Researchers from Princeton University and the National Oceanic and Atmospheric Administration (NOAA) report in the journal Nature Climate Change that extreme cyclones that formed in the Arabian Sea for the first time in 2014 are the result of global warming and will likely increase in frequency. Their model showed that the burning of fossil fuels since 1860 would lead to an increase in the destructive storms in the Arabian Sea by 2015, marking one of the first times that modeled projections have synchronized with real observations of storm activity, the researchers said.
