I can remember learning about the potential impact of global climate change back when I was a kid. This video talks about what we knew some 30 years ago in 1982 and how a lot of what was predicted has come to pass. A lot of folks seem to think that warnings about global climate change are something relatively recent, but we’ve known about the potential of this problem for a very long time. Unfortunately, by the time the evidence is clear enough for the deniers to accept it’ll be too late to do much about it other than try and cope with it as best we can. It’s going to get a lot worse before it gets better and a lot of people are going to suffer unnecessarily because we haven’t addressed the problem.
