Joe Romm assumes what he has to prove -- and his assumption is wrong

As we all know, ANY weather event proves global warming.  Global warming is unfalsifiable and is, as such, a religious faith, not a scientific finding. So it is no surprise that Joe Romm, the professional Warmist, has put up an argument  -- excerpt below -- to say that the recent winter storms in the N.E. USA are caused by global warming.  But how can they be?  There has been no statistically significant global warming for 18 years or thereabouts.  But Romm writes as if warming were happening.  He assumes what he has to prove. Clearly, all the events he describes are natural and nothing to do with our static climate

Another epic blizzard is bearing down on New England. There is a “big part” played by “human-induced climate change,” especially warming-fueled ocean temperatures, according to Dr. Kevin Trenberth, former head of the Climate Analysis Section at the National Center for Atmospheric Research.

I asked Dr. Trenberth to comment on the role climate change has on this latest storm, which is forecast to set records. He explained:

    "The number 1 cause of this is that it is winter. In winter it is cold over the continent. But it is warm over the oceans and the contrast between the cold continent and the warm Gulf Stream and surrounding waters is increasing. At present sea surface temperatures are more the 2F above normal over huge expanses (1000 miles) off the east coast and water vapor in the atmosphere is about 10% higher as a result. About half of this can be attributed to climate change".

Before this latest storm, we’ve seen a long-term pattern of more extreme precipitation, particularly in New England winters. Climate scientists had long predicted this would happen in a warming world.

Like a baseball player on steroids, our climate system is breaking records at an unnatural pace. And like a baseball player on steroids, it’s the wrong question to ask whether a given home run is “caused” by steroids. As Trenberth wrote in his must-read analysis, “How To Relate Climate Extremes to Climate Change,” the “answer to the oft-asked question of whether an event is caused by climate change is that it is the wrong question. All weather events are affected by climate change because the environment in which they occur is warmer and moister than it used to be.”

One of the most robust scientific findings is the direct connection between global warming and more extreme precipitation or deluges. “Basic physics tells us that a warmer atmosphere is able to hold more moisture — at a rate of approximately 7 per cent increase per degree [Celsius] warming,” as the U.K. Met Office explained in its 2014 update on climate science. “This is expected to lead to similar percentage increases in heavy rainfall, which has generally been borne out by models and observed changes in daily rainfall.”

This means that when it is cold enough to snow, snow storms will be fueled by more water vapor and thus be more intense themselves. So we expect fewer snowstorms in regions close to the rain-snow line, such as the central United States, though the snowstorms that do occur in those areas are still likely to be more intense. It also means we expect more intense snowstorms in generally cold regions. This may appear to be counterintuitive — and certainly climate science deniers like to play up big snowstorms for that reason. But the fact is that the warming to date is not close to that needed to end below-freezing temperatures during midwinter over parts of the globe like New England, while it is large enough to put measurably more water vapor into the air.
