Well, it's a bit more comlex than that, but unfortunately the Politicians are wrong, as well and misinforming the public
... In other words...
Damn good question!!
GeoPhysicists claim that the average Earth temperature for the 19th C. was warmer than the 20 C. by 6 degrees.
I agree that pollution contributes to problems with the Environment, but I think there are much deeper things we have yet to learn - such as Standard Cyclical Earth Functionality -- Maybe we're headed for Our "Jungle" period, then that may be followed by another Ice Age.
We do NOT know enough right now -- and no matter what we do about Pollution - IT MAY NOT MATTER.
The only thing Hotter than normal, on this planet is Propaganda & Politics.
Get it, Got it, Good!!
Pertinent Question, Kingler :-) !! I just wish others would Get it.
