Just saw this film for the first time, pretty good film I think.
For those of you who haven't seen it and don't know much about global warming, then you should take a look at it, and even if you know a little about global warming you should take a look at it, it is a good gatherer of facts (has a few political issues in it, but what do you expect?).
There were a few things in there that I did not know before, some minor details like the investigation that Dutch scientists made into birds hatching their eggs and caterpillars coming out for the summer, it seems that the caterpillars are coming out earlier each year, they used to come out at the same time the chicks hatched and provided a good source of food for them and now are too big or something for the chicks to eat, at least some bird species seem to be suffering from lack of food in Holland (and this can be attributed to global warming since the caterpillars get out earlier because it gets warmer earlier).
Anyways, if you haven't seen this film, go see it, rent it or something, download it from Bittorrent, do whatever, just see it.
