The Basic Science Of Climate Change Is Undeniable
It’s not hard to have heat on the brain this summer, especially here in the United States. Since the government began keeping records in 1895, this June was the hottest June – 2 degrees Fahrenheit above the 20th Century average. The past six months have been the hottest first half of the year on record since 1895, and for the 12 month period ending June 30th, it was also the hottest year on record since the United States began keeping records. Given that this followed a record warm winter and that the last decade has seen a tie for the hottest year on record, climate change has once again become a topic of debate. That being the case, I thought I might review what’s often lost in discussions of climate change: the basic chemistry that underlies what we know about how it works.
