First... take it easy with the alarmism. The Permian-Triassic extinction event managed to wipe out nearly 95% of life, and this was with a meteor, extreme ocean acidification, and extreme ice ages/drying of the land. Global warming, per se, at the extent we claim to have observed it, will not manage the same; in fact, likely it will help, as biodiverse areas spread northwards/southwards.
Second... certainly environments and habitats are at risk, I never will dispute this fact. But AGW, if it exists at all, is a threat eclipsed by deforestation, bottom trawling, direct persecution, etcetera regarding its ability to cause harm. Global warming catastrophism distracts people from real problems happening right now; not to mention lining its leaders' pockets.
Thirdly... and again, global warming has happened in the past few thousand years, two periods that spring to mind are the Medieval Warm Period and the Holocene Maximum, that were both 1) warmer than now and 2) failed to extinguish any known forms of life.
Fourthly... it's so easy to talk about change when one lives in a developed country and hardly has to give up any of one's possessions or luxuries to "change". Try telling the same to, for instance, an African who is barely able to feed his family, let alone sit at a computer or buy an iPod.
So basically... alarmism doesn't help anyone. Except perhaps Al Gore and western governments, who make massive amounts of green.
Wow, you know SO little about natural systems. Your statement opened my eyes like a slap across the face. Yes, there will be a minute amount of poleward vegetation shifts, BUT, just because it is more hospitable N or S due to temperature, plants can't simple move on in.
You see plant communities are HIGHLY attuned to the places they live in, beyond the ambient temperature they are dependent on Soil Type, Exposure, Humidity, Nutrient Types, Altitude, on and on and on and on. Temperature is just ONE of MANY ingredients that make a plant or community of plants survive.
Um, your right there are lots of other problems atm, but please notice you are trying to dim the lights on how humans may be impacting the atmosphere and there fore the climate. Who is making money off global warming? How are our leaders lining their pockets? I hear this all the time but I still have seen no examples.
Well humans were also not around to so drastically change the face of the earth and the atmosphere it lives in.
Thank god for that because it is the DEVELOPED countries that NEED to do the most changing.
