30 years ago was a bad day for science

This article is fairly accurate. It doesn’t point out the real reason that Hansen was wrong and that anthropogenic global warming (AGW) has essentially slowed down to almost stopped.

The real reason is that it is the physical and energy nature of the CO2 molecule that it simply has no more radiation to absorb. CO2 can only absorb a very narrow band of radiation and that radiation is approximately 95-98% absorbed already. You could triple the CO2 in the atmosphere and all you would do is decrease that narrow band closer and closer to 0% (it is impossible to get 100%). That simply means a 2-4% increase in absorption in about 1/10th of the wavelengths that are long enough to be called “heat”.
