regarding 2012 and global warming

I believe that what we are seeing as per the global warming issue is a natural occurence, meaning that if we were to shut off all pollutants that go into the atmosphere every day we would still witness the natural occurences and changes that are happening today..true what we put into the atmosphere doesn't help and we should make a global effort to eliminate as much as possible. Nature regenerates itself on a continual basis such as a fire destroys most everthing in its path and within a short time later plants begin to sprout again. Could we have another ice age? Anything is possible. I try to look on the bright side and enjoy every day that I wake up, put my feet on the floor and watch a beautiful sunrise...
