The Climate Explorer offers climate projections through 2100 for every county in the United States. For the contiguous U.S. and island territories, the tool shows climate projections for temperature, precipitation, and related climate variables for two possible futures—one in which humans make a significant attempt to reduce global emissions of heat-trapping gases (lower emissions), and one in which the rate of global emissions continues rising through 2100 (higher emissions).  For boroughs in Alaska, graphs show projections for a high emissions future from two climate models.

Climate Explorer provides contextualized information for interpreting each of its interactive graphs. Look for the "How to read" buttons to reveal additional information below the graph. Text explanations in the tool's About page as well as the Glossary and FAQs pages can also help people make meaning of the data and envision the conditions projected for the future.
