[Warmist Borenstein]: Climate Change Study Ties Recent Heat Waves To Global Warming

WASHINGTON — The relentless, weather-gone-crazy type of heat that has blistered the United States and other parts of the world in recent years is so rare that it can't be anything but man-made global warming, says a new statistical analysis from a top government scientist.

The research by a man often called the "godfather of global warming" says that the likelihood of such temperatures occurring from the 1950s through the 1980s was rarer than 1 in 300...While his study was published online Saturday in the Proceedings of the National Academy of Science, it is unlikely to sway opinion among the remaining climate change skeptics.

Hansen hopes his new study will shift people's thinking about climate change and goad governments into action. He wrote an op-ed piece that appeared online Friday in the Washington Post.

Another upcoming study by Kevin Trenberth, climate analysis chief at the National Center for Atmospheric Research, links the 2010 Russian heat wave to global warming by looking at the underlying weather that caused the heat wave. He called Hansen's paper an important one that helps communicate the problem.

White House science adviser John Holdren praised the paper's findings in a statement. But he also said it is true that scientists can't blame single events on global warming: "This work, which finds that extremely hot summers are over 10 times more common than they used to be, reinforces many other lines of evidence showing that climate change is occurring and that it is harmful."

Skeptical scientist John Christy of the University of Alabama at Huntsville said Hansen shouldn't have compared recent years to the 1950s-1980s time period because he said that was a quiet time for extremes.

But Derek Arndt, director of climate monitoring for the federal government's National Climatic Data Center, said that range is a fair one and often used because it is the "golden era" for good statistics.

[Pielke Jr. comment] Hansen's use of science as a political fulcrum encourages over-the-top claims by scientists and an effort to squelch opposing voices.

Average Ice Extent Increasing Since 2005 | Real Science

The lowest January-July average ice extent was in 2006, with 2012 ranked third highest. The trend has been slightly upwards over the last seven years.

Every month we hear that 2012 is the record lowest, which leads us to the conclusion that using climate math, the sum of a large quantity of negative numbers is a positive number.
