Here's a snow map for the history books.

The Jan. 21-22, 2025 Gulf Coast blizzard produced 8 inches of snow or more in six states: Louisiana, Mississippi, Alabama, Florida, Georgia, and North Carolina.

There was a storm maximum of around a foot near New Orleans.

A State Climate Extremes Committee said “Hail yes!” to a new state hail diameter record set near Kirk, CO on Aug 8, 2023. Besides its impressive 5.25” in diameter, the stone raised questions too. @NWS @NWSGoodland @IBHS_org @ColoradoClimate https://t.co/WhIkMAST6D

More than 90 percent of the warming that has happened on Earth over the past 50 years has occurred in the ocean. Not all of that heating is detectable yet at the surface: https://t.co/kXjgiTmKlx

⚠️ The warmest July on record for the globe: https://t.co/GakXvhshTa #StateOfClimate

[NOAA Satellites @NOAASatellites]

Many of Florida's #CoralReefs have been hit with severe bleaching and significant mortality due to extremely warm ocean temperatures, and @NOAA's @CoralReefWatch has been tracking the threat.

In this Bleaching Alert animation, you can see how the threat has grown over the last two weeks.
