She cited the 2.5C rise in temperatures during the Medieval Warm Period as having had almost entirely beneficial effects. She pointed out that the dangers of a world getting colder are far worse than those of a CO2-enriched world growing warmer. She recognised how distortions of the science had been used to mask an anti-capitalist, Left-wing political agenda which posed a serious threat to the progress and prosperity of mankind.

2.5 degree change in the Medieval Warm Period? How come I did not know?
Time for a fact check...

https://en.wikipedia.org/wiki/Medieval_Warm_Period

The Medieval Warm Period (MWP) also known as the Medieval Climate Optimum, or Medieval Climatic Anomaly was a time of warm climate in the North Atlantic region that may have been related to other warming events in other regions during that time, including China[1] and other areas,[2][3] lasting from c. 950 to c. 1250.[4] Other regions were colder, such as the tropical Pacific.

So it wasn't a global effect. That '2.5 degree change' wasn't even 0.25 degrees globally. It falls way short of the current situation.
It must be another distortion of science by a right-wing politician, which she happened to be.
