The frequency of extreme hurricane rainfall has surged by 300% and its severity has grown by 33%, according to a new report by DeepSky Research.

The study, which analyzed four decades of climate data, also predicts that hurricanes could cost more than $450 billion in the next five years, a 50% increase from the previous five years, according to the carbon removal project developer.

“Many of the impacts of climate change are slow-moving, but some will be devastating in their rapid escalation,” the report’s authors stated. “We will see the impacts of worsening hurricanes not in the next 50 years, but in the next five. This will mean billions of dollars in damages, hundreds of thousands of homes destroyed, and many lives lost. ”

The report highlights that severe hurricane rainfall, which used to occur once every 100 years, is now expected every 25 years. This increase in frequency and severity is causing more destructive flooding and destruction, and is becoming the new normal. The volume of rainfall that fell in one day over the Houston area, for instance, used to be seen once every seven years, but is now expected every three years.

The maximum severity of hurricane rainfall has also increased by 33%, meaning that the worst-case scenario hurricane today is much more damaging than it used to be. Over the past 40 years, hurricanes have caused the most damage of any weather disaster in the U.S., totaling over $1.3 trillion and killing thousands of people, DeepSky Research stated.

DeepSky Research projects losses of more than $450 billion in the next five years across Gulf and South Atlantic coast states due to hurricanes. The projection is based on a proprietary machine learning model which incorporates worsening precipitation trends, historical hurricane damages, observed changes in climate, and increasing population and investment in hurricane-vulnerable areas. Florida and Texas are expected to bear the brunt of these losses.

The report also found that states along the Gulf Coast, including Texas, Louisiana, and Mississippi, should expect the greatest increases in hurricane rainfall severity. Conversely, states on the Atlantic coast such as North Carolina and South Carolina will see smaller increases, the report found.

The research also warns of the increasing risk of power outages caused by hurricanes, particularly in the Houston area. Power outages not only cause immediate damage but also lead to secondary effects like heat exposure and health problems, the report noted.

The findings of the report underscore the urgent need for preparedness and adaptation strategies to mitigate the devastating impacts of worsening hurricanes.
