Maybe I am out of wack on this, but I know about the disasters in North Atlantic when it get a centigrade higher temperature than normal. The poison algae are killing fish stocks en mass. I personally think that the waters in reality are more unforgiving than the atmosphere. Only because it is not obvious for the naked eye, it does not certify it as a good idea.
Keith comment about balance is key on this issue. We do not have a good track record on natural balance in the air and water. This must be improved and a healthy respect for all environments developed.
