Sorry, there is nothing we can do to stop global warming that would make a significant difference.
There are some that will say, "If everyone would just..."
But we know that "everyone" (or every country) will not work together for any cause. That is wishful thinking.
People will not give up burning fossil fuels because we very much like our cars, electricity, manufactured products, shipping, heating/cooling our homes etc.
Any national leader that tries to take those things away would soon be out of a job… or worse.
Eventually, national leaders with throw tons of money at the problem. The results will be negligible.
