Checkmate is a position in Chess, in which a player's king is in a line of attack by an opponent's piece and cannot escape check.
The new study focused on 14 measures with the greatest climate benefit. All 14 would curb the release of either black carbon or methane, pollutants that exacerbate climate change and damage human or plant health either directly or by leading to ozone formation.
Although scientists consider an abrupt climate change unlikely in the next 100 years, their understanding of the phenomena is still a work-in-progress, and such a change could be triggered instantly by natural processes or by human-caused global warming with little warning.
