Humans and Marine Ecosystems

The ocean is central to the health of the planet and the well-being of human societies – sustaining livelihoods and supporting abundant and diverse marine life and ecosystems. Human activity threatens marine ecosystems through relentless overfishing, habitat disruption, and pollution. Our publications explore the negative impacts of human interaction and science and innovation to guide efforts to defend and sustain these valuable resources.

Review of Fate, Exposure, and Effects of Sunscreens in Aquatic Environments and Implications for Sunscreen Usage and Human Health

Regular use of sunscreens has been shown to reduce the risk of sunburn and skin cancer, and slow photoaging of skin. Sunscreens can rinse off into water where people are swimming or wading, and can also enter bodies of water through wastewater such as from bathing or showering. As a result, the …[more]

For Earth Day, Resources to Communicate the Science of Climate Change

The impacts of human activities—particularly emissions of carbon dioxide, but also including other greenhouse gas emissions, land use, and population growth—are so vast that they will largely control the future of the Earth’s climate system. This future could bring a relatively mild change in climate, or it could deliver an extreme change from today’s climate to entirely different climate conditions that will last many thousands of years. The eventual course of the climate system over millennia will be determined largely by the actions taken this century by governments, businesses, and individuals around the world.

Earth and its residents are entering a new geological epoch—the Anthropocene—in which human activities are a primary force affecting climate. Our actions this century to reduce or increase greenhouse gas emissions will determine whether the Anthropocene is a relatively mild event or a severe transition extending over many thousands of years.

Society is beginning to make important choices regarding future greenhouse gas emissions. Climate Stabilization Targets: Emissions, Concentrations, and Impacts over Decades to Millennia considers the projected climate changes and impacts that would occur if greenhouse gases in the atmosphere were stabilized at particular concentration levels. While this book does not recommend or justify any particular stabilization target, it does provide important scientific insights about the relationships among emissions, greenhouse gas concentrations, temperatures, and impacts.

The books from the America’s Climate Choices series address the serious and sweeping issues associated with global climate change, including the science and technology challenges involved, and provide advice on actions and strategies the nation can take to respond. Advancing the Science of Climate Change, Limiting the Magnitude of Future Climate Change, Adapting to the Impacts of Climate Change, and Informing an Effective Response to Climate Change are an authoritative set of analyses to inform and guide responses to climate change across the nation.

These books and others from the National Research Council are available to read online at no charge. The catalog pages for these books contain links to videos and other materials that are great teacher resources. If you teach at the undergraduate or graduate level, visit www.nap.edu/contact.html to request an examination copy of these or any other titles that you feel would be appropriate to use as a textbook for a course.

Science for Climate Change Decision-Making

Earlier this month the World Meteorological Organization announced that the year 2010 is almost certain to rank among the top three warmest years since the beginning of instrumental climate records in 1850. WMO’s data show that 2001-2010 is the warmest ten-year period on record. In November WMO reported that concentrations of the main greenhouse gases have reached their highest levels recorded since pre-industrial times.

This year, the National Research council produced a number of studies that directly address climate change and its effects. Advancing the Science of Climate Change reviews the current scientific evidence regarding climate change and examines the status of the nation’s scientific research efforts. It also describes the critical role that climate change science, broadly defined, can play in developing knowledge and tools to assist decision makers as they act to respond to climate change. The report explores seven cross-cutting research themes that should be included in the nation’s climate change research enterprise, and recommends a number of actions to advance the science of climate change—a science that includes and increasingly integrates across the physical, biological, social, health, and engineering sciences.

Advice on prudent short-term actions and long-term strategies to deal with the effects of climate change can be found in the companion reports Limiting the Magnitude of Future Climate Change, Adapting to the Impacts of Climate Change, and Informing an Effective Response to Climate Change.These titles and others from the Board on Atmospheric Sciences and Climate provide information and direction for research and decision making.
