Unless you have been living in one of the few truly remote areas of the planet, you have been exposed to them. Climate change memes that pass from person to person and are repeated without thought or critical examination. They range from the subtle—bad weather is being increased by global warming—to the banal—over 97% of scientists agree about climate change. We are bombarded with these unsubstantiated ideas over and over again, from talking heads on TV, newspaper headlines, our friends and even the president of the United States. They are blatant untruths that have become legitimized by repetition, until school children and adults alike patriot them to each other. The recent tropical cyclone, Haiyan, has triggered another round of meme infection: it was the worst storm in history, tropical storms are getting bigger every year, there are more storms every year, and, of course, they are all caused by global warming. Trouble is, these “facts” are all false.
The long awaited full text report is finally available. The Final Draft Report, dated 7 June 2013, of the Working Group I contribution to the IPCC Fifth Assessment Report Climate Change 2013: The Physical Science Basis was accepted but not approved in detail by the Twelfth Session of Working Group I and the Thirty-Sixth Session of the IPCC on 26 September 2013 in Stockholm, Sweden. This report consists of the full scientific and technical assessment undertaken by Working Group I. While the final draft of the underlying Working Group I report is still subject to copy-editing and corrections in proof as normally applied to scientific reports the fundamental tone and content of the report has been set. No screaming warnings; no predictions of impending doom. The most shocking thing is that our knowledge of climate change has not advanced in almost a decade. Simply put, climate scientists are puzzled by the way nature is acting.
In a mad rush to prove who can put out the most inane press release, various warm-mongers, news hacks and climate alarmists have gone on a predictable spree, trying to blame Hurricane Sandy and the resulting disaster in the US Northeast on CO2 levels. Who are these clowns? Even the IPCC issued a statement saying that global warming was not to blame. Have none of these empty headed blatherskites noticed that it has been more than seven years since a major hurricane struck the US, the longest such period since the Civil War? Evidently not, since they continue to spew unscientific twaddle and the news media continues to lap it up like a dog eating its own vomit.
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.
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.
With massive floods in Australia and Brazil, and bitter winter weather across the Northern Hemisphere, climate change alarmists have been quick to blame the severe weather on global warming. The fact that such weather is well within normal variation has not stopped the catastrophists from claiming vindication. No matter that those who study the Pacific and Atlantic decadal scale oscillations predicted a cold and snowy winter for Europe and North America, the recent blizzards are being offered up as “proof” that Earth's climate is changing for the worse. And what of the reports of widespread natural disaster from Rio, Brisbane and elsewhere? Even more global warming, of course. When it comes to wicked weather, the climate change cabal's misinformation machine is running at full tilt.
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.
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.
It is accepted that volcanic eruptions can have a major impact on short term climate. A new study in Nature Geoscience uses instrument records, proxy data and climate modeling to show that multidecadal variability is a dominant feature of North Atlantic sea-surface temperature (SST), which, in turn, impacts regional climate. It turns out that the timing of multidecadal SST fluctuations in the North Atlantic over the past 600 years has, to a large degree, been governed by changes in external solar and volcanic forcings. Solar influence is not surprising but the fact that volcanoes cause climate change lasting decades has some significant implications for those trying to model climate over the next century.
In an example of what Presidential Science Advisor John Holdren would label “global climate disruption,” a 2009 report claimed that warming surface water in the Pacific Ocean was having an impact on the frequency of tropical storms. Moreover, landfalls along the Gulf of Mexico coast and Central America were supposedly increased. Now a new study appearing in Geophysical Research Letters has found these claims to be untrue. It seems that there is little correlation between the Atlantic hurricane activity and Pacific Ocean warming. In fact, the increased tropical storm frequency in 1969 and 2004 can be readily explained by increased warmth in the Atlantic where the storms form. Once again, those looking for a smoking gun in the form of human caused climate change are forced to look elsewhere.
According to the AP, top researchers now agree that the world is likely to get stronger but fewer hurricanes in the future because of global warming, seeming to settle a scientific debate on the subject. But they say there's not enough evidence yet to tell whether that effect has already begun. Despite warnings by scientists that identifying an actual trend in storm variability is impossible due to a lack of reliable historical data, a new report in Nature Geoscience is being cited as a solid prediction of future trends in tropical cyclone activity. The other thing not mentioned is that this research is based on models of questionable accuracy.
The supporters of anthropogenic global warming (AGW) claim that they have science on their side. Time and again we are told that the debate is over, the science is settled and consensus among the world's scientists reached. If that is true, why are so many scientists coming forward to oppose and denounce the climate alarmist's theory? To understand the true nature of the climate change debate it is necessary to understand what a scientific theory is and how to judge a theory's validity.
Bleached and dying coral reefs are often held up as proof that global warming is laying waste to Earth's ecosystems. Now come reports that a number of reefs around the world are being brought back from the dead by dedicated oceanographers and conservationists. “The results are more than just promising; they are beautiful,” says Baruch Rinkevich, a marine biologist at the National Institute of Oceanography in Haifa, Israel. But how can these reefs recover in the face on ongoing global warming? Either global warming has reversed course or the bleaching of reefs wasn't due to global warming in the first place.
The evidence is in, observations and models show that northern tropical Atlantic surface temperatures are sensitive to dust blowing in from North Africa. Regional changes in stratospheric volcanic and tropospheric mineral aerosols (i.e. dust) are responsible for 69% of the upward trend in temperatures over the last 30 years. Once again a new factor has been discovered that is not accounted for in general circulation models (GCM) used to predict global warming—and once again the importance of CO2 is diminished.
Most everyone has heard the recent announcement that Global Warming has been put on hold for 20 to 30 years. Earth's variable climate continues to make fools of climate scientists, obstinately refusing to follow the IPCC's climate change script. Why? Because the climate change doomsayers put their faith in computer models, not in hard science.
