| Storm Surge from Superstorm Sandy in Marblehead, MA |
How many extreme storm surges like that from Hurricane Katrina will there be as a result of global warming?
New research from the Niels Bohr Institute shows that there will be a 10x increase in frequency with a temperature rise of two degrees Celcius. The results are published in the scientific journal, Proceedings of the National Academy of Science, PNAS.
"We find that 0.4 degrees Celcius warming of the climate corresponds to a doubling of the frequency of extreme storm surges like the one following Hurricane Katrina. With the global warming 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.
