The leftist's persistent and indefensible denial of the lack of science of climate change, is the real problem. That is, the science is far from settled!
The leftists melt away when asked to show the science supporting their claims of climate change being caused by mankind. The well funded leftists are guilty of lysenkoism.
The entire country and world would benefit by a red team/blue team assessment of the role of mankind in climate change. Real science will show that the dominate factor in climate change is the Sun.
Lysenkoism is used metaphorically to describe the manipulation or distortion of the scientific process as a way to reach a predetermined conclusion as dictated by an ideological bias, often related to social or political objectives. It is a reductive view of human nature and action, based on selective evidence, unexamined assumptions, and jargon modeled on real science.
