Impacts
The EPA Global Warming Site: Impacts section focuses on the potential impacts of global warming or climate change; the section relies heavily on the work of the Intergovernmental Panel on Climate Change. Rising global temperatures are expected to raise sea level, and change precipitation and other local climate conditions. Changing regional climate could alter forests, crop yields, and water supplies. It could also threaten human health, and harm birds, fish, and many types of ecosystems. Unfortunately, many of the potentially most important impacts depend upon whether rainfall increases or decrease, which can not be reliably projected for specific areas.
| Health - The EPA Global Warming Site Health Impacts. Throughout the world, the prevalence of particular diseases and other threats to human health depend largely on local climate. Extreme temperatures can directly cause the loss of life. Moreover, several serious diseases only appear in warm areas. Finally, warm temperatures can increase air and water pollution, which in turn harm human health. |
| Polar Regions - The EPA Global Warming Site High Latitude Impacts. Climate models indicate that global warming will be felt most acutely at high latitudes, especially in the Arctic where reductions in sea ice and snow cover are expected to lead to the greatest relative temperature increases. |
| Mountains - The EPA Global Warming Site Mountain Impacts. Global climate change poses a number of potential risks to mountain habitats, although scientists cannot predict the impacts with confidence. Associated Pages: Western Mountains |
| Forests - The EPA Global Warming Site Forest Impacts. The projected 2 degrees C (3.6 degrees F) warming could shift the ideal range for many North American forest species by about 300 km (200 mi.) to the north. |
| Non-tidal Wetlands - The EPA Global Warming Site: Impacts on Non-tidal Wetlands. Among the most biologically productive lands, wetlands cover approximately 4 to 6 percent of the Earth’s land surface. The high productivity results from the essential characteristic of a wetland: an area that is flooded part of the time but not all of the time. In addition to the high biological productivity, wetlands are important habitat for birds, fish, and other species. Wetlands are also important cleansing mechanisms for preventing pollutants from farms and other activities from running off and polluting rivers, lakes, and streams. |
| Coastal Zones - The EPA Global Warming Site Coastal Zone Impacts. Studies by EPA and others have estimated that along the U.S. Gulf and Atlantic coasts, a one foot (30 cm) rise in sea level is likely by 2050 and could occur as soon as 2025. In the next century, a two foot rise is most likely, but a four foot rise is possible. Associated Pages: South Florida, Chesapeake Bay |
| Agriculture - The EPA Global Warming Site Agricultural Impacts. The success or failure of a harvest has always depended on climate, with the most important factor being a sufficiently moist soil during the growing season. During extended droughts such as the 1930s Dust Bowl, crop failures have been widespread. Some climatologists suggest that such conditions could become more widespread due to the drier soils that may accompany changing climate. Increased heat stress, more frequent flooding, and salinization of soils due to sea level rise could also threaten agriculture in some areas. Associated Pages: Influencing Factors, Potential US Impacts, Uncertainties |
| Birds - The EPA Global Warming Site: Impacts - Birds. Climate change is likely to have both direct and indirect effects on birds. Higher temperatures can directly alter their life cycles. The loss of wetlands, beaches, and other habitat could have an equally important indirect effect, by making some regions less hospitable to birds than those regions are today. |
| National Parks - The EPA Global Warming Site: Impacts on National Parks and Public Lands. The impacts of climate change on public lands differ from the implications elsewhere in two fundamental respects. First, they are often unique: Yellowstone, Yosemite, Everglades, and many other National Parks were created because it was important to preserve these unusual areas in their natural state forever; Blackwater, Edmund Forsythe (formerly Brigantine), Audubon, and other National Wildlife Refuges were once typical of the natural environments in their respective regions, but today provide unique habit within their regions. Second, the importance and public ownership of these areas may present unique opportunities for ensuring their survival as climate changes. |
| State Impacts - EPA Global Warming: State Impacts provides state specific information sheets for the United States; the potential impacts of global warming or climate change are discussed on a state specific basis. Associated Pages: Data Sources |
