Green advocates and climate change alarmists alike insist that the world shift to using only non-polluting, renewable energy sources, and the sooner the better. What is seldom mentioned is the enormous cost of retooling the world's energy infrastructure to use intermittent, unreliable wind and solar energy. A recent two part paper, appearing in Energy Policy, makes a reasonable attempt at stating the requirements to fix humanity's fossil fuel addiction and go all green. The analysis found that, to provide roughly 84% of the world's energy needs in 2030, would require around 4 million 5 MW wind turbines and 90,000 300 MW solar power plants, with the remaining 16% coming from solar photovoltaic rooftop systems, geothermal, tidal, wave and hydroelectric sources. Some quick back-of-the-envelope calculations show why the world economy cannot afford to go totally green.
This coming Wednesday, March 9th, is Ash Wednesday, which marks the beginning of the Christian holy season of Lent. It is traditional for Christians to fast or give up certain food or drink during the 40 day run-up to Easter. Now it seems, in a bold move to remain relevant in these days of climate change anxiety, the United Church of Christ has suggested that believers go on a “Carbon Fast” for Lent. Ignoring organized religion's dismal record for divining scientific truth in the past, and being perhaps a bit envious of the evangelical zeal shown by global warming true believers, church leaders are urging Christians every where to help fight global warming by cutting down on CO2 emissions. Strange, we've never seen Jesus driving a Prius.
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?”
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.
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.
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.
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.
As public concern rises over the safety and ecological soundness of renewable energy sources like solar and wind, the nuclear power industry is quietly ramping up to build new, smaller types of reactors that can be deployed as sealed power units. Russia is moving ahead with plans to locate floating nuclear power plants along its northern coast and a French company has designed a small offshore nuclear power plant called Flexblue. At the same time, efforts by the US Department of Energy's Savannah River Site to host a range of proof-of-concept units from several vendors has run afoul of bureaucratic infighting. Around the world, nuclear power is progressing, while former nuclear technology leader America founders.
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.
This week we have a crank duet, provided by Chrysler CEO Sergio Marchionne and US EPA Administrator Lisa Jackson. The shakiest of America's three domestic car companies, Chrysler, and the US Government are teaming up to bring the world something nobody asked for—a non-electric hybrid mini-van. The company announced that it would partner with the US Environmental Protection Agency to build and test prototypes of a hybrid vehicle that accumulates energy not in a battery pack but by compressing a gas hydraulically. This could be final proof that both Chrysler and the EPA should be disbanded.
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.
Climate alarmists have been slow to learn that their over-reliance on computer models and unproven theories has harmed their public credibility. In an attempt to counter the richly deserved bad press that climate science has been garnering these days, a number of global warming true believers are trying a different, more fact based approach to scaring the public. One such attempt recently appeared in the journal Science—not as a paper describing original research but as a perspective article. In it, a Senior Scientist at the National Center for Atmospheric Research, in Boulder, Colorado, attempts to “weave together” some carefully selected “threads in the discussion of climate” to arrive at a very familiar and unconvincing conclusion.
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.
