Is Snow a Sign of Global Warming?

Scientists are actually finding that snowstorms could be one of the signs of global warming.

| January 8, 2010

Recent heavy snowstorms and cold weather have prompted some commentators to suggest that a cold winter proves global warming isn’t really happening.

Don’t let those naysayers snow you. 

A few snowstorms, cold snaps or even heat waves do not prove anything about climate change, because there is a significant difference between weather and climate. Weather is what we experience on any given day or even over a couple of weeks. Climate describes a region’s prevailing conditions — including such things as temperature, rainfall, wind, humidity and atmospheric pressure — over long periods of time. Climate is a good indicator of what to expect. For example, in the Midwest, one would expect cold winters, whereas in a Mediterranean climate, one would expect a generally milder winter.

Climate change refers to shifts in prevailing conditions observed over decades. One such shift is a long-term rise in global average temperatures. The current cold spells are occurring against this backdrop.



Putting aside the difference between weather and climate, climate change projections show that a warming planet generates more precipitation in areas that typically experience rain or snow. Rising ocean surface temperatures already have increased the temperature and moisture content of the air passing over the United States, setting the stage for heavier snow and rainstorms. An Intergovernmental Panel on Climate Change report found that global warming has increased the frequency of storms that dump heavy precipitation over most land regions that experience storms. Most deserts, conversely, are getting drier.  

“Climate scientists aren’t at all surprised that there are more drenching rain or blizzards in certain parts of the country,” says Dr. Brenda Ekwurzel, a climate scientist with the Union of Concerned Scientists (UCS). “That’s consistent with well-documented climate change trends over the past several decades. Unless we take some dramatic steps to curb global warming, we likely will see a lot more regional precipitation over the next few decades.”

sorry, to read about global warming on mother earth news. Why not the so called concerned scientific people tell ahead of time what will happen? So far the temperature and the effort to prove temp. rise is proving to be a mess; they have now moved to explaining 'weather' and 'climate'. The amount being spent on trying to keep the earth clean is eating into tax payers! and it is not helpful to mankind. Man need not try to be God through various government agencies under various names.

I can't believe that MEN readers still deny global warming. I hope that MEN will publish more articles on the subject as it is the most important issue facing mankind. http://climate.noaa.gov/index.jsp?pg=/education/edu_index.jsp&edu=literacy http://www.politifact.org/truth-o-meter/article/2009/dec/11/climate-change-e-mails-and-copenhagen/ http://americasclimatechoices.org/ http://www.aps.org/about/pressreleases/climatechange08.cfm http://www.agu.org/sci_pol/positions/climate_change2008.shtml http://www.ametsoc.org/POLICY/2007climatechange.html http://www.epa.gov/climatechange/science/stateofknowledge.html http://www.globalchange.gov/ http://online.wsj.com/article/SB10001424052748703819904574551303527570212.html#articleTabs%3Darticle http://www.columbia.edu/~jeh1/ http://www8.nationalacademies.org/onpinews/newsitem.aspx?RecordID=11676 The IPCC is a scientific group.

I can't believe Mother Earth News still believes in global warming. Didn't you read the news stories about the emails the so called scientist sent? Haven't you read any of the real science? I live on the coast of California. Every few years it rains a lot. It always has! It is called weather cycles and is due largely from ocean temps and right now the water is cooler than normal. Then the storms move east across the mid-west and drop, ummmm, snow! It is not global warming. And quit with the name calling like naysayers and denier. Just because your science is junk crap doesn't mean you have to call names.
