Infectious diseases that are carried by insects and other pests are highly sensitive to environmental conditions. Higher temperatures will increase the range of malaria-carrying mosquitoes and make the mosquitoes more infectious. Global warming could cause as many as one-million additional deaths from malaria each year during the middle of the next century. Other sensitive diseases include hantavirus and dengue fever, which has already broken out in Texas. Flooding along our coasts and river basins.
Warmer temperatures cause sea levels to rise and allow the atmosphere to hold more moisture.
In addition to coastal flooding, inland areas can be affected by earlier and more rapid snow melt and more intense storms, leading to greater rates of flooding, such as the ones witnessed last year in North Dakota and Minnesota. Extreme droughts and more severe storms in our heartland. More of our rainfall is now coming in intense downpours rather than steady drizzles. This coupled with higher rates of evaporation in a warmer world is expected to intensify droughts and storm damage in America's breadbasket. The current drought in the Southeast United States is a clear example of this kind of event.
