Climate Change Boosts 2024 Atlantic Hurricanes' Wind Speeds by Up to 28 mph, Study Reveals
November 20, 2024MIT hurricane expert Kerry Emanuel noted that the study's findings align with his long-held predictions about climate change's intensifying effects on storms, which include faster intensification and slower movement, leading to heavier rainfall.
A recent study released by Climate Central on November 20, 2024, highlights that climate change has significantly increased the maximum wind speeds of all 11 Atlantic hurricanes formed in 2024, with intensifications ranging from 9 to 28 miles per hour due to warmer ocean temperatures.
Lead author Daniel Gilford noted that the behavior of hurricanes in the Atlantic has changed dramatically, with more storms intensifying rapidly and a greater proportion evolving into major hurricanes.
The findings underscore the urgent need for adaptation and preparedness as the severity of hurricane seasons increases, emphasizing the human impact on climate change.
Experts agree that as global temperatures rise, the likelihood of more powerful and destructive hurricanes will continue to increase.
The study's concept of potential intensity illustrates the maximum strength a storm can achieve based on environmental conditions, which is crucial for understanding the observed increases in storm strength.
Dr. Friederike Otto from World Weather Attribution pointed out that stronger storms create significant challenges for communities lacking resources to respond effectively, often resulting in tragic outcomes.
The research utilized computer simulations to compare current ocean temperatures influenced by greenhouse gases with a hypothetical world without human-caused warming, isolating the effects of climate change on hurricanes.
Gilford emphasized the correlation between storm intensity and the scale of catastrophic damage, highlighting that emissions of CO2 and other greenhouse gases have influenced global sea surface temperatures.
According to the National Oceanic and Atmospheric Administration, over the past 50 years, oceans have absorbed more than 90% of the excess energy trapped by greenhouse gases, contributing to the increased intensity of storms.
The study received significant funding from the Bezos Earth Fund and The Schmidt Family Foundation, reflecting the growing concern over climate change's impact on extreme weather events.
