Mann’s Hockey Stick also fails to point out that we had the “Little Ice Age” from 1500-1800, when temperatures dropped substantially below normal.
Consequently, his chart of “modern times” starts at exactly the point where temperatures began to rise.
We have a similar flaw in our temperature satellite data.
From 1940-1980, we had below average cool weather.
The first weather satellites launched in 1979, exactly when temperatures began to rise.

Good point.
It’s important to note that during the Little Ice Age, sunspots hit a minimum (cooler sun) (~1650-1720, the Maunder Minimum) and those same sunspots began to increase about the same time as the industrial revolution and Current Warming Period.
So as you say, the climate kooks start their pretty little graphs right at the end of a natural cooling time period.
