I don't have to tell you that the fire in and around Fort McMurray in Alberta has been in the news the past couple of weeks. The scenes have been unbelievable. Many scientists think that global warming is a major factor in these fires, particularly in the Northern Hemisphere, where temperatures have been rising (recent temperatures in Alberta have been 30 degrees above normal) trees are drying and snow is melting earlier.
In Russia, about 70 million acres burned in 2012, much of that in isolated areas of Siberia. Alaska had its second-largest fire season on record in 2015, with 768 fires burning more than five million acres.
