In December 2021, the U.S. Committee on the Marine Transportation System issued the third report in a series about the response and resilience of the Nation’s marine transportation system after major hurricanes. The report assessed the impacts to ports from the 2020 hurricane season, which saw a record-breaking number of storms form in the Atlantic basin during a global pandemic. Three storms were examined in-depth: Hurricanes Laura, Sally, and Delta. The report was authored by the Marine...

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.
U.S. coastlines are experiencing more frequent and severe coastal flooding, both recurrent tidal flooding events and life-threatening storm surge events. NOAA and DOT have initiated four four-year projects to investigate the effects of coastal flooding on surface transportation infrastructure. The projects are advancing modeling approaches that evaluate how effective different infrastructure designs are at reducing the impacts of repeated coastal flooding events, pairing pavement deterioration modeling with coastal flood and ecosystem modeling. Research teams are engaging with community...
A new scientific assessment provides information on the spread and control of invasive species for land managers.
The spread of invasive species is recognized as a major driver of biodiversity loss and a source of substantial economic and environmental damage. Global environmental changes, including climate change and land use change, continue to influence how invasive species spread and interact with ecosystems, presenting new and ongoing challenges for land managers. A recent USDA Forest Service (USDA-FS) ...
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...
Interagency efforts are supporting preparedness and safety measures for critical transportation infrastructure.
Dust storms in the Southwest can create dangerous and deadly driving conditions, reducing visibility to near zero with very little warning. Interstate 10 is especially vulnerable to dangerous dust-related driving conditions as it passes through a dry lake bed west of Lordsburg near the Arizona border. To help reduce dust-related risks, the NOAA Regional Integrated Sciences and Assessments (RISA) program and the DOT Federal Highway Administration coordinated with...
Water resources in the United States are affected by a number of climate stressors—including increasing temperatures, changing precipitation patterns, and extreme events like storms and droughts—and these changing conditions have implications for drinking water and stormwater utilities. Federal agencies are working with one another and with state and local partners to build preparedness and sustainability in this essential sector. For instance, the Federal Support Toolbox—grown out of an initiative led by the U.S. Army Corps of Engineers (USACE)—serves as a
Drought is a significant hazard for the United States, with potentially severe and long-lasting impacts on the Nation’s economy and food and water supplies. USGCRP agencies are advancing our understanding of the causes and consequences of drought, an FY 2015 interagency research priority (see Section 4). They are also collaborating in efforts to support drought preparedness and recovery, such as the National Drought Resilience Partnership (a deliverable of the President’s Climate Action Plan) and the National Integrated Drought Information System (NIDIS).
