A good friend who denies global warming, at least, did again in response to my facebook post linking to the NYTimes article about the truly frightening changes in CO2 in the atmosphere. I wrote this in response:
I think we should say climate CHANGE not warming. I think if you constructed a simple"biosphere" -- there's another name for it. We used to construct them in high school -- and then changed the composition of the gases in it you'd see what climate change means. It means that things can't live the way they do now, and some, perhaps not at all. It is such a thin layer of stuff that we survive in, so unusual. Why would we want to threaten it more than other forces of nature do? What if temperatures don't, on average, change, but fish are wiped out from their homes, birds fall dead in some areas, butterflies don't make it to Michoacan. There is a beautiful short film with various people who have seen earth from space speaking here: http://vimeo.com/55073825# I really think it might sway you a bit.
