According to NOAA’s Arctic Report Card, the Arctic tundra region has become a source of carbon dioxide and methane to the atmosphere, driven by a combination of microbial activity in thawing permafrost and emissions from wildfires, which are becoming more frequent. In 2024, permafrost temperatures ranked highest on record at nearly half of Alaska’s long-term monitoring stations. Meanwhile, 2024 ranked as the second-highest year for wildfire emissions north of the Arctic Circle.

Hurricane Milton, the ninth hurricane of the 2024 Atlantic hurricane season, rapidly intensified into a Category 5 storm in the Gulf of Mexico on Monday, October 7, 2024. The storm exploded in strength and intensity at near record pace becoming one of the most intense hurricanes on record in the Atlantic basin. This explosive strengthening was fueled in part by record to near-record warmth across the Gulf of Mexico.

Sea surface temperatures have been record warm across the North Atlantic Ocean since March 2023. Temperatures have been so extreme that much of the North Atlantic has been experiencing a marine heatwave. This particular event has already brought devastating heat stress to nearly all of the Atlantic’s tropical reef areas and contributed to a very active 2023 Atlantic hurricane season.

Last month NOAA confirmed that the world’s fourth global coral bleaching event on record was underway. A global coral bleaching event means significant coral bleaching has been confirmed in all the ocean regions where warm-water corals live: the Pacific, Atlantic, and Indian Oceans in both the Northern and Southern Hemispheres. Since the beginning of 2023 and through mid-May 2024, mass coral bleaching has been confirmed in at least 62 countries and territories worldwide.
