plant trees and use solar electricity. ride a bicycle instead of a petrol bike.
we can't stop global warming. perhaps we can reduce and mitigate its effects to a rate slow enough to adapt to and avoid major tipping points. simply put, we need to dramatically reduce the amount of greenhouse gases we produce.
fire the leftist professors who claim it exists.
unsure, needs more research. however, less greenhouse gas production is a good starting point.
wait it out
i think electric cars would be great, but because of money (oil) or other people's stupidity, it will never stop :(
