Highlights
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. Highlights describe the state of science at the time of publication of each yearly report, and may not reflect more recent advances in understanding. The date of publication of the source report is noted on each highlight page.
A national system of physical, ecological, and societal indicators is considered a foundational component of the sustained assessment process, serving to help users understand the changing environment, assess risks and vulnerabilities, and make informed decisions to build resilience to change. A 2019 Federal–academic workshop sought to advance the development of socio-environmental systems indicators of climate change to support adaptation and resilience decisions at various scales in the United States.
This work was supported by the National Socio-Environmental Synthesis Center (...
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,...
The U.S. Midwest is a major producer of a wide range of food and animal feed for national consumption and international trade. Higher humidity, precipitation, and temperatures associated with a changing climate increasingly impact agriculture in the region, and projected climate changes are expected to pose growing challenges to agricultural productivity in the coming decades.[1]
Weather and climate information targeted to the needs of agricultural producers can help producers increase the resilience of their...
Long-term measurements of Earth’s atmosphere show rapidly rising concentrations of greenhouse gases linked to human activities.[1] Existing observing networks provide information on atmospheric concentrations of greenhouse gases at the global scale, but this spatial scale is not sufficient to help nations, regions, and other entities quantify and manage greenhouse gas emissions. To improve the relevance of emissions information for decision-making, an international initiative is promoting scientific methods that combine...
