If there's really global warming, there is a simple solution, proposed by Dr. Edward Teller.
All that is necessary is to reduce the amount of sunlight reaching the earth by about 1% or 2%. This can be done easily with artificial clouds.
These 'clouds' can be placed in orbit between the sun and the earth, will be invisible, and will block enough sunlight to
end the 'global warming'.
First you have to prove there is such a thing as global warming, and no one has done that yet.
Second you have to prove that global warming is a negative rather than a positive. Remember that the opposite of warming is cooling, and we're about due for another Ice Age.
The "unintended consequences" of cooling the earth to prevent warming may provide us with a disaster of global proportions if the ice starts to move this way.
They are already doing that. It's outlined in Weather as a Force Multiplier:Owning the Weather in 2025
