Chris and I just finished watching an Inconvenient Truth, the movie narrated by Al Gore. It's a nice, if somewhat simplistic, introduction to global warming. I recommend that you watch it if you haven't already. The website for the movie can be found here. After we watched the movie, Chris and I went through the list of ways to reduce our CO2 output that is provided on the website. We decided that we were doing well in some areas (such as reducing the amount of heat we use in our home and turning off electrical appliances) but could do significantly better in others (such as buying products with less packaging and driving our cars less).
There is a section at the end of the film that describes the consequences of an ice chunk the size of Greenland melting. I wish they had taken this discussion a bit further. I posted a picture of a map almost a year ago that shows the shape of the continents should the earth's oceans rise by approximately 20 feet (which would happen were Greenland to melt). Roughly 70% of our population (on earth) lives within this 20 foot zone. I don't know about you (and where you live) but all four of the states in which I've lived, including our current home, happen to be under water. Chew on that for a while.
