Also, 'cos of global warming the polar ice caps are melting, diluting the ocean meaning the conveyer belt that is the Gulf Stream is slowing down, which means less and less warm water is being brought up from the Carribean which is the only thing stopping us from being as cold as Moscow and Canada (same latitude you see). Soooooo... that means in a few years theres a very good chance of our winters being in the minus figures permanently, like in Moscow. That is, of course, unless we get hit my an asteroid before hand!
