Studies conclude climate change will cause less severe winters
The Washington Post

After two straight miserably cold winters in the East, the trendy explanation has been that climate change made them more extreme. But two new studies say not so fast, we should expect a warming climate to lead to a marked decrease in cold weather as time wears on.

The authors of two new studies, published in the Journal of Climate and the Bulletin of the American Meteorological Society (BAMS), ran computer model simulations and found winter temperatures should become less extreme and less variable as the Arctic heats up. They also say theory back up their findings.

“The results indicate that Arctic amplification of global warming leads to even less frequent cold outbreaks in Northern Hemisphere winter than a shift toward a warmer mean climate implies by itself,” the Journal of Climate study concludes.

The BAMS study makes the unusual move (for an academic paper) of citing and then refuting the remarks of a political figure, White House science advisor John Holdren. Holdren, following the vicious January 7, 2014 “polar vortex” blast in the eastern U.S., stated in a video: “…the kind of extreme cold being experienced by much of the United States as we speak is a pattern that we can expect to see with increasing frequency as global warming continues.” But a cold wave as powerful as the January 7, 2014 event will cease to exist by the end of the century, the BAMS study concludes.

En ce jour de la Terre, la bonne gauche va sans doute nous répéter que le débat sur le réchauffement climatique est clos et que la science est définitive. Or, comme cet article le démontre, il n’en est rien, il reste encore de nombreux point d’interrogation. Mais ça, les Québécois ne peuvent pas le savoir, car nos bons médias n’écriraient jamais un tel article.
