Scientists at the National Oceanic and Atmospheric Administration have demolished claims by global warming activists that global warming caused or worsened many extreme weather events last year.
According to NOAA’s new publication, Explaining Extremes of 2013 from a Climate Perspective, there is no discernible connection between global warming and 2013 extreme weather events such as the California drought, Colorado floods, the UK’s exceptionally cold spring, a South Dakota blizzard, Central Europe floods, a northwestern Europe cyclone, and exceptional snowfall in Europe’s Pyrenees Mountains.
he California drought provides a good example of global warming activists making false and irresponsible claims regarding global warming to deliberately mislead people who aren’t familiar with scientific studies and evidence. The liberal Center for American Progress and its media allies such as the Washington Post, San Jose Mercury News, Associated Press, and others have all published stories claiming global warming caused or worsened the ongoing California drought. Scientists, however, say just the opposite. “[F]or the California drought, which was investigated by three teams from the United States, human factors were found not to have influenced the lack of rainfall,”NOAA reported in an accompanying press release.?
Dr. Cullen also leads the World Weather Attribution program, an international coalition formed to quickly determine climate links to extreme weather events. “In some instances, scientists are now able to quantify the relationship between an extreme event and long-term warming trends, rather than consigning the public to reliance on dueling speculations not grounded in science,” she said.
The meteorological society reports do not sit well with some climate scientists who remain wary of trying to tie climate change to individual events. Michael E. Mann, a climate expert at Pennsylvania State University, said the current level of warming of about 1.5 degrees Fahrenheit around the globe (and somewhat more over North America and the Arctic) “has fundamentally influenced all meteorological events,” not just those that get written up in a study.
Dr. Mann said the work and the debate about it were useful. “If anything, this particular debate underscores that the question is no longer whether there is an influence of climate change on extreme weather events. The debate is simply over the magnitude and extent of that influence.”
