Back in the early 1970s power plant pollution and auto exhaust were blamed for blocking the sun and causing THE COMING ICE AGE!
So the US cleaned up. Now we blame CO2 pollution for Glo-Bull Warming.
Maybe all those dirty power plants being built in China will save the world from “heating up”.

Changing the weather intentionally or otherwise weather modification..(Earth cooling vs Greenhouse effect)
“Do you suppose we can learn enough, soon enough, to pull off a balancing act with the CO2 blanket saving us from another ice age?”
“THE COMING ICE AGE!”
Don’t forget acid rain!
If you read geology you find out the earth’s climate has been all over the place i.e. river banks in the Sahara Desert.
Dr. Robert Forward (deceased) of Hughes Aerospace proposed sunlight levitated structures to hover over the Earth. These Static Satellites (Statites) are not in true orbit about the planet, but as solar sail propulsion devices, have the ability to station keep with the planet’s gravity providing an anchor.
They could provide extra insolation to counter a falling global temperature scenario. An early proposal called for these perpetual stations to hover over the Polar regions.
Also refer to Vladimir Syromyatnikov‘s work with illuminating areas upon the Earth with solar reflective light-sail devices.
