The Climate Explorer offers graphs, maps, and downloadable data of observed and projected climate variables for every county in the contiguous United States. The tool shows graphs and maps of climate projections for temperature, precipitation, and related climate variables for two possible futures: one in which humans make a moderate attempt to reduce global emissions of heat-trapping gases, and one in which the rate of global emissions continues rising through 2100.
As of January 2020, the Climate Explorer also offers charts showing climate projections for boroughs in Alaska. These charts show results from two global climate models for a high emissions future. As more data for Alaska becomes available, the tool will be upgraded to provide the full suite of historical observations and map tiles for locations in the nation's largest state.
Climate Explorer provides contextualized information for interpreting each of its interactive graphs. Look for the "About the graph" buttons to reveal additional information below the graph. The tool also lets users compare conditions projected for future decades based on two pathways that global emissions might follow. Text explanations in the tool's About page as well as the Glossary and FAQs pages can help people make meaning of the data and envision the conditions projected for the future.
