While one-at-a-time disasters fueled by a rapidly warming planet have become commonplace in recent years—with the ongoing and deadly wildfires in California just one example—new research shows that by century’s end the frightening new normal could be cities and states facing multiple extreme climate events all at once.

Researchers at the University of Hawaii found that without keeping the warming of the planet below two degrees Celsius above pre-industrial levels, major cities like New York, Sydney, and Rio de Janeiro could soon face up to five catastrophic weather events in a single year—including wildfires, hurricanes, storm surges, and droughts.

The phenomenon has already taken place, the report notes, with Florida experiencing more than 100 wildfires, drought, and the severely destructive Hurricane Michael in the past year—but with most news reports and climate researchers focusing on one disastrous weather event at a time, the current reality has been obscured.

“A focus on one or few hazards may mask the impacts of other hazards, resulting in incomplete assessments of the consequences of climate change on humanity,” lead author Camilo Mora told the Agence France Presse.

The report only bolsters the argument of those forced to issue urgent action demands in the wake of whatever climate-related disaster has most recently struck. In the U.S. right now, that means the unprecedented wildfires that have ravaged California in recent weeks.

“The costs of inaction greatly outweigh the costs of taking action on climate change,” Michael Mann, a climatologist at Penn State University, told the AFP. “We can still reduce future damage and suffering if we act quickly and dramatically to reduce carbon emissions.”

At least 80 people have been killed in the fires, with nearly 1,000 unaccounted for as of Tueasday morning, according to NBC.

“An untold number of people lost their lives due to the Camp Fire wildfire in California, many are missing and communities have been destroyed. Last week, the air quality in Sacramento and the San Francisco Bay were the worst on the planet,” said Abigail Dillen, president of Earthjustice, in a statement.
