Are human beings causing climate change? See here. I’m not a scientist, and I don’t even play one on TV, so I have to rely on scientists for information about climate change. The problem—besides the fact that there is no scientific consensus on the matter—is that scientists can no longer be trusted to stick to science. They want to make policy. Don’t they realize that by joining the political fray, they undermine their credibility and authority? Either (1) they think Keith’s Law is false or (2) they’d rather be partisan than authoritative.
