A greenhouse gas that can cause 12,000 times more warming per tonne than carbon dioxide is rising unexpectedly in the atmosphere, despite reports by its major producers, China and India, that they’ve mostly eliminated emissions of the gas. Atmospheric gas measurements at five stations around the world show that emissions of HFC-23 or trifluoromethane reached…
