Climate Change, Hurricanes, and the Real Costs of Rebuilding in Vulnerable Areas
As I watched the devastation caused by Hurricane Helene, the homes submerged, lives upended, and entire communities left in disarray, my heart went out to those facing unimaginable loss.
It’s a stark reminder of the human cost of these natural disasters. But as we confront these tragedies, we must also take a critical look at how we respond to them.
Are we truly addressing the causes, or are we caught in a cycle of rebuilding the same vulnerable areas, only to see them destroyed again?
The recent Hurricane Helene has sparked renewed debate about the relationship between extreme weather and climate change.
FEMA Administrator Deanne Criswell’s remarks, focusing on warming waters and rising storm intensities, reflect the narrative that connects these disasters to global climate trends.
However, the available data on hurricane frequency and historical comparison with the 1916 Appalachian storm complicate this picture and raise questions about how we should respond to such disasters.
Analysis of Administrator Criswell’s Statements
ADMINISTRATOR CRISWELL: Well, I think what we’re seeing, Robert is, you know, this storm took a while to develop, but once it did, it developed and intensified very rapidly, and that’s because of the warm waters in the Gulf and so it’s creating more storms that are reaching this major category level than we’ve seen in the past.
It’s also creating greater amounts of storm surge in the coastal areas. It’s creating greater amounts of rainfall as it moves up north. And so in the past, when we would look at damage from hurricanes, it was primarily wind damage, with some water damage, but now we’re seeing so much more water damage, and I think that is a result of the warm waters, which is a result of climate change.
This view, heavily endorsed by both policymakers and some scientists, asserts that human-driven climate change is the root cause of these escalating natural disasters.
However, historical and meteorological data offer a more complex picture. Despite increasing atmospheric CO2 levels, the frequency of major hurricanes (≥ 96 knots) has fluctuated over time, following a cyclical rather than linear trend.
Meteorologist Dr. Ryan Maue’s data on the 12-month running sums of global hurricane frequency reveals periods of both increases and decreases over the last several decades, questioning the assertion that climate change is the sole or even primary driver behind these storms.
While the number of hurricanes is often used to discuss the impacts of climate change, the frequency of storms does not necessarily indicate whether storms are becoming more intense.
To assess whether hurricanes are becoming stronger, a more reliable metric is Accumulated Cyclone Energy (ACE), which considers both the duration and intensity of tropical storms and hurricanes.
The provided graphic of global and Northern Hemisphere ACE data over the last 50 years illustrates no significant upward trend in cyclone energy. In fact, the data suggest periods of fluctuation but no consistent increase in storm strength.
This implies that while storms like Hurricane Helene might be destructive, there is no clear evidence that climate change is “supercharging” the entire hurricane system. ACE remains a crucial tool in understanding storm power, showing that variability in storm energy, rather than a dramatic intensification, is part of the natural system.
Comparing Hurricane Helene and the 1916 Storm
To provide historical context, it’s essential to compare Hurricane Helene with the 1916 storm that devastated Appalachian towns.
The flood of July 1916 in Asheville, North Carolina, was caused by two back-to-back tropical systems that dumped unprecedented rainfall on the region. This resulted in the most catastrophic flooding in Western North Carolina’s history.
The flood stage at the French Broad River in Asheville reached an astonishing 23 feet, with water levels rising rapidly due to the saturated ground and overwhelming rivers and streams. This flood submerged entire sections of Asheville, destroyed homes, businesses, and railroads, and left significant debris in its wake.
Several towns in the Appalachian region experienced unprecedented destruction, with many areas submerged under several feet of water.
The 1916 storm caused rivers like the Swannanoa to rise over their banks, affecting communities that had little in terms of flood infrastructure.
The total economic toll and loss of life were profound, as the region struggled to recover from the devastation. The 1916 event occured even though atmospheric CO2 levels were approximately 120 ppm lower than they are today.
In comparison, Hurricane Helene caused flooding in Asheville just recently. While the exact numbers may not be finalized yet, NOAA shows that the French Broad River at Asheville reached a peak stage of 24.67 feet following Hurricane Helene.
This crest exceeds the 1916 flood level, which had reached a record of 23.1 feet. This new peak is indicative of the storm’s severity and the risk of significant flooding in the region.
The 1916 event suggests that extreme weather events of similar magnitude occurred long before human-driven climate change became a prominent factor.
Hurricanes are a natural part of Earth’s climatic system, and their occurrence is influenced by a wide range of factors, including natural climate variability and oceanic patterns.
The comparison between these two storms highlights an important point: while the frequency and intensity of hurricanes may fluctuate, they are not unprecedented.
The 1916 storm serves as a reminder that catastrophic weather events have always occurred and will continue to do so, regardless of human activity. This context raises questions about how we should interpret and respond to current events like Hurricane Helene.
Broader Issue: Politicization and Responsibility
This graphic showing Asheville’s population growth from 2000 to 2022 highlights an important factor when considering the impacts of Hurricane Helene and future flood events.
As the population has steadily increased, reaching an estimated 93,776 by 2022, this growth exacerbates the risks associated with flooding.
More people, homes, and infrastructure are now situated in vulnerable areas, increasing the potential for damage during extreme weather events. This steady urban expansion into flood-prone regions, without adequate flood prevention measures, further emphasizes the need for stronger planning and infrastructure solutions.
The rising population, coupled with frequent storms, raises questions about whether the current rebuilding practices in Asheville are sustainable or merely setting the stage for future disasters.
Blaming the fossil fuel industry for all weather-related disasters overlooks the complexity of natural climate variability and the role of poor urban planning in flood-prone regions.
The decision to rebuild in areas that are consistently vulnerable to hurricanes and floods, regardless of atmospheric CO2 levels, raises questions about the efficacy and sustainability of these efforts.
Rather than focusing solely on climate change, there should be greater emphasis on improving infrastructure and disaster preparedness in high-risk areas… or not building in them at all.
Conclusion
The pattern surrounding disaster response and rebuilding efforts raises significant questions about the motives behind certain climate change narratives.
Agencies like FEMA often attribute every significant storm, such as Hurricane Helene, to climate change, and the result is a cycle of taxpayer-funded rebuilding in known flood-prone areas. This process inevitably repeats itself after the next inevitable storm.
The strategy becomes not one of prevention or risk reduction but of securing funds under the guise of climate mitigation.
This approach shifts focus away from improving long-term infrastructure resilience or addressing urban planning issues, making communities even more vulnerable to future disasters.
Instead of perpetually blaming climate change and asking for billions in funding, a more pragmatic solution would involve restricting development in high-risk areas and adopting stronger flood prevention measures, steps that would genuinely protect lives and property without simply waiting for the next crisis to occur.

Hi Matthew,
“Tornadoes associated with tropical systems typically form in the right front quadrant of the storm, relative to the direction of forward motion. If you were looking at the storm like it was a clock, this would be the area from about noon to three o’clock in the direction the storm is moving. While not normally as intense as tornadoes produced by non-tropical severe thunderstorms, these tornadoes often move very fast; at speeds over 50 mph. Another common area of tornadoes in a hurricane is in the far outer rain bands, which can be hundreds of miles away from the center of the storm.” (Florida Climate Center)
The extreme destruction to which you refer were not caused by straight-line hurricane winds, they were caused by tornado swirling winds. Both hurricanes and tornadoes are natural phenomena which have been naturally occurring for centuries and can not be prevented by any human activity any more than earthquakes and volcanic eruptions can be prevented.
Have a good day
