Richard Feely discusses new findings about how increased carbon dioxide in the atmosphere is making the oceans more acidic, and how that will affect ocean ecosystems and the marine animals that inhabit them.

Human activities, mainly burning fossil fuels, are increasing the concentration of carbon dioxide in our atmosphere, amplifying the natural greenhouse effect.

This is lesson five of a 9-lesson module. Activity explores the effects of climate change on different parts of the Earth system and on human well-being: polar regions, coral reefs, disease vectors, extreme weather, and biodiversity.

Cover of the 2014 National Climate Assessment

National Climate Assessment Released

The third National Climate Assessment, released May 6, provides an in-depth look at climate change impacts on the U.S both now and into the future. It details the multitude of ways climate change is already affecting and will increasingly affect the lives of Americans.

First Federal Ocean Acidification Strategic Plan Released

The Interagency Working Group on Ocean Acidification, of which EPA is a participating agency, has recently released the "Strategic Plan for Federal Research and Monitoring of Ocean Acidification."

NOAA Releases Arctic Action Plan

Climate change is making the Arctic a greener, warmer, and increasingly accessible place for economic opportunity. However, climate impacts such as sea ice loss and rising ocean acidification are straining coastal community resilience and sound resource stewardship. The NOAA Arctic Action Plan report outlines ways for scientists and stakeholders to share their progress regarding this vast, valuable, and vulnerable region.

Assessing the Vulnerability of Fish Stocks in a Changing Climate

NOAA Fisheries and NOAA’s Earth Research Laboratory have finalized a new methodology to rapidly assess the vulnerability of U.S. marine stocks to a changing climate. The methodology uses existing information on climate and ocean conditions, species distributions, and species life history characteristics in order to estimate the relative vulnerability of fish stocks to potential changes in climate.

Navigating Change: Hawaii's Approach to Adaptation

A report based on the Pacific Islands Regional Climate Assessment (PIRCA) was recently presented to the President's Task Force for Climate Preparedness and Resilience. The report examines climate change impacts in Hawaii and also assesses the adaptive capacity of the Pacific Island communities.
