A projected mean increase of 70% human mortality over

Results. Projected regional increases in heat-related premature
mortality by the 2050s ranged from 47% to 95%, with a mean 70%
increase compared with the 1990s. Acclimatization effects reduced
regional increases in summer heat-related premature mortality by about
25%. Local impacts varied considerably across the region, with urban
counties showing greater numbers of deaths and smaller percentage
increases than less-urbanized counties.

Conclusions. Although considerable uncertainty exists in climate
forecasts and future health vulnerability, the range of projections we
developed suggests that by midcentury, acclimatization may not
completely mitigate the effects of climate change in the New York City
metropolitan region, which would result in an overall net increase in
heat-related premature mortality.

Has the reduction in Cold related deaths as the climate warms been
projected ?
There are many many more deaths in cold winters than in hot summers in
the UK
