Deadly Heat Waves Could Threaten 3 in 4 People By 2100

Even with aggressive reductions in carbon emissions, extreme heat is going to get worse, a new study has found.

WASHINGTON — If humans fail to drastically cut carbon emissions, 3 in 4 people on the planet could be exposed to deadly heat waves by the end of the century, a new study has found. 

And even if countries take action to reverse climate change with aggressive emissions reductions, up to 48 percent of the global population will be plagued by at least 20 days of lethal heat per year by 2100. 

And the problem isn’t just for the future. The threat is already here, with roughly 30 percent of the human population exposed to deadly conditions each year.
