Sentences with phrase «dangerously humid days»

If we choose not to reduce emissions of heat - trapping gases and instead continue to rely upon fossil fuels, the average American could expect to see about 17 dangerously humid days in a typical summer in 2050 and about 35 in 2090.

Moderate reductions in emissions of heat - trapping gases — sufficient to stop global emissions growth by 2040 and bring emissions down to half their current levels by the 2070s — can avoid those paralyzing extremes and limit the expected late - century experience of the average American to about 18 dangerously humid days a year.
