In: Climate Change 2013: The Physical Science Basis. Contribution of Working Group II to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, Cambridge University Press, Cambridge, UK, p. IPCC 2007, Summary for Policymakers, in Climate Change 2007: Impacts, Adaptation and Vulnerability.Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns. Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires.
Climate change will also exacerbate a range of risks to the Great Lakes. Extreme heat, heavy downpours and flooding will affect infrastructure, health, agriculture, forestry, transportation, air and water quality, and more. Decreased water availability will have economic and environmental impacts. Extreme heat will affect health, energy, agriculture and more. Sea level rise poses widespread and continuing threats to the region’s economy and environment. Increasing wildfire, insect outbreaks and tree diseases are causing widespread tree die-off. Sea level rise, erosion, inundation, risks to infrastructure and increasing ocean acidity pose major threats. Changes in the timing of streamflow reduce water supplies for competing demands. Many states and cities are beginning to incorporate climate change into their planning. Infrastructure, agriculture, fisheries and ecosystems will be increasingly compromised. Heat waves, heavy downpours and sea level rise pose growing challenges to many aspects of life in the Northeast. and will continue to affect these regions, according to the Third 3 and Fourth 4 National Climate Assessment Reports, released by the U.S. Some of the long-term effects of global climate change in the United States are as follows, according to the Third and Fourth National Climate Assessment Reports:Ĭhange Will Continue Through This Century and BeyondĪn interactive exploration of how global warming is affecting sea ice, glaciers and continental ice sheets worldwide.īelow are some of the impacts that are currently visible throughout the U.S. "Taken as a whole," the IPCC states, "the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time." 1- 2 Future Effects Net annual costs will increase over time as global temperatures increase. The IPCC predicts that increases in global mean temperature of less than 1.8 to 5.4 degrees Fahrenheit (1 to 3 degrees Celsius) above 1990 levels will produce beneficial impacts in some regions and harmful ones in others. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.Īccording to the IPCC, the extent of climate change effects on individual regions will vary over time and with the ability of different societal and environmental systems to mitigate or adapt to change. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities.
