Hurricanes will multiply by ten, if the planet's temperature rises 2º degrees

The frequency of extreme storms or tropical cyclones will increase tenfold if the global temperature rises two degrees Celsius, according to the results of new research from the Niels Bohr Institute of the University of Copenhagen, published in the scientific journal 'Proceedings of the National Academy of Science '.

Tropical cyclones arise over hot ocean surfaces with strong evaporation and warming of the air. The general shape in the Atlantic Ocean and the advance towards the east coast of the United States and the Gulf of Mexico.

If you want to try to calculate the frequency of tropical cyclones in the future with a warmer global climate, researchers have developed several models to calculate the frequency of cyclones with a warmer global climate: one is based on regional sea temperatures and another on the differences between regional sea temperatures and average temperatures in tropical oceans. But there is disagreement about which is better.

"Rather than choosing between the two methods, I have chosen to use temperatures from around the world and combine them into a single model," explains climate scientist Aslak Grinsted, from the Center for Ice and Climate at the Niels Bohr Institute at the University of Copenhagen, which carried out the research with colleagues from China and England. Your system takes into account different statistical models and weights according to how good they are at explaining drastic storm surges.

In this way, the model reflects known physical relationships, for example, how the El Niño phenomenon affects the formation of cyclones. Since 1923, there has been a surge of the magnitude of Hurricane "Katrina" every 20 years.

"We found that a climate warming of 0.4 degrees Celsius corresponds to a doubling of the frequency of extreme storms like Katrina for the next hurricane. With the global warming that we have had during the 20th century, we have already crossed the threshold , where more than half of all 'Katrinas' are due to global warming, "explains Aslak Grinsted.

"If the temperature increases an additional degree, the frequency will increase three to four times and if the global climate increases two degrees, there will be about ten times more extreme storms. This means that there will be an increase in storms of the magnitude of 'Katrina 'every two years,' says Grinsted, who also notes that the sea will rise due to global warming, with consequent worse and potentially more destructive tidal waves.
