Global Warming Links

Via RealClimate I found this great link about The Discovery of Global Warming.

And, while looking for grass growing in Antarctica, I found this great site: Global Warming:Early Warning Signs.

There are two species of flowering plants in Antarctica: Antarctic pearlwort and Antarctic hair grass. Both have spreads dramatically in the last century:

The populations of two native Antarctic flowering plants increased rapidly between 1964 and 1990, coincident with the strong regional warming over the Antarctic Peninsula. The Antarctic pearlwort population increased 5-fold while the Antarctic hairgrass increased 25-fold. The unusually rapid increases are attributed to warmer summer temperatures and/or a longer growing season, which enhance the plant's ability to reproduce.
