CO2 Report Debunks Climate Change Catastrophes

For decades, climate change alarmists have generated a host of doomsday scenarios, all based on the theory of anthropogenic global warming: human CO2 emissions will force Earth's climate to warm uncontrollably causing all manner of unpleasantness. A new study, published by the Center for the Study of Carbon Dioxide and Global Change, addresses the major predicted effects of global warming head on. Making extensive use of peer reviewed research papers, the dire predictions of climate alarmists are demolished point by point. In fact, the authors conclude that rising atmospheric CO2 concentrations associated with the development of the Industrial Revolution have actually been good for the planet.

The Ocean Plays A Deeper Game

Around 19,000 years ago, oceanic conditions underwent dramatic changes that coincided with a shift in global climate, marking the onset of the Holocene warming. In the North Atlantic, major changes in the Meridional Overturning Circulation (MOC), which carries warm and highly saline surface water north to cooler regions, played a substantial role in regulating climate and levels of atmospheric carbon dioxide. Scientists are now convinced that the ocean absorbed, stored, and released vast quantities of carbon in the past, playing a major role in the end of the last Pleistocene Ice Age glacial period. Understanding the ocean's role in the past is important to understanding how it may influence climate in the future. A new report in Science shows that the MOC experienced a series of abrupt changes that lasted from decades to centuries, and may have stored and released more CO2 than previously thought.

Erroneous Lessons from Earth's Past

Climate alarmists have been slow to learn that their over-reliance on computer models and unproven theories has harmed their public credibility. In an attempt to counter the richly deserved bad press that climate science has been garnering these days, a number of global warming true believers are trying a different, more fact based approach to scaring the public. One such attempt recently appeared in the journal Science—not as a paper describing original research but as a perspective article. In it, a Senior Scientist at the National Center for Atmospheric Research, in Boulder, Colorado, attempts to “weave together” some carefully selected “threads in the discussion of climate” to arrive at a very familiar and unconvincing conclusion.

Carbon From The Deeps

Scientists believe that carbon released from the ocean floor played a key role in past episodes of climate change. Around 55 million years ago, the break-up of the northeast Atlantic continents was associated with the injection of large amounts of molten magma into seafloor sediments. Formation of the North Atlantic basalts heated the carbon-rich sediments, triggering the release of large quantities of methane and carbon dioxide into the ocean and atmosphere. It has been suggested that this release of previously sequestered carbon was responsible for a 100,000 year period of rapid temperature rise known as the Paleocene-Eocene Thermal Maximum or PETM. Three letters published in Nature Geoscience suggest that carbon trapped beneath the seabed continues to influence carbon dynamics, at least in the deep ocean.

Can't Fix Global Warming!

After coming to the realization that the doom & gloom approach to fighting global warming has become counterproductive, many global warming promoters are now taking a more upbeat “we can fix it” approach. This has riled some of the old guard climate alarmists and led to a backlash. An indication of this can be found in a recent Nature Geoscience editorial that represents a new kind of skepticism—not skepticism of global warming but skepticism that it can be stopped or even blunted. Dismissing the notion that a range of available methods—such as efficiency gains, replacing fossil fuels by nuclear power or renewable energy, land-use changes, etc—can make fighting climate change more tractable, the editorial basically says that the world is going to hell and there is no way around it. If that is true, perhaps we should simply ignore the climate cranks and go on a petrochemical burning binge until the stuff runs out.

The Case For Doing Nothing About Global Warming

Time after time, the public has been harangued by climate change “experts” predicting all form of devastation due to anthropogenic global warming. The Greenland and Antarctic glaciers will melt, as will the sea ice covering the Arctic Ocean. Temperatures will rise by 2-6°C, perhaps more in higher latitudes. Weather patterns will shift, there will be droughts and torrential monsoon rains, cyclones will increase in intensity—where will it all end? Here's a thought, we might find the world a nicer place after a bit of global warming. In fact, given the general cooling trend seen over the Holocene (the period since the last glacial period ended around 14,000 years ago) and the Cenozoic (the time since the dinosaurs died, around 65 million years ago) human CO2 may be, in some small way, the only thing delaying another devastating ice age.

Trends, Rhythms & Aberrations: The Mechanisms of Climate Change

Much has be written and even more said about stopping climate change. The total foolishness of such a quest is obvious to anyone with even the most cursory understanding of Earth's climate over the Past 65 million years. The more science learns about the ever changing nature of climate the more capricious nature appears and the less significant the labors of H. sapiens are revealed to be. To place the ludicrous arguments and unsubstantiated fears of climate catastrophists in perspective, it is instructive to survey Earth's climate since the demise of the dinosaurs—the geological time period called the Cenozoic Era. During this long span of time, Earth's climate has undergone a significant and complex evolution. If one truth has been discovered by human science it is that Earth's climate is always changing, driven, as one set of researchers put it, by trends, rhythms and aberrations—the mechanisms of climate change.

A Dying Breeze

The Alpha Ventus Wind Park is the first of its kind: a deep water wind farm in the stormy North Sea. It is composed of 12 turbines that together will generate 60MW of electrical power. When fully operational, the farm will be able to power 50,000 households. But barely two months after the ceremony opening Germany’s first deep water wind farm, six of the newly installed wind turbines were idle. This was not due to a lack of wind but because of gearbox damage: two turbines had to be replaced entirely, the other four repaired on site. Problems with Alpha Ventus highlight a series of poor decisions—a precipitous move to shut down working nuclear plants, rampant installation of solar cells, and a headlong rush into offshore wind generation among them—that could well have Germany facing blackouts in the not too distant future.

Cancun Crap Out

As you may know, the parasitic bureaucrats and scheming NGO representatives that comprise the dying but still twitching climate change cabal are holding a fun filled, two week blow out in Cancun, Mexico. They have gathered to preach the gospel of global warming and attack those who would thwart their plans for remaking the world according to their own slanted social views. They are keeping a low profile, after the disastrous meeting they had in Copenhagen this past December. For many, the Cancun meeting is basically a time for AGW true believers to lick their wounds and lounge about in the sun with like minded fanatics. For others it is yet another roll of the dice, a gamble that something meaningful will come from the conference. Here are some of the highlights from the bungle on the beach.

CO2 & Temperature During The Middle Eocene Climatic Optimum

Though Earth and its climate are billions of years old, climate science is still very young. So young that surprising new discoveries are constantly being made. One such discovery in the field of paleoclimatology—the study of Earth's climate in the distant past—was the uncovering of a period of great warming around 40 million years ago, in the middle of the Eocene Epoch. In the midst of a general cooling trend beginning at the end of the preceding Paleocene Epoch (~55 mya) there were a number of dramatic, sudden bursts of global warming. The most celebrate of these is the Paleocene-Eocene Thermal Maximum or PETM, when surface temperatures rose by 5-7°C. Recently, science has discovered another hot interval 15 million years later during the Middle Eocene. Named the Middle Eocene Climatic Optimum (MECO), it marked a time when deep sea temperatures rose about 4-5°C and atmospheric CO2 levels peaked. As new information is uncovered, climate scientists are scrambling to interpret what caused this second, more sustained period of warming and what it may mean for current climate conditions.

Fighting CO2 Endangers Raptors

If advocates for green, renewable energy are to be believed, wind farms do not threaten endangered bird species like eagles, hawks and owls. A recent article in Science implies that problems at the Altamont Pass Wind Resource Area (APWRA) in California have been reduced by spacing turbines farther apart and removing turbines from problematic sites. But on-site scientific studies have revealed that the kill rate for all birds, and for birds of prey in particular, have not been reduced and may have even increased. It seems that some eco-activists are so committed to expanding wind power as a way to fight global warming that they are turning a blind eye to the slaughter in the skies. How can these duplicitous greens be trusted if they are willing to drive endangered species to extinction in the name of reduced CO2 emissions?

Global CO2 Emissions Drop

World wide emission of CO2 from fossil fuel burning decreased by 1.3% in 2009 owing to the global financial and economic crisis says a report in Nature Geoscience. Estimated CO2 emissions from deforestation and other land-use changes (LUCs) have also declined compared with the 1990s. The decrease in greenhouse gas emissions was blamed on the contraction of GDP owing to the global financial crisis that began in 2008. Not so fast, say warmist scientists. They claim that CO2 will rise by 4.8% in 2010, proving that what should be treated as good news is not welcome in climate change circles.

Rapid Paleocene Global Warming Caused Diversity Explosion

One of the scary predictions made about the impact of global warming is the extinction of many current species leading to a crisis in biological diversity. Like most of the speculative effects of global warming, this prediction is not only without scientific basis, it is precisely backward. A new paper in the journal Science, studying the impact of rapid global warming at the Paleocene-Eocene boundary, show that rapid tropical forest diversification occurred without plant extinction. Moreover, diversity seemed to increase at higher temperatures, contradicting previous assumptions that tropical flora will succumb if temperatures become excessive. The tropical rainforest was able to flourish under elevated temperatures and high levels of atmospheric carbon dioxide, in contrast to speculation that tropical ecosystems were severely harmed by the heat.

Ancient Evidence That CO2 Does Not Control Climate

Climate scientists continue to be fascinated with the Paleocene–Eocene Thermal Maximum (PETM), which took place about 55 Myr ago. This period of sudden global warming and increasing atmospheric CO2 represents a possible model our present era of warming climate and growing CO2 emissions. Studying the PETM, therefore, may provide insight into climate system sensitivity and feedbacks. Just such a study, reported in Nature Geoscience, found that CO2 forcing alone was insufficient to explain the PETM warming. Scientists speculate that other processes and/or feedbacks, hitherto unknown, must have caused a substantial portion of the warming during the Paleocene–Eocene Thermal Maximum. Simply put, CO2 did not cause the PETM climate change.

More Lies About CO2

A new paper, penned by a group of known warmist scare mongers, claims to have proof that CO2 is the control knob that regulates Earth’s temperature. Andrew A. Lacis, Gavin A. Schmidt, David Rind, and Reto A. Ruedy, all from NASA's Goddard Institute for Space Studies, are boasting they have experimental proof that “carbon dioxide is the single most important climate-relevant greenhouse gas in Earth’s atmosphere.” Even though this climate alarmist cabal admits that H2O, in the form of water vapor and clouds, accounts for 75% of greenhouse warming, they still claim that that CO2 is king. Why? Because water's contributions are supposedly caused by feedbacks involving carbon dioxide. How have they proven that? By fiddling around with the same biased computer climate models that their other fictitious claims are based on.
