There is quite a collection of denier cult retards on this forum. Too bad you dingbats are so freaking ignorant and clueless about all this. Maybe if you all weren't as dumb as a bag of retarded rocks and had some education beyond the fourth grade, you wouldn't be such foolish dupes of the fossil fuel industry. Your denial of reality and scientific evidence is really pathetic.
Scientists are starting to look more closely at the long range effects of rising CO2 levels/global warming/climate change beyond just the end of the 21st century. If we continue with a 'business-as-usual' course, the results are extremely disastrous for mankind and all of the other life forms sharing this planet with us.
Climate change could make half the world uninhabitable
Climate change could make half of the world uninhabitable for humans as a rise in temperature makes it too hot to survive, scientists have warned.

Researchers from the University of New South Wales in Australia and Purdue University in the US said global warming will not stop after 2100, the point where most previous projections have ended. In fact temperatures may rise by up to 12C (21.6F) within just three centuries making many countries into deserts.
The study, published in the prestigious journal Proceedings of the National Academy of Sciences, said humans will not be able to adapt or survive in such conditions. Professor Tony McMichael, one of the authors, said if the world continues to pump out greenhouse gases at the current rate it will cause catastrophic warming.
"Under realistic scenarios out to 2300, we may be faced with temperature increases of 12 degrees or even more," he said. "If this happens, our current worries about sea level rise, occasional heatwaves and bushfires, biodiversity loss and agricultural difficulties will pale into insignificance beside a major threat - as much as half the currently inhabited globe may simply become too hot for people to live there."

But he said there was a good chance temperatures could rise by at least 7C (12.6F) by 2300, that would also make much of the world inhabitable.

"It needs to be looked at," he said. "There's not much we can do about climate change over the next two decades but there's still a lot we can do about the longer term changes."

They urge instead the use of carbon tax revenue to develop technologies that can supply clean energy to everyone and provide 'human dignity'.

An adaptability limit to climate change due to heat stress

Abstract
Despite the uncertainty in future climate-change impacts, it is often assumed that humans would be able to adapt to any possible warming. Here we argue that heat stress imposes a robust upper limit to such adaptation. Peak heat stress, quantified by the wet-bulb temperature TW, is surprisingly similar across diverse climates today. TW never exceeds 31 °C. Any exceedence of 35 °C for extended periods should induce hyperthermia in humans and other mammals, as dissipation of metabolic heat becomes impossible. While this never happens now, it would begin to occur with global-mean warming of about 7 °C, calling the habitability of some regions into question. With 11–12 °C warming, such regions would spread to encompass the majority of the human population as currently distributed. Eventual warmings of 12 °C are possible from fossil fuel burning. One implication is that recent estimates of the costs of unmitigated climate change are too low unless the range of possible warming can somehow be narrowed. Heat stress also may help explain trends in the mammalian fossil record.
