The members of Congress that have been bought and paid for by the fossil fuel industry love to make statements that are just unbelievably stupid. My favorite is when they say, "I'm not a scientist, but..." You really have to wonder what kind of mentality makes you stand in front of cameras and say that you're not a scientist, but you still know more about climate change than all of the climate scientists in the world combined.
The next best thing is when they say we shouldn't act because it is 'unsettled' what the outcome of climate change will be. Just how silly is that? The world is heating up and it is not working out well for us. So, is it going to cost us plenty, or is it going to cost us plenty-plus? That's what isn't certain. But, it is certain bad things will happen to us because bad things are already happening to us.
Here is an excellent article addressing the question of holding off due to "uncertainty." I particularly love the analogy of letting your children kick lions.Yeah, its uncertain what would happen, but are you going to let them do it?
The politicians really are showing they aren't scientists on this one. If they were, they would know that the science really is settled and the only uncertainty is whether climate change will be bad for us or if it will be really bad for us. Either way, we need to act.
