Global Warming Links
grass growing in Antarctica, I found this great site: Global Warming:Early Warning Signs.
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.
