Humans are increasing wildfire risks, but “bad environmental laws” aren’t the problem.

The 2018 wildfire year has been devastating. As of Monday, the National Interagency Fire Center reports that there are 60 uncontained large fires across the country.

These deadly infernos have killed several firefighters, forced hundreds of people to flee, and destroyed hundreds of homes and thousands of acres of wilderness.

The Carr Fire in Northern California is now the state’s fifth-largest fire on record after igniting more than 160,0000 acres and has already killed seven people. But it’s been bested in size by the Mendocino Complex fire, which, at 273,000 acres, is the second-largest in state history. The largest remains last year’s Thomas Fire.

Late last month, President Trump signed a federal emergency declaration for the state of California, allowing the federal government to assist with firefighting efforts.

So it’s not surprising that Trump would weigh in on the California blazes. But on Sunday night, he used them to bash environmental regulations:

There are a few things that are bewildering about this statement. First, human activity is definitely making these fires worse: People are building in vulnerable areas, they are igniting most of these fires, and humans are driving climate change, which makes fire conditions more severe.

But environmental laws about water that would be used to put the fires out?

Even wildfire scientists don’t really know what the president was referring to. California has been parched from drought for years, so there isn’t a “massive amount of readily available water,” and what little moisture is available is closely tracked.

“We do manage all of our rivers in California, and all the water is allocated many times over. So I’m not sure what he was recommending,” LeRoy Westerling, a professor at the University of California Merced studying wildfires, told the San Francisco Chronicle. “Even if we eliminated all habitat for riparian species and fish, and allowed saltwater intrusion into the delta and set up a sprinkler system over the state, that wouldn’t compensate for greater moisture loss from climate change.”

That means if California hoarded every raindrop instead of “diverting into the Pacific Ocean,” it still wouldn’t completely offset evaporation from rising average temperatures and years of drought.

This water also wouldn’t be all that useful for firefighters. Wildfires are a natural part of the ecosystem, so the goal is to allow these fires to burn without threatening lives and property, and spraying water isn’t the main method for containing them.

For wildland firefighters, the tools of the trade are Pulaskis, rakes, shovels, and flamethrowers that burn clearings ahead of towering infernos. Instead of fire engines, they use bulldozers. Since these firefighters aren’t usually using pump trucks and fire hoses, they aren’t limited by water. When they need to snuff out an area, they often do it by air.

These methods help firefighters clear a perimeter of potential fuel to control the spread of flames. But as Westerling added on Twitter, the president’s suggestion of “tree clear” only goes so far.

There were indeed regulations that prevented firefighting equipment from being used, but officials say water rules are not hampering firefighting efforts. In fact, the largest fires in California right now have plenty of water nearby. Scott McLean, a spokesperson for the California Department of Forestry and Fire Protection, pointed out that the Carr Fire burned around Shasta Lake while the Mendocino Complex Fire is near Clear Lake.

For a state like California that’s facing increasing heat and more frequent weather whiplash between extreme rain and drought, the real “bad environmental laws” worsening the situation are actually Trump’s attempts to roll back policies — like California’s Clean Air Act waiver — that would help mitigate climate change.
