Re: Catastrophe post
Your question:
shows a lack of background on the subject, which that hotlink to the left can remedy. It includes a lot of discussion about climate history besides the current urgent situation.
A plant, like all other lifeforms, is adapted to a particular environment and climate. The global change in CO2 level will not merely produce a greater average temperature but also a very different climate regime. Deserts and precipitation patterns will shift, which will seriously disrupt agriculture and local ecologies. Also, the rise in sea level and siltation patterns will have major impacts on coastal regions both above and below the water.
Most of what you read in newspapers and magazines about climate change is not hyperbole and fear-mongering, though in this case, I criticized one of my favorite magazines for presenting worst-case, but feasible, scenarios with more sensationalism and less nuance than I normally expect from that publication.
