Our final updates have been posted to the Climate.gov website, and this will be our final post to our social media channels.

Long-term trends in first leaf and first bloom dates across the U.S. are responding to long-term changes in temperatures. However, the trend across the Southeast may be surprising to some. Find out why: climate.gov/news-features/…

Extreme heat is worsening around the world and the stakes for heat safety are higher now than ever. Heat-related incidents at outdoor events are forcing the private and public sectors to confront the growing challenge of heat governance. Learn more: climate.gov/news-features/…

June 21 is Show Your Stripes Day—a time to spark conversation about how our world is warming. This video shows how @NOAA temperature data for the U.S. is turned into the iconic stripes visualizations you may see shared today and tomorrow. @NOAANCEI @ed_hawkins

Forecasting rain is more important than ever, but skill hasn't improved since the 1990s. @NOAA 's Climate Program Office is working with partners to boost accuracy and help communities prepare for extreme weather. Learn more: climate.gov/news-features/…

ENSO-neutral conditions are expected to continue through summer. While the odds of La Niña increase through the fall, the odds of neutral conditions continuing slightly outweigh those of La Niña. Find out what ENSO-neutral means for seasonal prediction? climate.gov/news-features/…

🍃These maps compare this year's leaf-out dates to the first bloom dates. Several areas were in sync. What was extremely rare was the combination of early leaves but late blooms. 💮 If you find an example let us know in the comments! Read more: climate.gov/news-features/…

JUST IN: Atmospheric carbon dioxide (CO2) concentrations have peaked for the year at 430.5 ppm.📈 This is 3.6 ppm higher than last year and the second largest May-May increase in the 67-year Mauna Loa record. In 2023, the CO2 peaked at 424 ppm. 🔗: gml.noaa.gov/ccgg/trends/
