Because, you know, the prediction market in nice oceanfront properties beloved by the coastal elites hasn't collapsed, even tough their tongues say they believe.
I don't trust that website. I know for a fact that their #4 issue is a bust. I tracked down the 'consensus' paper that had 97% of a few dozen climate scientists say that humans are having an impact. I don't believe in CAGW because of the math, and I agree with those 97% scientists. The rest of the papers that reference the 97% consensus fail to qualify it that the consensus was about any impact at all however little. I think CO2 having a logarithmic warming effect should frankly be the end of the argument.
Some just choose to ignore them.
