You just hit on an extremely important point: When do changes in the weather become climate change?
Certainly, the weather everywhere varies to some degree - for example, the temperatures tonight or this week / month / year / decade / century in any part of the world won’t be exactly what they were last night or last / month / year / decade / century, although the variation will be different.
But, what I have noticed is that the climatists are starting to reduce the period over which they say climate “change” is occurring.
If I can define climate change from any base period I choose, I can definitively state that’s it’s getting cooler or warmer, whichever is the most politically correct. But, then, that is not science, it’s religion!
Excellent points.
