By examining the frequency of extreme storm surges in the past,
previous research has shown that there was an increasing
tendency for storm hurricane surges when the climate was warmer.
But how much worse will it get as temperatures rise in the
future? How many extreme storm surges like that from Hurricane
Katrina, which hit the U.S. coast in 2005, will there be as a
result of global warming? New research from the Niels Bohr
Institute show that there will be a tenfold increase in
frequency if the climate becomes two degrees Celcius warmer. The
results are published in the scientific journal Proceedings of
the National Academy of Science (PNAS). Tropical cyclones arise
over warm ocean surfaces with strong evaporation and warming of
the air. The typically form in the Atlantic Ocean and move
towards the U.S. East Coast and the Gulf of Mexico. If you want
to try to calculate the frequency of tropical cyclones in a
future with a warmer global climate, researchers have developed
various models. One is based on the
