China is still a relatively poor country, which means that abandoning coal as a its main source of power would not be a prudent decison to make in a nation where conditions are largely third-world. As for the U.S, blame a dominant Republican administration that has has been bribed by the powerful energy cartels into convincing the American public that the whole idea of global warming is just a hoax.
