Since 1989, the U.S. Global Change Research Program (USGCRP) has submitted annual reports to Congress called Our Changing Planet. The reports describe the status of USGCRP research activities, provide progress updates, and document recent accomplishments.

In particular, Our Changing Planet highlights progress and accomplishments in interagency activities. These highlights represent the broad spectrum of USGCRP activities that extend from Earth system observations, modeling, and fundamental research through synthesis and assessment, decision support, education, and public engagement.

The U.S. research centers that develop climate and Earth system models and the U.S. scientific community are key participants in long-running collaborative efforts to improve knowledge on climate change. A number of major interagency activities supporting improvements in climate modeling took place in 2019.

Most prominently, the World Climate Research Programme Coupled Model Intercomparison Project (CMIP) is currently in its sixth phase (CMIP6). The earlier phases of CMIP experiments have provided the research community...

Climate-sensitive infectious diseases, including vector-borne diseases (such as dengue, West Nile Virus, and Chikungunya), waterborne diseases (such as those caused by Vibrio species), soil- and dust-borne diseases (such as Valley Fever), and zoonotic diseases (such as plague and avian influenza) pose threats to the health of Americans living at home and abroad. These threats are anticipated to change in distribution and severity as climate change progresses in the coming decades. Improving U.S. capacity to predict and communicate changes in risks of climate-sensitive diseases,...
