Winter Sun

The impact of solar irradiance variations on Earth’s surface climate has been debated by many in the past. Based on correlations between solar variability and meteorological changes, the Sun-climate link seems obvious but, as is often stated, correlation does not prove causation. Previously, any link was disputed because the amount of energy delivered by the Sun was deemed too small to have a significant impact. New satellite measurements indicate that variations in solar ultraviolet irradiance may be larger than previously thought, forcing a reevaluation of the impact of solar variation. A recent report in the journal Nature Geoscience claims to show just that—a link between the 11 year solar cycle and Northern Hemisphere winters.

Europe's CO2 Airline Armageddon

Starting on January 1, 2012, airlines flying to and from airports in the European Union (EU) will be forced into an emissions trading system that attempts to regulate CO2. The announced intention of this draconian cap-and-trade system is to save the world from the imagined ravages of anthropogenic global warming (AGW), but given the dire financial straits much of Europe finds itself in there is little doubt that Eurocrats will view this new policy as a potential source of revenue. Unfortunately, the new regulation threatens the entire structure of international air travel by unilaterally violating agreements that have been negotiated over decades. In seeking to avoid the imaginary dangers of global warming, the EU threatens the global air transport system with a very real CO2 Armageddon.

Scry Me A River

Nostradamus, the famous prognosticator, was said to have received his visions of the future by scrying—staring into a pool of ink for hours on end. The climate science equivalent of a gazing pool is the computer climate model, huge collections of complicated computer code that supposedly crank out frightening visions of the future. Most of the discussion about climate change has centered on the global aspects of the anthropogenic global warming (AGW), but now a number of climate mystics are turning their modeling dark arts to doing regional predictions. Why? The better to frighten the public and elicit funding from government coffers. Unfortunately, as climate researchers struggling to sharpen their fuzzy picture of what the future holds one fact has been ignored—there is even more uncertainty in regional models than in the global ones.

A Walk In The Clouds

Given that the Sun powers Earth's climate system and provides the energy for all life on our planet, it should come as no surprise that changes in solar activity can affect climate conditions. Because total solar irradiance varies only slightly, climate scientists have discounted our variable star as a driver of climate change. At the end of the 20th century, Heinrich Svensmark, of the Danish Space Research Institute, and Eigil Friis-Christensen proposed that solar activity may be a controlling factor for climate by changing low level cloud cover. Not surprisingly this idea was disparaged by mainstream climate science, since it would diminish the importance of greenhouse gases, CO2, the IPCC's favorite daemon, in particular. Now, after several years of experimentation at CERN, the preliminary results are in and it looks like Svensmark and Friis-Christensen were right after all.

Climate Science's Tangled Web

Recent days have seen a number of announcements about our changing climate. As it turns out Arctic ice is rebounding, sea levels are dropping and things just are not going according to the IPCC's plan for catastrophic global warming. Faced with reversal after reversal, it might seem logical for mainstream climate scientists to admit that they are wrong, that global warming is not taking place at a breakneck pace, but this has not happened. Instead, climate change apologists are weaving a tangled web of excuses—hot is cold, wet is dry, up is down. No matter what happens to the world we live in, the root cause according to the doomsayers is always the same: it's always global warming's fault.

Himalayan Glacier Disappearance Overstated

A pair of researchers has published a new report in the Proceedings of the National Academy of Sciences (PNAS) in which two out of three glaciers studied were disappearing. In a report that was edited by James Hansen, of the Goddard Institute for Space Studies, it would appear that the glaciers of the Himalaya are melting rapidly, but that is not how the report ends. The authors state that poor selection of study sites have led to the widespread use of non-representative data. Moreover, the IPCC report and others overstate the disappearance of Himalayan glaciers.

Climate Models Fail To Predict Past Catastrophes

Most people fall into one of two categories when it comes to predictions of future climate calamities: they either do not realize that the predictions are predicated on computer models or they unquestionably trust the models to reveal the future. A clear and lucid online article in Nature Geoscience addresses the current state and limitations of climate modeling. The article points out that State-of-the-art climate models are largely untested against actual occurrences of abrupt change. “It is a huge leap of faith to assume that simulations of the coming century with these models will provide reliable warning of sudden, catastrophic events,” the author states. To counter claims of predicted “tipping points,” incidents of abrupt climate change from the past are examined—incidents that current models get wrong.

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.

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.

The Price of Biodiversity

There has been a resurgence of alarmist claims regarding the pending extinction of a majority of Earth's lifeforms due to human misdeeds—clearing rain forests, polluting the oceans and, of course, causing global warming. Perennial crank and misanthrope E. O. Wilson leads the parade of doomsayers, claiming that biodiversity is dropping and a sixth major extinction event is just around the corner. What evidence backs these claims? Why, computer model projections, naturally. The facts are researchers have identified 1.4 million animal species so far, and recently a pair of Brazilian researchers estimated that there are estimated 5.4 million yet-to-be-discovered animal species alone. The truth is, scientists have no idea how fast biodiversity is falling because they have no idea how many species there are on Earth. And the researchers put a price tag on finding out that is simply stunning.

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.

Attack of the Climate Change Lawyers

One indication of how mature a scam has become is when it starts to attract the attention of trial lawyers. The recent spate of natural disasters has reminded people everywhere of how capricious the forces that govern our world can be. Floods in particular have destroyed crops, houses and lives in Australia, Pakistan, China and Brazil. While climate science remains too immature to blame humans for exacerbating the forces of nature by emitting greenhouse gases, there are ominous signs that climate change alarmists are becoming desperate enough to enlist the unholiest of allies in their cause—lawyers. An editorial in the February 20, 2011, edition of Nature Geoscience cites two new studies which claim to affirm the anthropogenic global warming/extreme weather link, opening the door for future litigation.

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.
