Hurricane Milton: A Growing Threat Fueled by Climate Change
Earlier this week, Hurricane Milton intensified in the Gulf of Mexico, swiftly reaching Category 5 status, the highest level on the Saffir-Simpson scale. After leaving a path of destruction across the Yucatán Peninsula in Mexico, it is clear that this storm threatens to wreak havoc in Florida, a state still reeling from the aftermath of a previous hurricane.
Hurricane Milton poses a considerable risk to Florida, according to the National Hurricane Center (NHC). "If you stay, you are going to die," warned Tampa Mayor Jane Castor, urging residents to evacuate their homes as the hurricane is expected to have its most significant impact on the city.
This is not the first time Florida residents have received such alarming warnings. Just two weeks ago, Hurricane Helene made landfall in Florida as a Category 4 storm. It moved inland, bringing torrential rains that affected areas as far as Georgia, the western Carolinas, eastern Tennessee, and southern Virginia. The devastating impact of Helene resulted in 227 fatalities, making it the second deadliest hurricane in U.S. history, surpassed only by Katrina in 2005. Furthermore, two million people were left without electricity, and damage from Helene remains unaddressed as Milton approaches.
Bernadette Woods Placky, chief meteorologist at Climate Central, remarked, "This was such a massive event that it flooded almost everything in its path all the way to Ohio, not just the coast," during a press conference for World Weather Attribution (WWA), an organization that studies the role of climate change in extreme weather events.
Scientists have long warned that climate change, driven by human activities, is intensifying hurricanes. A recent study by WWA, while not yet peer-reviewed, employs established methodologies to analyze how this relationship manifested in the case of Hurricane Helene. According to their research, climate change has increased the likelihood of such intense hurricanes occurring in the region by 25 times compared to the pre-industrial era. In essence, a hurricane of this magnitude, previously expected to happen once every 130 years, is now projected to occur every 53 years.
To understand how hurricane dynamics are shifting with global warming, researchers analyzed indices and models related to rainfall patterns, wind, and ocean surface temperatures—critical components in fueling hurricanes. They examined data from coastal and continental regions affected by intense rainfall, finding that precipitation was about 10% heavier due to climate change, with coastal areas seeing rainfall that was 40% more intense. On the mainland, rainfall was 70% more severe over a longer duration. If fossil fuel consumption continues to drive global warming to 2°C above pre-industrial levels, devastating rainfall events in both regions could become 15-25% more likely.
The study also indicated that climate change increased Hurricane Helene's winds by 11%. Additionally, rising ocean surface temperatures in the Gulf of Mexico, which were just above average at the time Helene passed, were 200 to 500 times more likely due to climate change. Notably, Helene's unusual trajectory took it further offshore toward Ohio—a region that lacks the hurricane preparedness necessary to mitigate such a severe threat.
Most of the deaths from this hurricane occurred inland, in mountainous regions where spotty cell and internet service complicated evacuation efforts, leaving many residents feeling caught off guard.
Indeed, climate change is transforming hurricane dynamics, not only in terms of Hurricane Helene but now with the impending threat of Hurricane Milton. An analysis by Climate Central indicated that the high ocean temperatures fueling Milton have become 400 to 800 times more likely due to climate change.
As meteorologist John Morales watched images of Hurricane Milton's alarming progression on live television, his voice cracked as he expressed his concerns: "I apologize. This is just horrific." He fully recognizes the gravity of the situation unfolding before him and anticipates that hurricane seasons in the Atlantic will become progressively more unpredictable.
The growing intensity of storms like Milton and Helene serves as a stark reminder of the ongoing effects of climate change and the urgent need for comprehensive disaster preparedness strategies across vulnerable regions, particularly in hurricane-prone areas like Florida.
Stay informed and take the necessary precautions as Hurricane Milton approaches. It's a precarious time for residents facing an increasingly volatile weather landscape.
