Looks like the climate change deny-ers are moving along to a new strategy. First, they said that climate change wasn't happening. Then they said that humans didn't cause it. Now, in the face of overwhelming evidence that bad things are happening, they're beginning to say that it doesn't matter if we try to do anything about it or not.
Besides the moral implications of not attempting to be responsible for cleaning up a mess that you created, you have to admire these people for being very creative. While looking like they are changing to accommodate to a new scientific reality, they manage to keep protecting the interests that got us into this pickle in the first place - the people with the money, predominantly the oil and gas industry. Very slick.
Change is not always progress, sometimes it's only adjustment to keep power relationships functioning the way that they are. (Are you listening Barak Obama?)
