AGW

We're Still Standing

A study of ancient volcanic ash found at key archaeological sites across Europe suggests that early modern humans were more resilient to climate change and natural disasters than commonly thought. The study, which appeared in PNAS, analyzed volcanic ash from a major eruption that occurred in Europe around 40,000 years ago. The volcano spewed so much ash that the event probably created winter-like conditions and a sudden colder shift in climate. Scientists have generally suggested that the spread of modern humans, and the decline of our cousins the Neanderthals, was primarily due to ancient volcanic eruptions and deteriorating climate conditions, but this study shows that stone-age man rolled with the punches and shrugged off the sudden shifts in climate. This new evidence flies in the face of modern predictions that a shift of a few degrees in average yearly temperature will decimate human populations world wide.

Sense and Sensitivity

One of the main problems with the “theory” of anthropogenic global warming is its reliance on rising atmospheric CO2 levels to force a global rise in temperature. This is predicted by climate change proponents by running large, complex computer models that imperfectly simulate the physics of Earths biosphere: ocean, land and atmosphere. Central to tuning these general circulation models (GCM) is a parameter called climate sensitivity, a value that purports to capture in a single number the response of global climate to a doubling of atmospheric carbon dioxide. But it has long been known that the Earth system is constantly changing—interactions shifting and factors waxing and waning—so how can a simple linear approximation capture the response of nature? The answer is, it can not, as a new perspective article in the journal Science reports.

Why Are Sea Levels So Low?

The last interglacial period (LIG)—the Eemian—is commonly believed by scientists to have been warmer than the current Holocene interglacial. Along with that balmier climate there is evidence that sea levels were significantly higher than today. Previous studies have pegged Eemian sea levels at 4 to 6m higher than today. Recently, a new investigation raises that estimate, reporting that ancient sea levels peaked between 6.6 and 9.4 m (~20 to 30 feet). Modern day accounts of flooding in low lying coastal areas and tropical islands abound, with ominous suggestions of links to global warming. How high the oceans will rise is a topic of debate for IPCC members, the news media and assorted climate alarmists, but they are asking the wrong question. Instead, they should ask why are sea levels so low?

The Once & Future Climate?

Between 15 and 20 million years (Myr) ago, Earth's climate took a pause during its long slide into the Pleistocene Ice Age for a period of real global warming. During this relatively brief time glaciers around the world retreated and there are indications that, at least around the edges of the continent, there was significant vegetation on Antarctica. Temperatures may have been as high as 11°C higher than today. Scientists say this global warm spell took place under under CO2 levels in the range of 190–850 ppmv, both significantly higher and lower than today's 390 ppmv. It is hoped that studying conditions during the Miocene warming can provide constraints on the fundamental laws governing the climate system. Why? If the Pleistocene Ice Age is truly coming to an end, as some have said, this may be the climate of the future.

Desperate Climate Scientists Blame Bad Weather On Global Warming

After decades of debunking and statements by responsible scientists that climate is not weather and individual anomalies are not an indication of climate change, the government funded IPCC lackeys at the UK's Met Office and America's National Oceanic and Atmospheric Administration have publicly attributed recent bad weather events to man-made climate change. These irresponsible boffins' shrill claims illustrate the desperation in the anthropogenic global warming (AGW) camp in the face of declining public concern over climate change. While admitting that it is impossible to blame a single event on global warming, climate alarmists are claiming attribution is possible as long as it is framed in terms of probability. They have gone from lies, to damn lies and now, finally, to statistics.

Ravaged Reefs Rebound

In a new study of coral reefs off the Pacific coast of Panama, a team of scientists has discovered something shocking: those seemingly thriving, permanent reefs have undergone widespread devastation in the past. Even more shocking was the realization that, despite this natural destruction of coral reefs, the reefs bounced back—after laying dormant for 2,500 years. We have been told that the oh so sensitive coral reefs of the world are all going to die if the world's temperature rises due to that horrible man-made scourge, global warming. Yet it seems that nature has been happily wiping out and re-establishing reefs across all the oceans of the world since before the rise of human civilization. Once again the warmists' scare tactics founder on the reefs of actual science.

New Climate Models Fall Short

The IPCC is working up to releasing pieces of its next climate report, starting in 2013. This has the world's climate scientists scrambling to get their latest work included in that dubious document. Foremost among those struggling for primacy of place are the computer modelers, those who study their own created worlds instead of the natural one around them. This report promises to be more contentious than the last one (AR4) in that the modelers have been racing to incorporate the effects of aerosols, soot and other airborne particulates that had previously been give scant attention. Early results suggest that aerosols have a much greater impact on regional climate than scientists had realized and that aerosols and clouds are providing some big surprises.

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.

The Immorality Of Climate Change

After decades of trying to argue the case for catastrophic human caused climate change, aka global warming, based on its scientific merits, AGW proponents are now shifting their focus to a more abstract argument. Instead of trying to establish a causal relationship between human CO2 emissions and the planet's modest warming trend, the new tactic is to re-brand global warming as a moral dilemma. Because the perceived problem is global in scope and the science so tentative, the result of the debate so far has been distributed blame and inequitable impact on the world's poor. According to a new book, this leads to a kind of moral corruption where we let ourselves be persuaded by weak or deceptive arguments, with disastrous consequences for our ability to act on climate change. Can not acting in response to wild speculation based on incomplete science be immoral? Can actions based on a lie be moral?

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.

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.

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.

Hurricane Prediction Hokum

Things have settled down a bit since the climate research scandals of early 2010, and some of the crew at the Met Office Hadley Centre have put forth a new paper. In it they claim the ability to “skillfully” predict hurricane activity for several years in advance. This seems a useful and more reasonable thing for this bunch to be doing, as opposed to scaremongering about anthropogenic global warming, but there is a catch. As it turns out, the whole exercise is aimed at blaming a purported increase in hurricane activity on global warming—the climate change scam lives on.
