Devastating hurricanes tripled in a hundred years

I thought the Mahdi

Hurricanes are one of the most devastating natural disasters, and a new study by the Niels Bohr Institute at the University of Copenhagen warns that hurricanes are more severe than they were before, foreshadowing tremendous destructive power compared to previous hurricanes.

Climate in hurricane calculations
Researchers from the University of Copenhagen have developed a method to calibrate the natural damage caused by hurricanes, where damage is assessed by estimating an area equivalent to the total destruction caused by a hurricane.

This method is distinct from other traditional methods because it depends on climatic factors including atmospheric pressure and wind speeds, allowing researchers to assess the impact of climate on changes in the hurricane scenario.

The findings unequivocally show a significant role for global warming in the increasing frequency of devastating hurricanes that routinely wreak havoc on the south and east coast of North America.

In addition, the frequency of devastating hurricanes has tripled in the last 100 years. The findings were published on PNAS on November 11.

Ignore climatic factors
Traditional methods of assessing and comparing a hurricane are based on the economic damage caused by a hurricane, in order to monitor the development of hurricanes over time, thus scanning the subsequent cost of damage caused by a hurricane.

In other words, these methods calculate the damage caused to infrastructure, changes in wealth and population distribution, but ignore the existence of any climate index associated with the destructive power of the hurricane, and thus did not record accurate statistical data on the climatic conditions that accompanied severe cyclones.

Waiting for more severe hurricanes
Rather than assessing individual hurricane scenarios, the researchers assessed the size of the area that could be considered a "zone of mass destruction," meaning the size of the area that you must completely destroy in order to calculate financial loss, including damage to infrastructure, population distribution and wealth distribution, as well as natural damage. .

Researchers have developed a record of natural damage from hurricanes since 1900 based on an equivalent area of ​​total destruction.

This method has enabled them to compare rural and densely populated areas such as cities, and to study the impact of activity associated with economic growth on climate change in terms of increasing global warming and global warming.

The results of the study show the extent of mass destruction caused by hurricanes, which means an increase in natural damage since 1900, and these results are consistent with climate models that predict that major hurricanes will increase in intensity with global warming.

Researchers recommend the importance of including climatic factors for better risk assessment of hurricanes.
