Climate, Fisheries, and Protected Resources

Climate change is already having a profound effect on life 
in the oceans. Marine species tend to be highly mobile, and many are moving quickly toward the poles to stay cool as average ocean temperatures rise. These shifts can cause ecological disruptions as predators become separated from their prey. They can also cause economic disruptions if a fish population becomes less productive or moves out of range of the fishermen who catch them.

In addition to getting warmer, the oceans are also becoming more acidic as they absorb about one-half of the CO2 we emit into the atmosphere. This increased acidity can make life difficult for organisms that build shells out of calcium carbonate. This includes not only corals and shellfish, but also tiny organisms like pteropods that form the foundation of many marine food webs.

NOAA Fisheries scientists are working to understand the effects of climate change and ocean acidification so we can minimize the disruptions they cause, adapt to the changes that are coming, and ensure that future generations can enjoy the benefits of healthy marine ecosystems. Here are some of the things we're working on...



Climate-Smart Conservation Guide
Climate change is already affecting the nation’s valuable marine and coastal resources and the communities that depend on them. NOAA Fisheries and partners recently released a new guide to safeguarding our vital natural resources in the face of changing climate and ocean conditions. Developed by a broad collaboration of experts from federal, state, and non-governmental institutions, the new guide offers practical steps for crafting conservation actions to enhance the resilience of the natural ecosystems on which wildlife and people depend.

National Climate Assessment
The 3rd National Climate Assessment confirms that climate change is affecting every region of the United States and key sectors of the U.S. Economy.

The report finds that climate change is not a distant threat: it is affecting the American people already. These findings underscore the need for urgent action to combat the threats from climate change, protect American citizens and communities today, and build a healthy, sustainable future for our kids and grandkids.

Does "Global Warming" Mean it's Warming Everywhere?
No, "global warming" means Earth's average annual air temperature is rising, but not necessarily in every single location during all seasons across the globe. A new climate Q&A explains more about this idea. Read more...

Climate Change and Fisheries
How will we manage fish populations as the climate changes? NOAA Fisheries biologist John Manderson is working on one small piece of the puzzle. Read more...

Sound Science and Climate Change
