http://www.scientificamerican.com/a...-climate-change-pause&WT.mc_id=SA_WR_20130904 From the 1940s through the 1970s there was no major warming trend in the average surface temperature of Earth. At the same time, the tropical Pacific Ocean, which is responsible for the weather patterns known as El Niño and La Niña that can swing global average temperatures by as much as 0.3 degree Celsius, was anomalously cold. For the past decade or so the tropical Pacific has again gone coldmore Niña than Niñoand a new study suggests that the phenomenon may explain the recent "pause" in global warming of average temperatures. Since 1998's record heat, average surface temperatures have plateaued for a decade or sofailing to reach new peaksalthough the decade also qualifies as the hottest on record. Rising concentrations of greenhouse gases in the atmosphere have not accelerated warming to new heights as rapidly as happened at the end of the 20th century. To explain this apparent hiatus, climate scientists Shang-Ping Xie and Yu Kosaka of the Scripps Institution of Oceanography at the University of California, San Diego, added the sea. Plugging in observed sea-surface temperatures as well as the more traditional numbers for the extra heat trapped by greenhouse gases into the U.S. Department of Commerces Geophysical Fluid Dynamics Laboratory computer model of the oceans and atmosphere might reveal if the cooler tropical Pacific was responsible for the climate change pause. By adding in the sea-surface temperatures of an oceanic area covering roughly 8 percent of the globe, the researchers were able to mimic the recent hiatus in global warming as well as weather phenomena like the prolonged drought in the southern U.S. The results are detailed in Nature on August 29. (Scientific American is part of Nature Publishing Group.) "The tropical Pacific is the engine that drives the global atmosphere and climate," Xie says. "There were epochs of accelerated and stalled warming in the past," including that pause in a global warming trend between the 1940s and 1970s, which has often been attributed to sunlight-blocking air pollution from Europe, the Soviet Union and the U.S. Whereas the largest ocean on a globe that is 70 percent water covered is an obvious driver of climate patterns, it is less clear what drives the cycles of cooling and heating of tropical Pacific Ocean waters. But it is clear that the cool Pacific pattern cannot persist forever to cancel out the extra heat trapped by rising CO2 concentrations, Xie notes. Clearly the climate scientists have been using the wrong assumptions all along if they are just now plugging in the temperature of the Pacific. And why does the U.S. Department of Commerce have a Geophysical Fluid Dynamics Laboratory? There was no warming from the 40s through the 70s which the scientists blamed on pollution blacking the sun light and what was the pollution? CO2. "The tropical Pacific is the engine that drives the global atmosphere and climate," Xie says. "There were epochs of accelerated and stalled warming in the past," Still they want to link present day the CO2 levels that are much different to the pre 40 levels. Since 1998's record heat, average surface temperatures have plateaued And they want the plateau to be the anomaly instead of the short worming periods that they admit was and is due to ocean temperatures. It looks like our Oriental scientists are looking to keep their jobs as the globe cools or doesn't boil away our oceans.
Earth to get too hot for human life... Sun’s heat will be too much for Earth in 3 billion years Fri, Sep 20, 2013 - Scientists have calculated when life on Earth must come to an end.
Uncle Ferd says, "Yea - the heat is on... Scientists more convinced mankind is main cause of warming 27 Sept.`13 - Leading climate scientists said on Friday they were more convinced than ever that humans are the main culprits for global warming, and predicted the impact from greenhouse gas emissions could linger for centuries.
