The CAGW Hypothesis is based on this set of assumptions/observations:
1) Evil Mankind has caused atmospheric CO2 levels to rise drastically in the 20th century (Keeling Curve)
2) Temperatures rose drastically in the 20th century (Global Warming)
3) The frequency of climate disasters has risen drastically in the 20th century.
4) None of these drastic conditions ever happened before.

Of course, there is no compelling proof (other than model simulations) that any these assumptions are historically unique or valid. [Even 1), which could be the result of outgassing from the oceans or other natural mechanisms.]

But that doesn’t stop the warmists from claiming:
1) caused 2) which in turn caused 3). => CAGW:”man-made CO2 has caused/will cause climate disasters”

But if you ask: “didn’t temperatures rise to these same levels (or higher) in the past when CO2 levels were lower?”

The answer must always be: “No! It has never been this hot before. ‘Hottest year ever’ etc. So that proves it must be the CO2 causing all these disasters. What else could it be!”

Well, for starters, it could be that temperatures, hotter than now, gave rise to these giant clams and allowed Vikings to do farming in Greenland, when CO2 levels were much lower.

Therefore the main argument of CAGW (historical “unprecedentedness”) would be demolished. But only if these findings show that today’s “global warming” was not unprecedented.

So you will see a lot of hand-waving, model and data “adjustments”, and moving of goal-posts by the warmist community in order to preserve this notion of “unprecedented”.
