Record-breaking ocean temperatures, fueled by human-induced climate change, have significantly strengthened Atlantic hurricanes in recent years, making them more potent and dangerous. According to a new analysis by the nonprofit climate research group Climate Central, every hurricane during the 2024 Atlantic hurricane season was made more robust than it otherwise would have been without the effects of human-caused carbon pollution.
Ocean waters, heated to 2.5°F warmer due to climate change, amplified hurricane wind speeds by 9 to 28 mph across the 11 hurricanes recorded this season. This acceleration of wind speeds pushed many storms into higher categories on the Saffir-Simpson hurricane wind scale, increasing their destructive potential. “Every hurricane in 2024 was stronger than it would have been 100 years ago,” said Daniel Gilford, a climate scientist at Climate Central and the report’s lead author. “Through record-breaking ocean warming, human carbon pollution is worsening hurricane catastrophes in our communities.”
The findings are part of a broader analysis revealing that 84% of Atlantic hurricanes between 2019 and 2023 were more intense due to climate change. On average, these storms had wind speeds cranked up by 18 mph, with 30 storms escalating by at least one category due to warmer oceans.
The role of warming oceans is undeniable. According to the National Oceanic and Atmospheric Administration (NOAA), over 90% of global warming has occurred in the oceans over recent decades. The Atlantic, in particular, saw water temperatures near record-breaking levels throughout the 2024 hurricane season, fueling hurricanes to strengthen and rapidly intensify more frequently. Rapid intensification, defined as an increase in wind speeds of at least 35 mph within 24 hours, occurred in nine of this season’s 11 hurricanes.
Category 5 Hurricane Milton, one of the most devastating storms of the season, exemplifies this trend. Milton rapidly intensified by 95 mph in just 24 hours, according to the National Hurricane Center, setting a record as the fastest intensifying storm in the Gulf of Mexico. These alarming statistics underscore how human carbon pollution directly influences hurricanes’ intensity and frequency.
The analyses highlight the urgent need to address human impacts on climate change, which not only exacerbates storm intensities but also endangers lives and communities along hurricane-prone coasts. As the oceans continue warming, the question looms: how much stronger will storms become, and how can we mitigate the damage? Read More
