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.

An image from a new pilot smartphone-based information tool that alerts users in Florida’s central Gulf Coast to potential respiratory hazards from toxic algal blooms.

In the Gulf of Mexico, toxic algal bloom outbreaks (or red tides) occur primarily during the late summer and early fall, and can be harmful to people and ecosystems. One of the most severe red tide outbreaks in a decade hit Florida’s Gulf Coast throughout the summer and early fall of 2018, with widespread adverse impacts that prompted the governor to declare a State of Emergency in mid-August.

In October 2018, a new pilot smartphone-based information resource developed by NASA, NOAA, and state and local partners began alerting users to red tide risks...

USGCRP agencies and interagency groups played a leading role in the development of a Belmont Forum international Collaborative Research Action (CRA) launched in April 2019, focused on issues at the intersection of climate, environment, and human health.

In addition to an international scoping workshop organized by the Interagency Crosscutting Group on Climate Change and Human Health (CCHHG) and International Activities Interagency Working Group (IAIWG) in April 2018, USGCRP member agencies (including NIH, NOAA, and NSF) participated in a year-long,...

Researchers found that reducing aerosol pollution can achieve both direct and indirect health benefits.

Atmospheric aerosols are tiny airborne particles that can dramatically affect the Earth’s climate through their influence on the flow of energy between Earth’s surface and space. Some aerosols have a cooling effect by reflecting solar energy back into space, while other aerosols containing substantial amounts of carbon warm their surroundings by absorbing the sun’s energy, and can also directly harm human health when particles are at ground...

A Spanish language translation of the executive summary of USGCRP’s report The Impacts of Climate Change on Human Health: a Scientific Assessment is now available.

Climate and health assessment information has been shared widely through a number of platforms and formats, including a Spanish translation of the report overview.

In April 2016, the USGCRP released The Impacts of Climate Change on Human Health in the United States: A Scientific Assessment, a groundbreaking report detailing the major risks and vulnerabilities to human health posed by...

The Aedes aegypti mosquito is the primary vector for transmission of the Zika virus.

Interagency science investigated environmental influences on Zika transmission and helped support response efforts.

In February 2016, the World Health Organization declared the Zika outbreak spreading across the Americas since 2015 a Public Health Emergency of International Concern, based on Zika’s previously-unknown association with birth defects. The virus was first discovered in 1947 in Africa and had not previously been found in the Western Hemisphere. By February 2016, the outbreak had spread to 48 countries and territories in the Americas...

A participant using the GLOBE Observer app on their mobile device examines a magnified mosquito larva to determine if it is a disease-carrying species.

Interagency efforts are engaging citizens in forecasting and observation of mosquito threats.

Global Learning and Observations to Benefit the Environment (GLOBE) is an international science and education program that provides students and the public worldwide with the opportunity to participate in data collection and the scientific process and contribute meaningfully to our understanding of the Earth system and global environment. In 2017, the U.S. Department of State (DOS) partnered with NASA to leverage GLOBE in engaging hard-to-reach populations in...

Reducing the Health Risks of Extreme Heat

Awareness surrounding the connection between climate change and human health is growing. USGCRP’s The Impacts of Climate Change on Human Health in the United States: A Scientific Assessment projected a potential increase of “thousands to tens of thousands of premature heat-related deaths in the summer” by 2100, driven by longer, more frequent, and more intense heat waves.

The National Integrated Heat Health Information System (NIHHIS), launched...

Analyzing the Rising Costs of Climate Change to Human Health

In April 2016, USGCRP released The Impacts of Climate Change on Human Health in the United States: A Scientific Assessment (Climate and Health Assessment), a significant advancement in understanding of the impacts of climate change on human health. It strengthens the finding in previous literature that climate change increases health risks for all Americans, that certain populations are particularly vulnerable, and that these threats are likely to increase as climate change progresses. In particular, an annual...

Indicators are measurements or calculations that represent how a complex system is changing over time—for instance, the unemployment rate is an indicator of overall economic health. For the climate system, indicators offer a simple representation of how a highly complex system is changing, providing a benchmark for decision makers that can be used as a gateway into more complex and context-specific information. Indicators allow multiple audiences—including scientists, planners, policy makers, educators, and the public—to better understand and communicate the causes and effects of climate...

Like many developing countries, India faces a disproportionate share of adverse impacts from climate change, including the exacerbation of its already substantial public-health challenges. The government of India has recognized health as a priority area in its climate-adaptation strategy, and many states now include initiatives related to health in their climate action plans; however, internal public-health capacity for climate-change adaptation is limited. The National Institutes of Health, with support from NOAA and the Department of State, collaborated with organizers in India to host a...
