SEARCH BLOG: GLOBAL WARMING
We were greeted by minus 25 degree (F) windchills as we stepped out of the Detroit airport terminal yesterday afternoon. Quite a change from the spring-like conditions of Florida. Fortunately, we had enough layers of outerwear to keep out the cold until we made it back to our vehicle.
But that got me to thinking about the consequences of climate change. Suppose for a second that there were no controversy about anthropogenic CO2 global warming and that the earth, for whatever reason, was warming. Would that necessarily be a bad thing?
It seems that for every bad scenario, there is an offset, or maybe even more than an offset, on the favorable side.
Certainly, milder winters that require less fuel for heating would be favorable... and even reduce the further growth in CO2 production from both heating and automobiles which are less fuel efficient in very cold temperatures. Certainly, longer growing seasons in North America, Europe and Russia would enable a greater diversification of crops and better support a growing population. Certainly, older people would be far less susceptible to deaths related to cold (which would at least offset deaths related to heat). Certainly, wild animals would have a greater survival rate in less severe winter conditions.The doomsday scenario of all of the polar ice caps melting and flooding coastal areas is a remote possibility in the next millennium, but there will still be a coastline. And Greenland could once again support agriculture and cities as it did with the Vikings a millennium ago.
So, yes, there might be change... but I'm not convinced that the change would be... by and large... unfavorable.
By the way, the actual temperature was -4 (F) this morning when I trudged out to get the newspaper... and my natural gas furnace is doing its best to warm the house, if not the environment. It may get all the way up to the low 20s by this weekend. This is the most prolonged cold period around here in years.
Come on global warming... or at least Michigan warming.
