Bucking the conventional feeling this winter, I have been loving all of this snow — this is how every winter should be! Avid cross country skiers everywhere agree.
Lest the record snow and polar vortexes (vortices?) distract us, or worse, make us wonder how we could be in the grip of global warming, take a look at the latest
New York Times article on the topic.
The article describes the alarming long term trends in snowfall and snowpack worldwide, and it reminds us all that, taken alone, local weather events on any given day or month cannot support or refute global climate change.
Among many alarming trends the article points out is that Europe has lost half its glacial ice since 1850; 2/3’s of Europe’s ski resorts could be closed by 2100; and the American West may lose 25 to 100 percent of its snowpack by then.
In the Great Lakes region, the number of days with snow cover has decreased by 5 days per decade, since 1975. The average snow depth has also decreased. Future projections predict later arrival of winter and earlier arrival of spring resulting in more precipitation falling as rain than snow (GLISA, Climate Change in the Great Lakes Region).
Of course, global warming is not just about inconveniencing a bunch of skiers. Those winter snows provide drinking water for us all and drought protection for farmers and forests.
So, next time you curse the snow delaying your morning commute, think about the likely future if current trends continue, and when you eventually get to the office or other workplace, give your Senator or Representative a call.
