Frequency and damage from weather and climate hazards are rising. Frequency of and damage from weather and climate hazards rising because global warming, especially for heat waves, droughts, heavy rain, and coastal flooding (not for hurricanes and tornadoes) Current global warming may have little impact on hurricanes.
