Yup. Learned enough to KNOW just how many eons existed before combustible engines.
AND, how many we have now, ALL spewing emissions. Billions of cars, trucks, etc.
Not to mention factories, coal burning electrical facilities, etc.
Let's see, eons with no exhaust fumes, just campfire smoke from not that many humans and natural wildfires.
Then the recent 150 years of ever increasing exhaust emissions and Voila.......... the climate is getting weird.
Too hot in places, oceans rising (been to Venice lately?) continents on fire........
I don't care if you've been to school Dougie..........can't you THINK?
It's a rather simple common sense equation.
Exhaust emissions results in atmospheric "issues".
What's so difficult to get?
Unless you're an ostrich............or Don't wanna KNOW the truth because YOU CAN'T HANDLE THE TRUTH!
In other words a moral coward.
