From deadly wildfires to floods, the US is reeling from several natural disasters in quick succession — and more are likely on the way.

Torrential rains from the remnants of Hurricane Hilary are inundating parts of California. Two tropical storms, one post-tropical cyclone and two potential storms are lined up in the Atlantic Ocean. Almost 100 wildfires are burning across 15 states as officials in Hawaii investigate the deadliest US blaze in more than a century. And record heat will test Midwest power grids this week.

All of this, all at once, is a lot — and it’s not just bad luck. Climate change has triggered heat waves around the world, leading to ideal fire conditions in forests across the Northwest and Canada. It’s also boosting Atlantic water temperatures, which can intensify storms as the peak of hurricane season approaches. And unusually warm Pacific Ocean waters fueled Hilary, which in turn will contribute to scorching heat in the Midwest.
