If covid proved anything than that the assumption that everybody has to lie for something like this is bs.

"All scientists and doctors^TM" changed their opinion on so many aspects so frequently that it just shows what that's worth. 

That being said, climate change is real. But always remember that the "expert" you listened to most likely just read an article of another expert and didn't actually bother to prove and check the stuff because of trust.

Climate change has been pretty lockstep since like the 60s? 

Even BP? did an independent study and confirmed this I believe but buried the results for a long time.
