📈 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.

We’ve always had floods – but as the world warms, they’re becoming more intense and more severe.
We’re all in harms way – but those who don’t have a safe place to live, or can’t take food and water for granted, are always most vulnerable.
