The Biden administration has opened a global climate summit including 40 world leaders.

Biden recently announced a pledge to cut at least in half the climate-wrecking coal and petroleum fumes that the U.S. pumps out. That's a commitment Biden hopes will spur China and other big polluters to speed up efforts of their own.
