“This is going to be a long-duration event,” said UCLA climate scientist Daniel Swain. “And that’s sort of characteristic of heat domes — that’s partly because they can sort of be self-persisting, self-reinforcing. Once they develop and become particularly extreme, they kind of become hard to dislodge.”
