Fracking natural gas is not going to help - a large amount leaks at the fracking site, and in the area around it. Also, pipelines leak a lot. Methane is a far stronger greenhouse gas than carbon dioxide. It is barely better than coal, and may even be worse, because of all the possible leaks.
And in a short period of time, methane breaks down, and we get more carbon dioxide. The climate doesn't "care" who or where greenhouse gases are produced. Most of what has already been emitted - came from the USA.
If we want to avoid 2C warming, then we have to leave 4/5ths of the known fossil fuel reserves - IN THE GROUND.
