What they are doing is moving from global warming to climate change to all pollution is bad. As the good book says there is nothing new under the sun and we are fixing to have the whole Rachel Carlson Silent Spring experience again. I think they will keep hammering the CO2 thing for the forseable future but use that as an entry into the whole man bad because he pollutes the planet thing once again.
That is exactly what many Republicans were doing on the campaign trail last fall. They drove me Nuts! "Well... we don't know if it's real... but let's just throw all this money at it anyway because the worst that can happen is we'll have a cleaner world."
ARGHHHHH!!!!
