Climate change in Nevada

Climate change is affecting locations like Nevada in a variety of ways. In fall, these impacts include potentially hazardous atmospheric rivers, increased cooling demand, and changes to fall foliage.

Explore these pages to learn how people in Nevada are at risk in a warming world.

Since 1970, average annual temperatures in Nevada have gotten 3°F warmer, reflecting an overall warming trend.

Warming puts people and ecosystems at risk from more frequent and intense extreme weather.
Overall, the contiguous U.S. is about 2.8°F warmer today than in 1970, based on average temperatures.

Since 1970, Nevada's annual precipitation has decreased by 1.3 inches.

Climate change is supercharging the water cycle and bringing heavier precipitation extremes across the U.S.
For every 1°F of warming, the air can hold 4% more moisture, increasing the chances of heavier downpours that contribute to flash flooding hazards.

Nevada's climate threats in include:

Since 1970, average fall temperatures in Nevada have gotten 3.3°F warmer, reflecting an overall warming trend.

Fall warming means that risky heat, fire weather, and allergies linger later into the year.

About 100% of Nevada is currently in drought or abnormally dry.

Rising temperatures are worsening the risk of drought in parts of the U.S.
Droughts can lead to crop failure or pasture losses, impact water supplies, affect public health, degrade ecosystems, and increase the amount of fuel for wildfires by drying grasses and forests.
The map shows the percentage of land area that is abnormally dry (category D0) or in drought (categories D1-4). This is according to the U.S. Drought Monitor's drought classification scale.

Explore some ways climate change is affecting Nevada in fall

Warmer and wetter atmospheric rivers

Warming boosts moisture, making storms wetter, stronger, and costlier.

Key concepts:

Atmospheric rivers move huge amounts of moisture from tropics to poles.
When they hit land, they unleash intense rain and snow across U.S. regions.
In the West, they provide vital water and drought relief.
Back-to-back storms can trigger floods, landslides, avalanches, and levee breaks.
Warming boosts their moisture, making storms wetter, stronger, and costlier.

Higher cooling demand for schools

Hotter summers and longer warm seasons make cooling schools a growing challenge.

Key concepts:

Hotter summers and longer warm seasons make cooling schools a growing challenge.
Cooling is essential for student and staff health and safety.
Since 1970, cooling demand during back-to-school season rose in 95% of U.S. locations analyzed.
Rising demand means schools face costly upgrades to keep classrooms safe and comfortable.

Impacts to fall color

Conditions that trigger fall color are shifting with climate change.

Key concepts:

Foliage depends on temperature, day length, and rainfall — as well as other conditions including extreme weather events.
Cool fall nights can boost color, but they have warmed 2.7°F (1970–2023) in 212 U.S. locations.
Warmer falls can delay or shorten peak foliage.

More fire weather

Wildfire seasons are lengthening and intensifying.

Key concepts:

Climate Central analyzed U.S. fire weather (hot, dry, windy conditions) from 1973–2024.
Wildfire seasons are lengthening and intensifying, especially in the West.
Fire weather is rising most in spring nationwide

Impacts to food prices

Extreme events fueled by climate change can damage crops, reduce yields, and disrupt supply chains.

Key concepts:

Food and climate change are closely linked. Food systems account for about one-quarter of all heat-trapping pollution.
Meanwhile, extreme events fueled by climate change can damage crops, reduce yields, and disrupt supply chains — all of which can drive food prices higher.
The availability, quality, and affordability of food reflect a complex set of climatic and socioeconomic factors. Emerging research is providing insight into the role of climate change.
