oh for god sakes. now what? the scare factor has been pushed out since they cannot fit their models into the earth dieing in the next 50 years? So its year 3000 now.... why not send the Enterprise into the future and let them report back!!
and so....
Even if humans stop producing excess carbon dioxide in 2100, the lingering effects of global warming could span the next millennia. The results? By the year 3000, global warming would be more than a hot topic - the West Antarctic ice sheet could collapse, and global sea levels would rise by about 13 feet (4 meters), according to a new study.
Using a computer model, researchers looked at two scenarios - an end to humans' industrial carbon dioxide emissions by 2010 and by 2100 - stretched out to the year 3000.
Even if humans were to stop emitting excess carbon dioxide - or if they figured out a way to completely capture it - the effects of global warming would continue to accumulate. That's because previously emitted carbon dioxide lingers in the atmosphere and the oceans, unlike land, warm only gradually, according to one of the study researchers, Shawn Marshall, an associate professor of geography at the University of Calgary.
The carbon dioxide legacy
A number of gases contribute to global warming, among them carbon dioxide, methane and nitrous oxide. The study focused on carbon dioxide, because it is the principal greenhouse gas, and it can linger in the atmosphere for centuries, according to Marshall.
"Some of the carbon dioxide going into the atmosphere this century will be there still 1,000 years from now," he said.
Marshall, lead researcher Nathan Gillett of the government agency Environment Canada, and their colleagues found that, by the year 3000, the brunt of the changes occurred in Southern Hemisphere. Not surprisingly, the 2100 scenario yielded more extreme results. In particular, the model predicted that southern oceans - the combined South Pacific, Atlantic and Indian Oceans, where the Antarctic Circumpolar Current resides - would warm considerably, with some far-reaching results.
