I continue to be amazed at how the AGW hypothesis has become part of the conventional wisdom. People who have not a clue about science or the climate accept the concept, and refuse to even discuss the issue. Of course, they refuse to discuss it because they have no understanding of the issue. But, why do they believe it? They have some mindset that man is destroying the earth and making it worse for people. They believe that despite all of the contrary evidence. There seems to be so sort of suicide impulse. Consider these comments by the head of Caterpillar, for example. There is not much evidence that CO2 is adversely affecting the climate of earth, and much evidence that the general circulation models used as the foundation of support for the AGW hypothesis have failed to accurately predict the current climate. People need some instruction on the scientific method.
