Diminished solar irradiance triggers a series of terrestrial processes that, taken in concert, substantially drive down temperatures.No doubt there are further complexities regarding the Sun’s various recurring cycles and the processes by which greater and lesser amounts of solar radiation similarly get amplified into earthly climatic effect. But, as Dr. Singer argues, there is a striking long-term correlation between the Sun’s emission of radiation and Earth’s climate that simply cannot be overlooked.[66] Dr. Singer displays a graph charted by astrophysicists, Dr. Sallie Baliunas and Dr. Willie Soon, showing the correlation between solar irradiance and Earth’s Northern Hemisphere temperatures during the period between 1750 and 2000, a full 250 years. The temperatures, through wide and dramatic variations, track closely to the Sun’s emission of radiation. As Dr. Singer notes, “Given the variability of the temperatures, the close relationship between the two is startling.”[67]Unfortunately, if the Sun-based climate theory is accurate, the Earth is heading toward a cooling period. Dr. Abdussamatov maintains that, “Solar irradiance has begun to fall, ushering in a protracted cooling period beginning in 2012-2015. The depth of the decline in solar irradiance reaching Earth will occur around 2041. . . . and will inevitably lead to a deep freeze around 2055-60.”[68]Indeed, given the absence of (non-El Nino-induced) measurable warming over the past 15-18 years, the Earth’s cycle from warmer to cooler periods may have already begun.  Important Final PointsMan’s earliest ancestors evolved approximately 6 million years ago; the Homo group, including sapiens, arose perhaps 2 million years ago; and our species was distinguished roughly 200,000 years ago.[69] Therefore, cyclical climate change pre-dates man by, at minimum, hundreds of millions of years.  Forces of nature are vastly more powerful than the forces of man. Can we retard a hurricane, for example, bearing down on our shores?  Smother massive volcanism from spewing millions of tons of ash, grit, and dust into the atmosphere, blackening the skies and blocking the sun? Impede an advance of northern glaciers poised to scrape human habitations from their current locales and deposit them, as twisted wreckage, hundreds of miles to the south?  We cannot.Forces of nature have long—perhaps always—caused cyclical climate change. These changes—such as ice ages and their cessation—involve temperature swings vastly more dramatic than the mild warming of our era.Astronomical factors are responsible for the cycles of the Pleistocene Ice Age. Are we to suppose that human emission of carbon dioxide is sufficiently powerful to bring down upon the Earth an equivalent ice age—or its melt? The Sun can do this. Man cannot.Additionally, the best proxy data we have indicates that over geologic time Earth's temperature  range has varied from roughly 50 degrees to 72 or 73 degrees Fahrenheit (10 degrees to 22 or 23 degrees Celsius). The best estimate we have today is that the Earth's temperature is currently in the range of 59-60 degrees Fahrenheit (roughly 15 degrees Celsius).[70] The Earth's temperature is, by several degrees, currently nearer the cooler rather than the warmer end of its historic spectrum.The Earth's range over geologic time is one more data point showing nature's power to cause temperature swings substantially greater than that of the Modern Warm Period.Finally, we have seen some of the primary causal agents inducing Earthly change of climate: 1. the Sun's spatial alignment relative to the Earth 2. the Sun's cycling in its emission of radiation 3. cosmic ray bombardment of Earth's atmosphere, actuating cooling cloud cover 4. the natural oscillations of Earth's ocean currents, such as El Nino, La Nina, and others.[71]The Earth is an immense meet-up of inter-locking, diverse, and dynamic causal factors promoting climate change; related, the planet itself is, relatively, but one dust point in a vastly more immense solar system and galaxy, which unleash yet more diverse natural forces contributing to terrestrial climate change.Carbon dioxide, whether from natural or man-made sources, is merely one agent in this vast network of causal forces--and, existing in but minute doses in our atmosphere, necessarily a secondary one.  ConclusionsOne: Natural-caused, cyclical, and perhaps incessant climate change has occurred for hundreds of millions of years, perhaps longer. The temperature swings caused thereby were, at times, vastly more extensive than the mild warming of our era. For at minimum the past several hundred thousand years atmospheric CO2 buildup lags behind temperature increase. The logical conclusion? Natural forces, not man-made ones, are the overwhelming factor driving modern climate change.Two: The small warming that we do have is something to be welcomed and celebrated—not something to be feared or curtailed. It is the colder, not the warmer periods of our planet’s history that have been baneful to life. Extensive glaciation killed plant life and drove animals to warmer climes. It was during the warmer interglacial periods that life rebounded. The “Cambrian Explosion” of emerging life forms occurred during a warm, humid period of Earth’s history, not during one of its colder ones.  Human beings flourished throughout the Medieval Warm Period and suffered during the ensuing Little Ice Age.  The Modern Warm Period, like its medieval predecessor, is therefore a boon to be savored prior to the Earth's next extended cold snap. Dr. Singer states:  “History, science, and our own instincts tell us that cold is more frightening than warmth. . . . The climate event that deserves real concern is the next Big Ice Age. . . . though it may still be thousands of years away.”[72]Three: By what means can human beings adapt to pernicious, even lethal climate changes?  To protect human life from ice ages, massive volcanism, bolide impact, or whatever other scourges nature has in its arsenal, we must immensely increase our knowledge. How do we do that?Here, history, economics, and rational philosophy combine to teach us an invaluable lesson.  Human beings must uphold two principles: 1. We must support a culture of reason, a commitment to observation-based rationality as our means of gaining knowledge—and not subordinate reason to feelings or faith 2. We must adopt a politics of individual rights and of capitalism, and put a definitive halt to Western Civilization's regress into socialism.When we do this, we can make advances in every field of cognition, as in late-19th and turn-of-the-20th centuries America, when such geniuses as Thomas Edison, Alexander Graham Bell, the Wright brothers, George Washington Carver, William James, Mark Twain (and many others) were free to advance the fields of electrical engineering, telecommunications, aeronautical engineering, agricultural science, experimental psychology, and literature respectively.When human beings uphold a reverence for reason and a respect for each individual's inalienable right to his own life and his own mind—and only then—can we develop the science and technology to adapt to such climate calamities as ice ages or the extended "heat wave" of the Eocene Thermal Maximum. By developing central air providing heat and air conditioning, insulated homes, thermal clothing, sun screen, advances in medicine, nuclear fusion reactors, geothermal energy, modern methods of transportation and hence of evacuation, and other forms of progress as unimaginable to us as were airplanes, computers, and the Internet to our ancestors just two centuries ago, we will learn to adapt to severe climate change, whether caused by human forces or, far more likely, the awesome power of nature.But to do this, we need reason, individual rights, and capitalism. Nothing less—and nothing else—will enable us to flourish—or even to survive.Four: The AGW hypothesis is mistaken regarding both points two and three delineated at the outset: Modern warming is neither man-made nor pernicious. Rather, it is natural and beneficial.    Additionally, supporters of the AGW hypothesis generally propose, as a panacea, massive government controls of industry and a steep plunge into statism—policies that would strangle the innovativeness and entrepreneurship necessary to combat the climate dangers regarding which they purportedly warn.Supporters of the AGW hypothesis drop the extended historic context within which modern warming must be understood, they fail to recognize that warm periods in contrast to cold ones are beneficial to life, they ignore the inconvenient truth that atmospheric CO2 buildups follow rather than precede global warming, they are heedless of leading astrophysicists who study the sun-climate connection, and they are profoundly mistaken regarding their proposed solution to “dangerous” climate change.For all of these reasons, the AGW hypothesis must be rejected.    [1]  Doug Macdougall, Frozen Earth: The Once and Future Story of Ice Ages (Berkeley, California: University of California Press, 2006), 8[2] Macdougall, Frozen Earth, 8.[3] Macdougall, Frozen Earth, 8.[4] Macdougall, Frozen Earth, 150–160, 209–211.

Matt Ridley on How Fossil Fuels are Greening the Planet

Apr 21, 2017 | Sci-Tech

https://youtu.be/S-nsU_DaIZE“[H]alf of that greening comes from carbon dioxide itself. In other words, the fact that we're putting more carbon dioxide into the air means there's more fuel to grow plants and when a plant has more carbon dioxide in yet doesn't have to open its pores so much so it doesn't lose so much water in absorbing the carbon dioxide that it needs to grow and so there's tons of experiments now showing that plants grow faster if there's more carbon dioxide in the air; roughly speaking on average for a 200 parts per million increase in carbon dioxide in the air you get a 30% improvement in plant growth. That's experiments both in the field and in the laboratory. So it's really quite a remarkable phenomenon here because of the burning of fossil fuels we're making the planet greener. It's an astonishing discovery I think. I think it's rather amazing and of course it's an incredibly unwelcome discovery for the environmental movement. They don't want to hear this at all and how is it possible…” – Matt Ridley

NASA Telescope Reveals Seven Earth-Size, Habitable-Zone Planets Around Single Star

Feb 24, 2017 | Sci-Tech

NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water – key to life as we know it – under the right atmospheric conditions, but the chances are highest with the three in the habitable zone. This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” said Thomas Zurbuchen, associate administrator of the agency’s Science Mission Directorate in Washington. “Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.”At about 40 light-years (235 trillion miles) from Earth, the system of planets is relatively close to us, in the constellation Aquarius. Because they are located outside of our solar system, these planets are scientifically known as exoplanets.This exoplanet system is called TRAPPIST-1, named for The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile. In May 2016, researchers using TRAPPIST announced they had discovered three planets in the system. Assisted by several ground-based telescopes, including the European Southern Observatory's Very Large Telescope, Spitzer confirmed the existence of two of these planets and discovered five additional ones, increasing the number of known planets in the system to seven.The new results were published Wednesday in the journal Nature, and announced at a news briefing at NASA Headquarters in Washington.This artist's concept shows what each of the TRAPPIST-1 planets may look like, based on available data about their sizes, masses and orbital distances.

Using Spitzer data, the team precisely measured the sizes of the seven planets and developed first estimates of the masses of six of them, allowing their density to be estimated. Based on their densities, all of the TRAPPIST-1 planets are likely to be rocky. Further observations will not only help determine whether they are rich in water, but also possibly reveal whether any could have liquid water on their surfaces. The mass of the seventh and farthest exoplanet has not yet been estimated – scientists believe it could be an icy, "snowball-like" world, but further observations are needed."The seven wonders of TRAPPIST-1 are the first Earth-size planets that have been found orbiting this kind of star," said Michael Gillon, lead author of the paper and the principal investigator of the TRAPPIST exoplanet survey at the University of Liege, Belgium. "It is also the best target yet for studying the atmospheres of potentially habitable, Earth-size worlds."In contrast to our sun, the TRAPPIST-1 star – classified as an ultra-cool dwarf – is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system. All seven of the TRAPPIST-1 planetary orbits are closer to their host star than Mercury is to our sun. The planets also are very close to each other. If a person was standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth's sky.The planets may also be tidally locked to their star, which means the same side of the planet is always facing the star, therefore each side is either perpetual day or night. This could mean they have weather patterns totally unlike those on Earth, such as strong winds blowing from the day side to the night side, and extreme temperature changes.Spitzer, an infrared telescope that trails Earth as it orbits the sun, was well-suited for studying TRAPPIST-1 because the star glows brightest in infrared light, whose wavelengths are longer than the eye can see. In the fall of 2016, Spitzer observed TRAPPIST-1 nearly continuously for 500 hours. Spitzer is uniquely positioned in its orbit to observe enough crossing – transits – of the planets in front of the host star to reveal the complex architecture of the system. Engineers optimized Spitzer’s ability to observe transiting planets during Spitzer’s “warm mission,” which began after the spacecraft’s coolant ran out as planned after the first five years of operations."This is the most exciting result I have seen in the 14 years of Spitzer operations," said Sean Carey, manager of NASA's Spitzer Science Center at Caltech/IPAC in Pasadena, California. "Spitzer will follow up in the fall to further refine our understanding of these planets so that the James Webb Space Telescope can follow up. More observations of the system are sure to reveal more secrets.”Following up on the Spitzer discovery, NASA's Hubble Space Telescope has initiated the screening of four of the planets, including the three inside the habitable zone. These observations aim at assessing the presence of puffy, hydrogen-dominated atmospheres, typical for gaseous worlds like Neptune, around these planets.In May 2016, the Hubble team observed the two innermost planets, and found no evidence for such puffy atmospheres. This strengthened the case that the planets closest to the star are rocky in nature."The TRAPPIST-1 system provides one of the best opportunities in the next decade to study the atmospheres around Earth-size planets," said Nikole Lewis, co-leader of the Hubble study and astronomer at the Space Telescope Science Institute in Baltimore, Maryland. NASA's planet-hunting Kepler space telescope also is studying the TRAPPIST-1 system, making measurements of the star's minuscule changes in brightness due to transiting planets. Operating as the K2 mission, the spacecraft's observations will allow astronomers to refine the properties of the known planets, as well as search for additional planets in the system. The K2 observations conclude in early March and will be made availableSpitzer, Hubble, and Kepler will help astronomers plan for follow-up studies using NASA's upcoming James Webb Space Telescope, launching in 2018. With much greater sensitivity, Webb will be able to detect the chemical fingerprints of water, methane, oxygen, ozone, and other components of a planet's atmosphere. Webb also will analyze planets' temperatures and surface pressures – key factors in assessing their habitability.NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, manages the Spitzer Space Telescope mission for NASA's Science Mission Directorate. Science operations are conducted at the Spitzer Science Center, at Caltech, in Pasadena, California. Spacecraft operations are based at Lockheed Martin Space Systems Company, Littleton, Colorado.
