What’s going on? Suddenly there are scientists willing to take a step back from the position that it is global warming that is causing the record cold temperatures across the nation. It couldn’t be because thus far in February, this is the third coldest winter in more than one hundred years, could it?
I mean, come on; as reported here, just this past Thursday on CBS This Morning, host Charlie Rose heard Michio Kaku, a physics professor from New York City College, become the latest scientist to claim that global warming was responsible for the bitter cold, saying, “What we’re seeing is that the jet stream and the polar vortex are becoming unstable. Instability of historic proportions. We think it’s because of the gradual heating up of the North Pole. The North Pole is melting. That excess heat generated by all this warm water is destabilizing this gigantic bucket of cold air… So that’s the irony, that heating could cause gigantic storms of historic proportions.” Rose agreed that the cold was indeed the result of global warming.
But then the New York Times published a piece quoting five leading climate scientists, John M. Wallace at the University of Washington, Isaac M. Held at the Geophysical Fluid Dynamics Laboratory, David W. J. Thompson at Colorado State University, Kevin E. Trenberth at the National Center for Atmospheric Research, and John E. Walsh at the University of Alaska, Fairbanks, who had written something quite different from the global warming devotees screaming the sky is falling because of global warming causing the cold weather. They wrote:
As climate scientists, we share the prevailing view in our community that human-induced global warming is happening and that, without mitigating measures, the Earth will continue to warm over the next century with serious consequences. But we consider it unlikely that those consequences will include more frigid winters … Sea-ice losses during late summer may indeed lead to regional changes in Arctic climate. But tremendous natural variability occurs in the large-scale atmospheric circulation during all seasons, and even in summer the links between Arctic warming and mid-latitude weather are not supported by other observational studies. The lag between decreases in sea ice extent during late summer and changes in the mid-latitude atmospheric circulation during other seasons (when the recent loss of sea ice is much smaller) needs to be reconciled with theory.
Do they mean that the global warming hysteric neurotics should take a chill pill? It’s about time.
