I'm writing a story that set in the second half of the next century, but i think my questions are about real science. Lets suppose that current trends continue for a while, until either fossils depleted, or become unviable to use them, so for a few decades i guess. Is there significant chance, that ice disappears from North Pole, there wont be snow in North Europe? Any estimation how much could sea level rise? How could climate change affect Africa? http://news.nationalgeographic.com/news/2009/07/090731-green-sahara.html I hope this is a reliable enough link, it shows further sources, but if there is any problem with it, i try to find a better one.
