Climate change in Georgia encompasses the effects of climate change, attributed to man-made increases in atmospheric carbon dioxide, in the U.S. state of Georgia.
Studies show that Georgia is among a string of "Deep South" states that will experience the worst effects of climate change, with effects including "more severe floods and drought", and higher water levels "eroding beaches, submerging low lands, and exacerbating coastal flooding".
The United States Environmental Protection Agency states: "In the coming decades, Georgia will become warmer, and the state will probably experience more severe floods and drought. Even today, more rain is falling in heavy downpours, and sea level is rising about one inch every decade. ... Like other southeastern states, Georgia has warmed less than most of the nation during the last century. But during the next few decades, the changing climate is likely to harm livestock, increase the number of unpleasantly hot days, and increase the risk of heat stroke and other heat-related illnesses".
"Sea level is rising more rapidly in Georgia than along most coasts because the land is sinking. If the oceans and atmosphere continue to warm, sea level is likely to rise one to four feet in the next century along the coast of Georgia. Rising sea level submerges wetlands and dry land, erodes beaches, and exacerbates coastal flooding".
"Changing the climate is likely to increase the severity of both inland flooding and droughts. Since 1958, the amount of precipitation falling during heavy rainstorms has increased by 27 percent in the Southeast, and the trend toward increasingly heavy rainstorms is likely to continue. Rising temperatures are likely to increase the demand for water but make it less available. Warmer temperatures increase the rate at which water evaporates (or transpires) into the air from soils, plants, and surface waters. Because irrigated farmland would need more water, the total demand for water is likely to increase 10 to 50 percent during the next half century. But the amount of available water is likely to decrease, and soils are likely to become drier in most of the state, except along the coast".
"As temperatures rise, less water is likely to flow into the Chattahoochee and other major rivers. Decreased river flows can lower the water level in Lake Lanier and other reservoirs, which may limit municipal water supplies for Atlanta and other cities. Lower water levels may also impair ecosystems, swimming, and other recreational activities, and reduce hydroelectric power generation".
