At the global level for PM2.5, annual premature deaths due to climate change were projected to be 55,600  and 215,000  in 2030 and 2100, respectively, countering by 16% the projected decline in PM2.5-related mortality between 2000 and 2100 without climate change . Similarly for ozone, the number of annual premature ozone-related deaths due to climate change was projected to be 3,340 in 2030 and 43,600 in 2050, with climate change accounting for 1.2%  of the annual premature deaths in 2030  . These global level projections average over considerable geographical variations . Projections of the climate change effect on ozone mortality in 2100 were greatest for East Asia , India  and North America . For PM2.5, mortality was projected to increase across all regions except Africa  by 2100, with estimated increases greatest for India , the Middle East , East Asia  and the Former Soviet Union . Overall, higher ozone-related health burdens were projected to occur in highly populated regions, and greater PM2.5 health burdens were projected in high PM emission regions .
