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.

Harmful algal blooms, or HABs, occur when colonies of cyanobacteria grow to a much greater size and density than normal, resulting in negative effects on water quality, ecosystem health, and the health of humans and animals. Climate-related factors contribute to HABs, including water temperatures and the frequency and intensity of extreme events such as intense storms, both of which are affected by climate change. The impacts of climate change are expected to further increase risks from HABs in recreational and drinking water sources in the coming decades....

Most regions of the United States are projected to experience a higher frequency of severe droughts and longer dry periods as a result of a warming climate.[1] In 2016, USDA Forest Service (USDA-FS) scientists and partners prepared a state-of-the-science synthesis of drought effects on the nation’s forests designed to inform drought resilience and adaptation efforts. A new volume released in 2019 builds on that work, linking recent scientific...

USGCRP’s International Activities Interagency Working Group (IAIWG) convened its first international and interagency workshop in December 2018, bringing together representatives from System for Analysis, Research and Training (START), Future Earth, and the World Climate Research Programme (WCRP). These three international programs receive funding through USGCRP to support their activities and to advance USGCRP’s international mandate. USGCRP was represented by ten Federal agencies as well as USGCRP staff. The workshop’s goals were to enhance awareness of mutual priorities, investments, and...
