📈 It's official from NOAA. 2025 was the fourth-hottest year on record (since 1895) for the contiguous U.S. 🔥 Average temperatures for the contiguous U.S. in 2025 were 2.6°F (1.4°C) warmer than the 20th century (1901-2000) average. 🧵 Let's dig in a little deeper.
Bar graph showing US temperatures by year. Blue bars going down are temperatures below 20th century average and are present in beginning of graph 1895-1970s. Orange bars most recently indicate above-average temperatures. Temperatures are rising because of climate change.

A legacy of 2025’s Atlantic hurricane season is how fast storms intensified over unusually hot oceans. 5 hurricanes. 4 saw Extreme Rapid Intensification (58+ mph in 24 hrs). Ocean heat encountered made more likely by climate change: • Melissa: 500–900x • Humberto: up to 90x • Erin: up to 100x
Three side-by-side maps show the tracks of Hurricanes Melissa (left), Humberto (center), and Erin (right) during the 2025 Atlantic season, overlaid on Climate Central’s Climate Shift Index for ocean temperatures. Each map uses a red-to-yellow scale indicating how much more likely the observed ocean heat was due to climate change, ranging from near zero to over 800 times more likely.
