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.
For decades the US government has funded research into “clean coal” technology. Billions of dollars have been spent with the only visible result being employment for a small army of government coal researchers and academics. Now scientists at Ohio State University have announced that, after 15 years of effort, they have produced a breakthrough—a new technology capable of turning coal green and carbon dioxide emission free. This was widely reported in the news media and passed practically without critical comment. Is it true? Is coal no longer the dirty, devil spawned fuel of evil industrialists everywhere?
Just when it seems that public figures can sink no lower, be more cynical, act more duplicitous, a news story comes along that plumbs new depths in ideological betrayal. And so it was this week when the shocked staff at Current TV was called to an all hands staff meeting. They were informed that the Current TV network, supposedly a bulwark of liberal green thought holding back the barbarian hoards from FOX and talk radio, had been sold to those leading mideast liberals at Al Jazeera. Former Vice President and self styled eco-prophet Al Gore has made himself a much, much richer man by doing what the political class has done since the dawn of human history—sell out to the other side.
Even though the Wind Production Tax Credit (PTC) may be extended when Congress reconvenes in a post-election, lame duck session, American wind turbine manufacturers are laying off workers right and left. Estimates from the Institute for Energy Research (IER) indicate approximately 3,000 jobs have already been cut or designated to be cut soon. That number is almost 30% of the 11,000 direct manufacturing jobs in the industry. At the same time, the European Union (EU) has launched an investigation of Chinese photovoltaics exporters. Similar charges in the US led to the imposition of preliminary anti-subsidy tariffs on China in March and preliminary anti-dumping tariffs in May. Instead of bringing promised prosperity to developed nations, the green energy industry is collapsing or fleeing to the developing world.
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?
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.
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.
Precaution is now an established tenet of environmental governance, law, and public policy at the international, national and local levels. When it comes to pollution, toxic chemicals, genetically modified organisms, endangered species and climate change, the so called precautionary principle has become the guiding doctrine for timorous souls everywhere. But more than that, it is a codification of the idea that before anything new is allowed, it must be proven, beyond a shadow of a doubt, to cause no harm to anything in anyway, under any conditions, anywhere—period. It is “look before you leap” on steroids and a major legal weapon used by environmentalists and neo-Luddites everywhere to hamstring human progress. Raising angst to an art form, progress hating activists have managed to block needed energy and industrial expansion at a critical time in humanity's development.
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.
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?”
Climate change activists have long warned of a bleak and impoverished future due to the ravages of global warming. But evaluating the effects of climate change in the long term is an extremely complex issue. There are no reliable, accurate predictions for future climate, demographic change, economic development, or technological progress. A new study in the Proceedings of the National Academy of Sciences (PNAS) finds that if the climate of the 2080s were to occur today, the annual loss in household welfare in the European Union (EU) would range between 0.2–1%. Furthermore, this minuscule change was derived using aggressive IPCC scenarios for temperature and sea-level rise. Regardless of the claims made by climate change doomsayers, the future is not going to suck after all.
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.
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.
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.
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.
