Across the globe, this summer has been unusually, unseasonably, and scarily hot, with the United Nations announcing that we’ve entered the era of “global boiling.” Scientists say this extreme heat wave would be impossible if it weren’t for the warming caused by the burning of fossil fuels. And yet it’s hard to grapple with the damage caused by extreme heat. It’s the deadliest kind of climate disaster, and yet victims of heat often die out of sight of the public eye. FEMA doesn’t even respond to extreme heat waves in the way it does to other “major disasters.” Jake Bittle is a staff writer at Grist covering climate impact. In this conversation, Bittle speaks with Brooke about the invisibility of extreme heat, and the challenge it presents to news outlets, and the potential value of naming heat waves.
