Topic: Marine heat waves

February 18, 2024: Waves roll toward the shore on Lake Michigan in St. Joseph, Michigan.The Great Lakes shorelines are historically ice covered this time of year. Persistent warmth resulted in a steady decrease in ice coverage across the Great Lakes this winter, which reached a historical low of 2.7% on February 11.

On September 27, 2023, the VIIRS instrument onboard NOAA’s JPSS satellites captured this GeoColor imagery of Canadian wildfire smoke being pulled across the Atlantic Ocean by two areas of low pressure—one swirling system can be seen in the left of this image and the other, deemed Storm Agnes by the UK Met Office, is on the right near Ireland and the United Kingdom. GeoColor imagery provides a close approximation to what you would see with your naked eye from outer space.
