This short video discusses where carbon dioxide, the gas that is mainly responsible for warming up our planet and changing the climate, comes from. It discusses how the rise in atmospheric carbon dioxide comes directly from the burning of fossil fuels and indirectly from the human need for energy.

In this learning activity, students use a web-based carbon calculator to determine their carbon footprint on the basis of their personal and household habits and choices. Students identify which personal activities and household choices produce the most CO2 emissions, compare their carbon footprint to the U.S. and global averages, and identify lifestyle changes they can make to reduce their footprint.

This video illustrates how atmospheric particles, or aerosols (such as black carbon, sulfates, dust, fog), can affect the energy balance of Earth regionally, and the implications for surface temperature warming and cooling.

Global Sea Level Rise Scenarios for the United States National Climate Assessment

Global sea level has been steadily rising for decades and is expected to continue. Scientists have very high confidence that global sea level will rise at least another 8 inches and as much as 6.6 feet by 2100, causing significant impacts in U.S. coastal regions.  This report lays out the science and describes possible scenarios to help planners and policy leaders assess the risks.

Global Anthropogenic Non-CO2 Greenhouse Gas Emissions: 1990-2030

This summary report by the U.S. Environmental Protection Agency provides historical and projected estimates of emissions of non-carbon dioxide greenhouse gases (GHGs) from anthropogenic sources. The report provides a consistent and comprehensive estimate of non-CO2 greenhouse gases for 92 individual countries and eight regions. The analysis provides information that can be used to understand national contributions of GHG emissions, historical progress on reductions, and mitigation opportunities.

National Fish, Wildlife and Plants Climate Adaptation Strategy

From the Arctic to the Everglades, impacts like rising sea levels, warmer temperatures, loss of sea ice, and changing precipitation patterns are affecting the species we care about, the services we value, and the places we call home. Federal, state, and tribal partners with input from many other diverse groups from across the nation have worked to develop a common strategy to respond to these challenges.
