A recent study by World Weather Attribution has revealed that human-caused climate change increased Hurricane Helene's rainfall by approximately 10% and intensified its winds by around 11%. The research highlights that the warming climate made high sea temperatures, which fueled Helene, 200 to 500 times more likely.
The study found that Helene's wind speeds were boosted by about 13 mph, with ocean temperatures in the Gulf of Mexico averaging 3.6 degrees Fahrenheit above normal. The findings indicate that the extreme conditions of Helene, which resulted in record storm surges and catastrophic winds, were exacerbated by climate change.
Scientists warn that similar intensification can be expected for future hurricanes, including Hurricane Milton, which is currently threatening the Florida coast. The study emphasizes the urgent need for improved emergency preparedness and resilience planning as climate change continues to increase the frequency and severity of extreme weather events.
As we face the potential for more devastating storms, the findings serve as a critical reminder of the impact of climate change on our environment and the importance of transitioning away from fossil fuels.
