The odd thing is that where some people were initially concerned that Al Gore should not be a global warning expert because he is not a scientist, this is the reverse problem. Here it is James Hansen speaking outside his area of expertise.
He is a renown scientist, but he is not an economist or a legislator. I have always liked the way Senator Kerry has always spoken of the scientists' work and their conclusions, then spoke of his job as a legislator to write law that would be good policy. Here, Jansen is correct that ANY more carbon into the air is bad, but saying this shows he has no understanding of politics at all.
Tackling climate change does not allow room for the compromises that govern the world of politics, Hansen said.
"This is analogous to the issue of slavery faced by Abraham Lincoln or the issue of Nazism faced by Winston Churchill," he said. "On those kind of issues you cannot compromise. You can't say let's reduce slavery, let's find a compromise and reduce it 50 percent or reduce it 40 percent."
"We don't have a leader who is able to grasp it and say what is really needed," he added.
What he doesn't get is that in the US, no President has the ability to refuse to compromise. Here, just as Gore, Kerry or Obama, would not think to tell him to make changes to his analyses, they really have more expertise on developing public policy. The fact is that if someone like Kerry says that a carbon tax could not pass the Senate, I believe that he can count the votes.
