Four winters. Four of the lowest Antarctic sea ice peaks on record. 2026’s winter maximum ranked third-lowest. By early October, ice extent hit record lows for the time of year. What’s driving the losses? Scientists are investigating. buff.ly/s5NvZgm

El Niño strengthened in September. NOAA now gives it a 100% chance of becoming “very strong” by Sep–Nov. For coastal communities, that can mean more high-tide flooding. Our latest blog explains the forecast and how to check your local flood outlook. buff.ly/RhDQwOG #ElNino #ClimateScience #ENSO

In 2015, unusually heavy rain soaked Illinois pumpkin fields during a critical growing period, contributing to poor yields. A seasonal reminder that climate and weather can reach all the way to our porches—and our pies. buff.ly/uGqGgyd #ClimateScience #Pumpkins #Fall #Agriculture #FromTheArchive

After it rains, go outside and breathe in deeply. That wonderful earthy smell in the air? It’s called petrichor. And climate change could alter when and where it happens.

2026 has been a record hot year for the U.S. If it stays that way, 2026 could set a sobering new record.

October outlook: No part of the U.S. is favored to have a cooler-than-average month. Meanwhile, nearly 80% of the contiguous U.S. entered October abnormally dry or in drought. See NOAA’s temperature, precipitation & drought outlooks: buff.ly/i7Blwc7 #ClimateChange

Why is the Atlantic so quiet while the Pacific is so busy? As of Sept. 21: - Atlantic: 6 named storms, 0 hurricanes - NE Pacific: 17 named storms, 6 hurricanes El Niño explains why. Changes in the tropical Pacific can reshape hurricane activity. Learn more: buff.ly/BiTvfTn #ClimateWeekNYC

Arctic sea ice likely reached its 2026 minimum on Sept. 12, tying for the 10th lowest in the satellite record. The long-term decline is clear, even though the trend has flattened since 2007. Scientists are studying why—and what it means. More: www.climate.us/news-feature... #ClimateWeekNYC

Summer 2026 was the warmest on record for the contiguous U.S., according to NOAA, surpassing previous records set in 1936 and 2021. August also set a new temperature record, while drought expanded across much of the country. Visit Climate.us for more climate news, data, and trends.

Update on #NCA5: Thanks to the last-minute push by so many of you last week, more than 100 comments were submitted on the proposed amendment before the Sept. 9 deadline. Thank you for making your voices heard and supporting a transparent, rigorous scientific process.

It wasn’t just a hot summer. Summer 2026 was the warmest on record for the contiguous U.S., according to NOAA NCEI, and August was also the warmest August on record. Meanwhile, drought expanded to 59% of the country. Visit Climate.us for more climate news, data, and trends.

ICYMI: Want to see what El Niño looks like? Look at the clouds. More clouds and rain are developing over the warm central tropical Pacific, while the western Pacific is becoming clearer and drier. It’s a classic El Niño atmospheric pattern—and it strengthened in August. buff.ly/0UwAHRd

There’s a 100% chance of El Niño continuing through winter. Yes, 100%. And there’s now a 75% chance it could become the strongest El Niño on record by October–December. So what are scientists seeing? @ClimateUS has the pictures. buff.ly/i7y8Yxm

Sea Ice Today is back! For nearly two decades, scientists at the National Snow and Ice Data Center, or NSIDC, have helped people understand what is happening to sea ice in the Arctic and around Antarctica. Its monthly science analyses were paused last fall. buff.ly/e20zCU6

Gov't plan to revise key climate report lists no scientists as authors and offers no information on how the plan will be peer-reviewed. You don’t have to be a climate scientist to know this isn’t how science should be done. Use your voice! Comments due Sept. 9: buff.ly/irGbLiR #NCA5

September is here, but that doesn’t mean the fall weather is. Much of the U.S. is leaning warmer-than-average this month. Parts of the West could see wetter conditions, with some drought improvement possible. www.climate.us/news-feature... #Climate #Weather #September #Drought #ClimateScience #NOAA

We've corrected an error in last week's Lake Powell graphic (wrong axis scale + a timing mistake on seasonal peaks) and simplified the chart design. The core finding is unchanged: record-low lake levels. See the updated post at Climate.us: buff.ly/vMyell3 🌍️🧪 #LakePowell #MegaDrought #ClimateChange

Where does most excess heat from climate change go? The ocean. Nearly 90% of it over the past 50 years. This map shows 2025 ocean heat content vs. the 1993–2022 average. Orange = more stored heat, and that's most of the map. Read more BAMS State of the Climate highlights: buff.ly/Y18qfMf 🌍️ 🧪
