Global Warming from ScienceDaily

http://www.sciencedaily.com/news/earth_climate/global_warming/ is a web site with nearly daily news about Global Warming. If anyone reading this knows of a site that lists the Global Warming antagonists, I'd like to list them here. Often (always?) they choose names that would allow the reader to "ass"ume that they are just the opposite: sites like this one that assume the global warming debate is over and the only questions are, where do we go from here? I know, for example, that there is a site that I thought might have been backed by BP Oil, not sure, but it talks about the good things Global Warming will and/or is doing for Canada. Surely a warmer Canada must be a good thing as vegetation and animal species continue their march northward. Right? Well, it doesn't take a Ph.D. in ecology to know that the earth is made up of ecosystems, and by definition any warming of Canada will mean a change to its ecosystems. (Moving to Georgia from Ohio has shown me an example of this unrelated to Global Warming: Kudzu (see below).) Speaking of ScienceDaily:
Researchers have long debated the consequences of introducing non-native species into ecosystems. Recently, these debates have centered upon the effects of invasive exotics, and dramatic pictures of grasslands filled with leafy spurge, water pipes clogged by zebra mussels, and forest trees killed by kudzu vines have fostered the public's understanding of the issue. But now, two Canadian scientists are suggesting that even the introduction of some less aggressive species may have far-reaching negative repercussions.

Interestingly, it turns out Kudzu (a vine that was introduced in Georgia to help control soil erosion) is falling victim to a new disease that also affects farmers' crops in the southeast United States: Asian Soybean Rust Disease. Note, there is nothing here intended to link this disease to Global Warming, but to publicize the parallel changes in ecosystems as the climate changes.
