The Impacts of Climate Change on the Global Ocean

 

The global ocean covers about 70 percent of the Earth’s surface and acts as its primary reservoir of heat and carbon, absorbing over 90 percent of the surplus heat and about 30 percent of the carbon dioxide (CO2) associated with human activities, and receiving close to 100 percent of fresh water lost from land ice.

With the accumulation of greenhouse gases in the atmosphere, notably CO2 from fossil fuel combustion, the Earth’s climate and its oceans are now changing more rapidly than at any time since the advent of human societies. Society will increasingly face complex decisions about how to mitigate  adverse impacts of climate change such as sea-level rise, ocean acidification, and species loss. Our publications explore the science, policies, and infrastructure needed to understand, manage, and conserve coastal and marine environments and resources.

 

Understanding the Long-Term Evolution of the Coupled Natural-Human Coastal System: The Future of the U.S. Gulf Coast

The U.S. Gulf Coast provides a valuable setting to study deeply connected natural and human interactions and feedbacks that have led to a complex, interconnected coastal system. The physical landscape in the region has changed significantly due to broad-scale, long-term processes such as coastal …

Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals

Marine mammals face a large array of stressors, including loss of habitat, chemical and noise pollution, and bycatch in fishing, which alone kills hundreds of thousands of marine mammals per year globally. To discern the factors contributing to population trends, scientists must consider the …

Marine Protected Areas: Tools for Sustaining Ocean Ecosystems

Although the ocean-and the resources within-seem limitless, there is clear evidence that human impacts such as overfishing, habitat destruction, and pollution disrupt marine ecosystems and threaten the long-term productivity of the seas. Declining yields in many fisheries and decay of treasured …

A Research Review of Interventions to Increase the Persistence and Resilience of Coral Reefs

Coral reef declines have been recorded for all major tropical ocean basins since the 1980s, averaging approximately 30-50% reductions in reef cover globally. These losses are a result of numerous problems, including habitat destruction, pollution, overfishing, disease, and climate change. …

Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean

The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a …

Antarctic Sea Ice Variability in the Southern Ocean-Climate System: Proceedings of a Workshop

The sea ice surrounding Antarctica has increased in extent and concentration from the late 1970s, when satellite-based measurements began, until 2015. Although this increasing trend is modest, it is surprising given the overall warming of the global climate and the region. Indeed, climate …

Deepwater Horizon 5 Years Later

Deepwater_Horizon_offshore_drilling_unit_on_fire_2010Five years ago today, firefighters were struggling in vain to extinguish a fire on the Deepwater Horizon oil rig in the Gulf of Mexico. The blowout of the Macondo well caused the explosion on the Deepwater Horizon oil rig, killing 11 crewmen and igniting a fireball visible from 40 miles away. On 22 April 2010, Deepwater Horizon sank, leaving the well gushing at the seabed and causing the largest oil spill in U.S. waters. It would be nearly three months before the well could be completely killed, during which time, nearly 5 million barrels of oil spilled into the gulf. Reports from the National Research Council, National Academy of Engineering, Institute of Medicine, and Transportation Research Board provided analysis of the spill and guidance for policy making, health care monitoring, and environmental protection. As part of the legal settlements with the companies held responsible, the federal government has asked the National Academy of Sciences to form and administer a 30-year program to enhance oil system safety, human health, and environmental resources in the Gulf of Mexico and other U.S. continental shelf areas where offshore oil and gas exploration and production occur or are under consideration. Reports from the Gulf Research Program focus on research and development, education and training, and environmental monitoring. All are free to download.
