“The estimated cost of measures to limit Earth-warming greenhouse gas emissions can be more than offset by reductions in deaths and disease from air pollution, researchers said on Saturday.  It would cost $22.1 trillion to $41.6 trillion between 2020 and 2050 for the world to hold average global warming under two degrees Celsius (3.6 degrees Fahrenheit), a team projected in The Lancet Planetary Health journal.
For the lower, aspirational limit of 1.5 degree Celsius, the cost would be between $39.7 trillion and $56.1 trillion, they estimated.  But air pollution deaths could be reduced by 21-27% to about 100 million between 2020 and 2050 under the 2 degrees Celsius scenario, the team estimated, and by 28-32% to about 90 million at 1.5 degrees Celsius.”  The Hindu
