Damn You, Global Warming!

Despite warnings to the contrary, and waning public support, the all purpose boogieman climate change is once again getting credit for the recent spate of natural disasters in the US. Whether its flooding on the Mississippi, rain soaked fields too wet to plant, or rampaging tornadoes laying waste to whole towns the villain behind our misfortune is anthropogenic global warming. Reports from the scenes of devastation are sure to include at least one reference to climate change, which is of course caused by people. In essence, the yammering news media—who always needs a culprit to blame when disaster befalls a group of innocents—has placed the blame squarely back on humanity. That's right, we are responsible for the tragic deaths of hundreds of people caused by storm, flood and tornadoes. The chattering class once again demonstrates that they have bought the IPCC climate change scam: hook, line and sinker. They would rather mindlessly repeat the discredited memes of climate alarmists than think critically themselves.

Killing Kyoto

The ineffective and mostly ignored Kyoto agreement is due to expire in 2012. Climate change activists around the world are girding their loins in preparation for the battle over Kyoto 2, the follow on treaty. Their goal? New regulations for black carbon, methane and driving anthropogenic CO2 emissions to zero. Leaving no bad idea unused, there is talk of implementing a global cap & trade system where developed nations that are able to reduce emissions beyond their Kyoto targets can sell excess reduction credit to other developed nations through the Emissions Trading mechanism. Beyond that, rather than negotiating CO2 emission reduction targets on a nation-by-nation basis—as in the current Kyoto framework—a future level of maximum allowable global temperature increase can be chosen. It is clear that the warmists have made the transition from irrational to delusional.

Direct Removal Of CO2 Impractical

According to a new report from the American Physical Society, Direct Air Capture (DAC) of CO2 using chemicals is not a viable solution for removing greenhouse gases from Earth's atmosphere. DAC involves a system in which ambient air flows over a chemical sorbent that selectively removes the CO2. It is one of a small number of strategies that advocates say could allow the reduction of atmospheric CO2. Prepared for the APS Panel on Public Affairs (POPA), a collection of scientific experts, the report claims to be a technology assessment containing no policy or funding recommendations. Unfortunately for its advocates, the APS report finds the approach untenable for technical reasons.

PNAS: Fracking Contaminates Groundwater

Many people have been pushing natural gas as the fuel of the future. Less polluting than oil or coal, the only thing holding gas back has been supply, causing a scramble for new gas fields using the latest drilling techniques. The conclusion of a new study, published in the Proceedings of the National Academy of Sciences, is that drilling for natural gas in shale formations, using the process known as fracking, has seriously contaminated shallow groundwater supplies beneath Pennsylvania. Duke University scientists sampled well water across 175 kilometers of far northeast Pennsylvania centered on the town of Dimock, made famous by the film Gasland. The analysis does not indicate how pervasive such contamination might be.

Ocean Sediment, It's A Gas

Methane is an important greenhouse gas, 30 times more potent than CO2, but our knowledge of the methane cycle is woefully inadequate. Sediments on the ocean's floor contain immense quantities of methane and there are enormous fluxes of methane into and out of these sediments. Trapped frozen in ice, there are some 10,000 gigatons of carbon stored under the sea—twice as much carbon as contained in conventional fossil fuel reserves. Some scientists consider the release of this methane the single worst environmental danger we face as a species. A massive release of ocean floor methane could cause real runaway global warming that would have dramatic impact on life. But methane continually leaks from seabeds around the world, contributing to the total amount of carbon injected into the ecosystem. A new report finds that ocean methane concentrations have been underestimated by a factor of 10 to 20 fold.

Researchers Say UN Climate Goals Impossible

International negotiators at a recent UN climate conference held in Bangkok repeated the demand that global warming this century be limited to no more than 2˚C. But while those attending the UN boondoggle stuck to the climate alarmist party line, results from a newly published Canadian government climate study concluded that “it is unlikely that warming can be limited to the 2˚C target.” The modeling based paper found that reaching the stated IPCC goal would require that greenhouse emissions “ramp down to zero immediately,” which means shutting down the global economy and banning the automobile. Moreover, starting in 2050 scientists would need to actively remove greenhouse gases from the atmosphere, requiring a rush to implement controversial and possibly dangerous geoengineering programs. Why does the global warming lobby continue demanding the impossible? Perhaps it is because global warming isn't about climate change at all.

A Wetter World During The Eocene

It is well known that water, H2O, is the single most important greenhouse gas. But water also plays a central role in determining the delicate balance of energy and mass that regulates the temperature of Earth. A wide range of predictions have been made regarding water in a warming climate, ranging from catastrophic droughts to increased monsoon rains and tropical storms. Conventional wisdom states that a warmer world is a wetter world. In a newly published paper in the journal Science, two researchers examine the Eocene (∼56 to 34 million years ago), looking for clues to the tropical climate–water relationship. Annual global temperatures during the Early Eocene Climatic Optimum (EECO) around 50 million years ago were as much as 12°C higher than modern values. The new results provide compelling evidence that the tropical engine of the water cycle was more active than predicted by current climate models.

Wind on the Water

The world's oceans represent the major source of stored heat energy that helps to mediate Earth's climate. The ocean surface boundary layer, where the ocean and atmosphere meet, heat is exchanged, as are gasses like CO2. The rate at which these exchanges take place has major implications for the mechanisms controlling climate change. A soon to be published paper in the journal Science documents a new study of the ocean surface boundary layer and, to the investigators' surprise, reveals that the rate of energy dissipation within the boundary layer to be enhanced by 10 to 20 times. This indicates that the atmosphere does not supply the energy for the boundary turbulence, the ocean does. This contradicts the prevailing scientific wisdom and shows once again that computer climate models are constructed using false assumptions.

What Caused The Spotless Sun?

Beginning in 2008, sunspots almost completely disappeared for two years. Solar activity dropped to hundred-year lows and the Sun’s magnetic field weakened, allowing cosmic rays to penetrate the Solar System in record numbers. More troubling, Earth's upper atmosphere cooled and collapsed by an unprecedented amount. Solar physicists openly wondered what was happening to our neighborhood star. Now, an international team of scientists funded by NASA claims to have figured out what was going on. Their explanation was just published in the March 3, 2011, edition of Nature.

Did Climate Change Make Us Human?

Given the ongoing controversy over global warming the question of whether humans can change Earth's climate is a familiar one. Lost in the fight over anthropogenic global warming is a more subtle and possibly more important question—how has climate changed people. In recent decades, the fossil record of hominin evolution and behavior, though still incomplete, has improved greatly. Triggered by a recent National Research Council (NRC) report, a perspective article in the journal Science poses the question, “did climate change shape human evolution?”

The Amazing Disappearing Gulf Oil Spill

Remember the 2010 BP Gulf Oil disaster? For 83 days it dominated news broadcasts in the US and was followed with interest around the world. Ecological activists wailed that the Gulf would never recover, alternative energy advocates demanded all off shore oil production be shut down, and the Obama administration quickly reversed its plans to open up more coastal areas for oil exploration. Now things have gone strangely silent regarding the worst ever US oil spill. A report commissioned by the reparations fund director pronounced Gulf fisheries mostly recovered and a number of scientific reports found that both oil and natural gas released by the spill had amazingly disappeared. Some environmentalists are still howling but the crisis seems to have passed much more quickly than even the most optimistic predictions.

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.

Melting Glaciers, Ice Caps and Sea-level Rise

Fluctuations in surface melting are known to affect the speed of glaciers and ice sheets, while the contribution of glaciers and ice caps to global sea-level rise is uncertain at best. Much has been made of the “accelerating” loss of ice from the Greenland glaciers. Over the past decade, Arctic sea ice retreated substantially during the summer months, and some predicted that the ice loss could be irreversible, a tipping point that would boost global warming. A number of new papers in Nature, Geophysical Research Letters and Nature Geoscience, shed new light on these subjects, and the answers are not the ones usually heard in the media.

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.

Precipitation, Convection & Climate Change

An increase in tropical storm activity has long been predicted as a harmful side-effect of human induced global warming. Hurricanes are to become more frequent and more deadly. All of this is predicated on the notion that a hotter climate will result in more moisture in the atmosphere and more frequent tropical storms. As it turns out, this is only half true. There may be more precipitation in the temperate zone, but an increase in tropical storms is not predicted—even by the IPCC models.
