The Greater Yellowstone Climate Assessment
Past, Present, and Future Climate Change in
Greater Yellowstone Watersheds

An overview of the Assessment: This first phase of the Greater Yellowstone Climate Assessment presents an in-depth summary of past, recent, and projected future changes in temperature, precipitation, and water in the Greater Yellowstone Area (GYA). The report focuses on climate changes across the GYA and within the major watersheds (see map below).

The Assessment is a multi-phase effort to analyze and communicate climate change and its potential impacts on different sectors in the Greater Yellowstone region. This first phase was produced by a partnership of the region’s universities, federal and state agencies, and non-governmental organizations. The report has undergone rigorous review to ensure that the findings meet the highest scientific standard.

Request and commitment from the Assessment authors: We seek input from the public, contributors, and organizations on this draft report. Our goal is to better assess the value and clarity of its content before its formal release in late June. We commit to read and consider every comment provided by the public, although public comments may or may not be incorporated into the final report.
