While deaths and destruction are mounting and tens of thousands flee a devastating inferno in Los Angeles, the President-Elect has used the catastrophic wildfires to spread misinformation, offer false solutions, and disrespect the suffering of people and the hard work of first responders. Here, we provide the facts and avoid the fiction.
Fact 1: reservoirs are full
Due to a relatively wet winter in Northern California, almost every reservoir in Southern California is at or above its historical average. There is ample water available in reservoirs to fight fires. The challenge is getting the water from the reservoir to the fire fighters.
Fact 2: California’s water system is a patchwork
California, like most states, has thousands of water systems. Federal, state, municipal, regional, and private water systems co-exist. Some are connected to each other, some aren’t. What happens hundreds of miles away in one system does not necessarily have an impact on your local supply. In other words, decisions about federal water in one part of the state don’t automatically increase or decrease how much water your local utility has available.
Fact 3: City water systems are not designed to suppress massive wildfires
Cities build infrastructure to meet demands without being unnecessarily expensive. For example, water systems are designed for the capacity to deliver enough water to serve customers’ normal household water needs and to provide a limited amount of “fire flow,” or excess capacity for fire suppression. During the initial hours of the Palisades fire, the LA Department of Water and Power experienced unprecedented water demand — four times the normal water use for 15 hours straight. This incredibly high, sustained level of water demand outstripped the ability of the system to keep the water flowing. It was water use, not water supply, that led to a temporary shortage for fire flows.
Fact 4: Fire fighters often rely on air support to contain rapidly burning fires
The Palisades fire ignited during some of the worst Santa Ana winds, gusting at more than100 miles per hour at times. This made air support dangerous and unreliable during the critical first few days of the fire, placing a larger burden on the municipal water system.
Fact: Wildfires are worsening due to climate change
At a basic level, the connection between wildfires and water is intuitive: fires start more easily, burn more intensely, and spread faster when it’s dry and hot. That’s bad news, because climate change is increasing temperatures and the risk of drought in many regions. It’s particularly pronounced in the western United States, where heatwaves and megadroughts are priming us for wildfire. In fact, western landscapes are now roughly 50 percent drier due to climate change.
Fact: Fossil fuel companies are privatizing profit and socializing costs of climate change
Emissions from the products of fossil fuel companies and cement manufacturers have fundamentally reshaped the climate of western North America and left behind a scarred, charred landscape in which people, communities, and the ecosystems that enable their existence are suffering. To-date, taxpayers and victims have been footing the bill for worsening wildfires.
However, UCS’s new analysis quantifies the contribution of fossil fuel companies to fire conditions. Federal, state, and local governments have the power to hold fossil fuel companies accountable for the costs of climate change impacts. And they should.
