Those people still supporting AGW (anthropogenic global warming) are dependent on funding to support their current positions. That funding is in turn dependent in the continuation of faith that AGW (anthropogenic global warming) is correct. After all, when Galileo proved that the Earth Orbited the Sun, funding for continued research into epicycles vanished abruptly, along with tenures and the value of every degree issued in the field of Epicycles.
The same applies here. With precious rare exception, every academic whose degree and funding is based on AGW (anthropogenic global warming) is looking at a stark unemployment picture. In their minds, they are not fighting for scientific truth; they are fighting for their livelihood, and the proof is very simple. If their primary concern was really the long term welfare of planet Earth, one would think the Global Warming Cult would be delighted to find out there really is no danger after all. But, as is clearly evident, the goal is to support the orthodoxy even against the revelation that their core scientific foundation is based on a fraud.
