The Intergovernmental Panel on Climate Change (IPCC) says the risk of extreme weather events is likely to increase if the global warming trend continues.
In a special report presented at the IPCC's 34th session, the panel said it was probable that emissions had led to an increase in daily maximum temperatures, the state-funded BBC reported.
"Average tropical cyclone maximum wind speed is likely to increase, although increases may not occur in all ocean basins,” the report noted.
“Small island - as well as mountainous and coastal - settlements were likely to be vulnerable because of sea-level rise and higher temperatures, in both developed and developing nations,”
"Rapid urbanization and the growth of mega-cities, especially in developing nations, have led to the emergence of highly vulnerable urban communities," the IPCC report read.
Climate change has long been a field of scientific research as a factor contributing to more extreme weather events.
IPCC's next assessment report is set to be published in late 2013/2014.
