Among specific predictions in the study for the last few decades of this century:
Wet regions will get wetter and drier regions drier:
Global sea levels will rise from 1 to 4 feet, swamping low-lying regions.
Strong storms will become more frequent, causing infrastructures and systems to collapse, similar to what happened in New Orleans during Hurricane Katrina.
Human health will be threatened by extreme weather, wildfires, decreased air quality, threats to mental health, and illnesses transmitted by food, water, and disease-carriers such as mosquitoes and ticks.
Kim Knowlton, co-deputy director of the Natural Resources Defense Council's Science Center and senior scientist in NRDC's health and environment program, said in a press release: "This report shows how climate change's effects are now firmly in the present, posing threats to our health -- and that of our children, and their children.
"Rising temperatures increase the frequency and intensity of dangerous heat waves, worsen illnesses like asthma, contribute to the spread of insects that carry infectious diseases, and fuel more dangerous storms and flooding.
