Global warming has many effects, like colder winters in certain parts of the world. How about tornados in february, thats a new deal. We can poo-paw it all we want but it is here and it will not get better by it's self. Can we stop it, I doubt man has the will to curtail his life style untill he is forced to. All you nay sayers might want to help your children move to higher ground before you pass on If you live on the coast. Do I know what will happen, Hell no, I live at 2600 ft. altitude, I doubt it will affect me, but you guys in Laguna beach and costal california might want to think about flood insurance. It will probably not happen in our lifetimes, but in a couple a hundred years, who knows.
