The impacts of climate change are here. The Trump administration's actions will make them worse.

The West Is Losing Snowpack

Millions of people in the American West depend on snowpack, or the amount of snow that accumulates, for their drinking water, irrigation, electricity production, and tourism industries. There is extensive evidence that snowpack and snow extent in “the western USA have declined as temperatures have increased” due to climate change (Hicke et al. 2022). Of the surveyed sites, April snowpack declined at 81% of them, and the snowpack season became shorter at 80% of them between 1955-2023. The declining snowpack has increased and exacerbated water stress in the American West.

Warmer temperatures means that there will be less snow overall, but when temperatures stay below freezing, the extra moisture in the warmer air can make snowstorms heavier, like in the high mountains of the Sierra Nevadas in California (Scalzitti et al. 2016).

Weather and Climate Disasters Are Getting More Costly

Billion-dollar disasters include weather and climate events—flooding, wildfires, severe weather, droughts and heat waves, tropical cyclones, winter storms, and tornados—in the U.S. in inflation-adjusted dollars, although it may underestimate the average economic losses from events and cannot completely measure the costs of natural disasters due to the lack of data.

Over half of all global damages from extreme weather in the last 20 years are attributable to climate change, according to a Nature Communications paper. Additional factors such as increased population and expanded development are also contributors to the rise in billion-dollar disasters. Whether through more intense hurricanes and extreme precipitation, increased acreage of forest fires, or worsening and prolonged droughts, more Americans than ever are susceptible to the impacts of costly disasters.

Home Insurance Premiums Are Increasing

As the Earth heats up, sea levels are rising and storms, floods, and wildfires are getting worse in many places. That's putting homes, businesses, and entire communities at risk, contributing to higher premiums and making it harder to find insurance coverage.

Worsening extreme weather is among the factors driving up costs, alongside increasing building costs and construction in riskier, more disaster-prone areas

While prices are increasing all over, premium increases are hitting hot spots of climate risk like Florida and Louisiana particularly hard. Insurance companies are pulling back from high-risk areas, like wildfire-prone areas in California, or limiting coverage options. Higher premiums and worse coverage options have led to a growing insurance protection gap, especially among low-income homeowners, leaving more people burdened with greater costs of rebuilding after disasters.

Climate Pollution Will Increase

Rolling back the Endangerment Finding and vehicle climate pollution protections will lead to dirtier, less efficient cars and trucks on our roads. Transportation is the largest sector of climate pollution in the U.S., and these actions, through 2055, will result in up to 18 billion metric tons of additional climate pollution, approximately three times the total U.S. in 2025.

This map shows the increase in climate pollution projected to be emitted by each state, but the impacts of that pollution will be felt across the nation and globally. The many other actions the Trump Administration is taking to increase climate pollution and make the air dirtier, such as clean electricity and repealing standards on power plants, are not included in these projections.

We Will Spend More on Gas

Removing climate pollution standards for vehicles will mean dirtier, less fuel-efficient vehicles on the road that cost more to fuel. Between now and 2055, Americans will pay up to $1.4 trillion more for fuel. Higher demand will also drive up the cost of a gallon of gasoline, making it more expensive for Americans to get where they need to go.

Health Costs Will Rise

Repealing vehicle climate pollution protections also worsens air quality by increasing the soot and smog from vehicles and from the production of gasoline and diesel. This added pollution will increase health harms in the U.S. by up to $500 billion between now and 2055, including leading to up to 58,000 premature deaths. This air pollution causes premature death, asthma attacks, and hospital and emergency room visits that increase health costs and make Americans sicker.
