From hotter days to smokier skies and rising energy bills, climate change affects communities across the country. But the amount of warming varies by location.

A new analysis finds that all 435 U.S. congressional districts have warmed since 1970 — by 2.8°F on average. Human-caused climate change accounts for 91% of that warming.

Wondering where it has warmed the most? The fastest-warming districts are in the Southwest. Arizona’s 6th Congressional District has warmed by 5.1°F since 1970, nearly twice the national average.

WATCH: A sea star with 24 arms could help save California’s kelp forests.

Once abundant along the Pacific Coast, sunflower sea stars were devastated by a deadly disease beginning in 2013. Now, scientists in Monterey are working to bring them back.

Why does it matter? These voracious predators feast on purple sea urchins, which can decimate kelp forests when sea stars disappear. Healthy kelp forests absorb carbon dioxide as they grow, making their recovery important for the ocean and the climate.

Can these sea stars help turn the tide?

21 billion-dollar disasters. More than $50 billion in costs. No billion-dollar disaster category left unchecked.

For the first time on record, the U.S. has experienced impacts from all categories of billion-dollar disasters in a single year. Those 21 events include severe storms, tornado outbreaks, winter storms, flooding, agricultural freeze, hurricanes, wildfire, hail and drought.

And the year isn't over yet.

A powerful El Niño is developing in the tropical Pacific and is expected to influence global temperature and precipitation patterns through 2027. But how is that different from human-caused warming?

Both El Niño and human-caused climate change warm the planet in different ways. Human-caused climate change warms the entire planet over the long-term, while warming from El Niño is temporary and affects specific regions.

🍂 October is here — and fall is underway. What does the latest climate data tell us about the season ahead?

Join for our next Monthly Climate Brief on October 14 at 12 PM ET, featuring agricultural climatologist Pam Knox, for a look at the global climate rankings, the latest El Niño forecast, and how climate change is impacting U.S. agriculture.

🌊Last month’s nor’easter brought damaging coastal flooding along the East Coast — and higher seas driven by climate change made the impacts worse.

The storm produced strong winds, large waves, and repeated coastal flooding, with impacts prolonged as it stalled near New Jersey and Long Island.

As sea levels rise due to climate change, storm-driven increases in water levels are more likely to cause deeper and more extensive flooding.

☕ There’s more than caffeine brewing behind your morning coffee.

Climate change added more coffee-harming heat to the world’s major coffee-growing regions during 2021–2025, potentially affecting the quality and quantity of recent harvests.

The five largest producers, responsible for 75% of the world’s supply, experienced an average of 57 extra days of coffee-harming heat each year.

Achoo! Fall is finally here, and unfortunately, allergy season is sticking around.

Since 1970, fall warming has extended ragweed’s freeze-free growing season in 88% of 202 U.S. cities analyzed — by 11 days on average.

For the 50 million Americans with ragweed allergies, more time for ragweed to grow and release pollen can mean more time dealing with symptoms.

🌎 More than 1.5 billion people experienced at least 30 days of risky heat added by climate change this summer.

Climate Central’s latest analysis found that every day from June – August this year, more than one-quarter of the world’s population experienced a strong influence of human-caused climate change on daily temperatures.
