Climate science is, of course, a huge topic, but here I would like to focus on one matter: the very notion of the globally and annually averaged temperature anomaly (that is, departure from a reference value or long-term average) as a unique metric of climate.
He posits some points on this single topic, then goe off on a comparison of "Eugenics" in the Soviet Union during the reign of Stalin and it's advocate Lysenko.
Big deal, his own summation does not refute global warming issues, he just wants people to consider it more "objectively." As if those scientists who form the consensus don't?
Now again, I am no expert and I do want to know the truth. I don't like scare tactics whoever uses them. But I am also aware of major climate changes between my childhood and now. There is no argument that the polar caps are melting, the sea is rising, and our weather is Effed up! Based on that I'd side with the consensus and not the "nothing to see here folks" advocates.
The Northern ice Cap is not as expansive today as it was in the 70's. It is greater right now than in the last 6 years.
The Sea level is rising. It does not seem to be rising as fast as some like to claim that it is and mysteriously, even though the warming out of the Little Ice Age has been ongoing for about 400 years, the party line is that the sea level only started to rise after 1900. Does this make sense to you?
The weather has always been contrary to the goals and dreams of men. History is replete with stories of drought and famine, flood and fire. In what ways do you suppose things have changed today vs. the biblical stories of pain and destruction? This would indicate problems long before the first steam engine got fired up by coal. It is quite likely that Napoleon lost the Battle of Waterloo because it rained.
What is your evidence that the ongoing problems with the changing weather which are very similar to all of the past changes are now caused by something different than what has caused them throughout history?
Presenting things that have happened with regularity absent the cited cause of today as evidence that the same things happening today prove a new and unique cause is responsible does not stand up to logic.
To prove the connection, you need something more compelling than, "Trust me."
