Apparently according to the latest info (presented on a news channel) the earth as we now know it will be drastically different in 20 years time. ie new coastlines, hotter temperatures. They are painting a very bleak future unless we make drastic changes now. (This may or may not be 'old' news to you, but I don't watch the news. Too depressing.)
What do you think the earth will be like in 20 years time?
