I remember in the early 70's taking college classes in Environmental Science and Ecology. It was ground zero for early study of global warming. I had Earth Science professors teaching us how a 2 degree increase in average temperature on the west coast of Africa was affecting the strength of low pressure systems which ultimately turned into hurricanes. So we didn't create the problem, we started looking for ways to understand it. I'll get off my soapbox now. Only because I need to change the album on my turntable. Great article. I enjoyed it. Lee
