Future Of Climate Change Climate Change Science Us Epa Key u.s. projections. by 2100, the average u.s. temperature is projected to increase by about 3°f to 12°f, depending on emissions scenario and climate model. [1] an increase in average temperatures worldwide implies more frequent and intense extreme heat events, or heat waves. The earth’s climate is changing. multiple lines of evidence show changes in our weather, oceans, ecosystems, and more. epa is committed to providing the most up to date and accurate climate science information, including basics, causes, indicators, and impacts of climate change.
Future Of Climate Change Climate Change Science Us Epa A deeper look: climate change impacts explores impacts by region, sector, and state. climate change indicators tracks the ways our planet is already changing. extreme weather illustrates how these events are linked to climate change. the climate change impacts and risk analysis project analyzes future impacts. Carbon dioxide, methane, and nitrous oxide concentrations are now more abundant in the earth’s atmosphere than any time in the last 800,000 years. 5 these greenhouse gas emissions have increased the greenhouse effect and caused the earth’s surface temperature to rise. burning fossil fuels changes the climate more than any other human activity. Human activities are contributing to climate change, primarily by releasing billions of tons of carbon dioxide (co 2) and other heat trapping gases, known as greenhouse gases, into the atmosphere every year. [1] climate changes will continue into the future. the more greenhouse gases we emit, the larger future climate changes will be. Climate change can also impact human health by worsening air and water quality, increasing the spread of certain diseases, and altering the frequency or intensity of extreme weather events. 3. rising sea level threatens coastal communities and ecosystems. 4. changes in the patterns and amount of rainfall, as well as changes in the timing and.
