You better believe it. I was a kid in the 1970s and I remember the stories, propaganda and even cartoons pointing out that mankind was polluting the air and that was blocking the sun cooling the earth. I think temperatures were level for a week in 1979 when climate wasn't our fault.
Reduction of sulfur dioxide emissions and smoke suppression are the most likely man made causes of global warming. Therefore those responsible for enacting the Clean Air Act and similar legislation are to blame for any global warming.
There’s an interesting line in the book “Lucifer’s Hammer”. The astronauts are circling the earth, discussing how we’re probably entering a new ice age versus global warming.
One astronaut says the pollution and heat pollution are probably the only reason we aren’t in an ice age then, when the other says “But we’re running out of oil!”
