WHITE HOUSE FACT SHEET ON PROTECTING OCEAN AND COASTS

FROM:  THE WHITE HOUSE 

FACT SHEET: Leading at Home and Internationally to Protect Our Ocean and Coasts

We’ve already shown that when we work together, we can protect our oceans for future generations.  So let’s redouble our efforts.  Let’s make sure that years from now we can look our children in the eye and tell them that, yes, we did our part, we took action, and we led the way toward a safer, more stable world.”
President Barack Obama, June 17, 2014
President Obama is committed to protecting the ocean and its marine ecosystems. Americans all over the country depend on the ocean for food, jobs, and recreation.  But the health of our ocean is under threat on multiple fronts, from overfishing to carbon pollution.  The recently released National Climate Assessment confirms that climate change is causing sea levels and ocean temperatures to rise. Changing temperatures can harm coral reefs and force certain species to migrate. In addition, carbon pollution is being absorbed by the oceans, causing them to acidify, which can damage coastal shellfish beds and reefs, altering entire marine ecosystems. In fact, the acidity of our ocean is changing 50 times faster than any known change in millions of years. And black market fishing—fishing that is illegal, unreported, and unregulated (IUU)—continues to pose a major threat to the sustainability of our world’s fisheries, economies and to global security.
Recognizing these significant challenges, President Obama launched the National Ocean Policy early in his first term. The National Ocean Policy seeks to streamline more than 100 laws that govern our oceans and create a coordinated, science-based approach to managing the many resources and uses of our coasts and oceans. National Ocean Policy initiatives range from voluntary marine planning to releasing more federal data to supporting offshore renewable energy projects to making our ports more resilient to sea level rise.
This week, the State Department is hosting the “Our Ocean” conference, an international conference on sustainable fisheries, marine pollution, and ocean acidification that concludes today. Secretary Kerry has also issued a global call to action to protect the oceans. As part of the conference, the President is announcing several steps that the United States is taking to answer that call. During the closing events of the conference, the State Department will announce additional steps and commitments it has secured to protect our oceans.
New Actions to Protect and Preserve the Ocean
Today, in a video message to conference participants, President Obama is announcing new executive actions to preserve and protect the oceans.
  • New protections for world-class marine areas. The President today announced a commitment to use his authority to protect some of our most precious marine landscape just like he has for our mountains and rivers and forests.   To meet the President’s commitment, the Administration will immediately consider how we might expand protections near the Pacific Remote Islands Marine National Monument in the south-central Pacific Ocean, an area which contains some of the most pristine tropical marine environments in the world.  These tropical coral reefs and associated marine ecosystems are also among the most vulnerable areas to the impacts of climate change and ocean acidification. Before making decisions about the geographic scope and details of future marine protections, we will consider the input of fishermen, scientists, conservation experts, elected officials, and other stakeholders.  The President is also calling on other world leaders to join him in this effort to ensure that the world’s most valuable ocean ecosystems remain productive and pristine for our children and grandchildren. 
  • Combating black market fishing and supporting fishermen. The President is directing Federal agencies to develop a comprehensive program aimed at deterring illegal fishing, addressing seafood fraud, and preventing illegally caught fish from entering the marketplace by increasing traceability and transparency. Black market fishing constitutes up to 20 percent of the wild marine fish caught each year around the world, and drains up to $23 billion from legitimate fishing enterprises. The program will be an important step in ending illegal, unreported, and unregulated fishing, building the market for legally and sustainably caught seafood, and supporting the men and women of the fishing industry. 
In addition, the Administration is taking steps to protect coastal communities from the impacts of climate change, improve domestic aquaculture, and providing research to better understand the challenges facing our oceans.
  • Establishing a pathway to new marine sanctuaries. Last week, the National Oceanic and Atmospheric Administration (NOAA) released a final rule re-opening the public nomination process for proposing new sanctuaries in our oceans and Great Lakes. For the first time since 1995, Americans will be able to nominate nationally significant marine and Great Lakes areas as marine sanctuaries. This reflects the overwhelming consensus of more than 18,000 comments NOAA received on the proposed version of the rule and will give local communities and organizations the opportunity to voice their support for significant marine areas in need of protection. 
  • Meeting diverse coastal needs with regional marine planning. Under the President’s National Ocean Policy, voluntary marine planning bodies are working all over the country to find commonsense ways for the wide range of people and organizations who live, work, and play in the ocean to enjoy the full benefits of its resources. Regional marine plans help balance coastal use issues including fishing, energy, and marine transportation with the interests of communities, ensuring maximum benefits for all. Last week, the Administration announced that the Northeast and Mid-Atlantic regional marine planning bodies will have their plans out the door by the end of the President’s term. This will allow fishing and coastal communities from Maine to Virginia to meet diverse needs and establish priorities for the use of their ocean areas, while making them less vulnerable to economic shocks and the resilience of climate change.
  • Understanding the impacts of ocean acidification. Today, the White House Office of Science and Technology Policy is releasing a white paper on ocean acidification, summarizing current scientific knowledge about this key challenge, its relationship to climate change, and its impacts on society, as well as highlighting key steps the Obama Administration is taking to better understand the problem and potential solutions. 
  • $102 million to build resilience in coastal communities. Yesterday, the Department of the Interior announced $102 million in competitive grants funding science-based solutions to restore flood plains and natural barriers, such as marshes and wetlands along the Atlantic Coast. The funded projects will help deliver on the Administration’s Climate Action Plan commitment to make local communities more resilient against future storms. 
  • Bolstering domestic shellfish aquaculture. Federal agencies are completing work on a new roadmap to streamline the permitting process for shellfish aquaculture. The roadmap will help shellfish farmers understand how to secure the permits they need and will help federal agencies identify ways to improve efficiency in the permitting process. By removing barriers in the permitting process, the United States can encourage shellfish farming and help rebalance our seafood trade. Currently, most seafood consumed in the U.S. is imported, resulting in a seafood trade deficit of between $8 and $10 billion a year. Farming more shellfish will also be an economic boon to local communities, creating jobs and investment on our shores. 
  • National Strategic Plan for Federal Aquaculture Research. Aquaculture is an increasingly integral source of safe, nutritious, sustainable seafood for consumers in the United States and worldwide. Today, the interagency National Science & Technology Council’s Committee on Science is releasing a new National Strategic Plan for Federal Aquaculture Research to provide a framework for coordination and collaboration across agencies on research related to this important agricultural domain and to guide Federal agencies going forward as they prioritize their aquaculture-related research and development activities.

NSF: RISING SEAS THREATEN WETLANDS

FROM:  NATIONAL SCIENCE FOUNDATION 
Wetlands' ability to overcome sea level rise threatened

When do wetlands reach their limit, and how are we lowering that point?
Left to themselves, coastal wetlands can resist rapid sea level rise.

But humans could be sabotaging some of wetlands' best defenses, according to results published in this week's issue of the journal Nature.

Thanks to an intricate system of feedbacks, wetlands are remarkably good at building up soils to outpace sea level rise. The questions are: When do they reach their limit, and how have we lowered that point?

Without human-caused climate change, "we wouldn't be worried about wetlands surviving the rates of sea level rise we're seeing today," says lead paper author Matthew Kirwan of the Virginia Institute of Marine Science and the National Science Foundation (NSF) Virginia Coast Reserve Long-Term Ecological Research (LTER) site.

Virginia Coast Reserve is one of 26 such NSF LTER sites around the globe in ecosystems from deserts to mountains and marshes to grasslands.

In an unchanged world, "wetlands would build vertically at faster rates," says Kirwan, "or move inland to higher elevations."

The paper's co-author is Patrick Megonigal of the Smithsonian Environmental Research Center.

A wetland is land that's saturated with water, whether permanently or seasonally. The water found in wetlands can be saltwater, freshwater or brackish water. Main wetland types include swamps, marshes, bogs and fens.

Wetlands have developed several ways to build elevation to keep from drowning.

Aboveground, tidal flooding provides one of the biggest assists. When marshes flood during high tides, sediment settles out of the water, adding new soil. As sea level rises and flooding occurs more often, marshes react by building soil faster.

Belowground, the growth and decay of plant roots add organic matter.

Even erosion can work in wetlands' favor, as sediment lost at one marsh may be deposited in another. While a particular wetland may lose ground, the total wetland area may remain unchanged.

But, if a wetland becomes so submerged that its vegetation dies off, these "positive feedback loops" are lost. Similarly, if sediment delivery to a wetland is cut off, that wetland can no longer build soil to outpace rising seas.

"This study reveals the complex, long-term interplay among processes that maintain coastal wetlands in the face of sea level rise," says Saran Twombly, program director in NSF's Division of Environmental Biology, which funds the NSF Virginia Coast Reserve LTER site.

"Humans are newcomers to this delicate balance. The future of a habitat so essential to human well-being depends on how severely we alter it."

For example, groundwater withdrawal and artificial drainage can cause the land to sink, as is happening in Chesapeake Bay.

Because of this subsidence, eight of the world's 20 largest coastal cities have relative sea level rise greater than climate change projections.

Dams and reservoirs also prevent 20 percent of the global sediment load from reaching the coast.

Marshes on the Yangtze River Delta, for example, have survived a relative sea level rise of more than 50 millimeters per year since the 7th century--until the recent building of more than 50,000 dams cut off the supply of sediment and accelerated erosion.

"Tidal marshes are amazing ecosystem engineers that can raise themselves upward if they remain healthy, especially if there is sediment in the water," says Megonigal.

"We know there are limits, however. Those limits are changing as people alter the environment."

SECRETARY KERRY'S REMARKS ON CLIMATE CHANGE AT PACIFIC ISLANDS FORUM

FROM:  U.S. STATE DEPARTMENT 
Remarks at a Meeting of the Pacific Islands Forum
John Kerry
Secretary of State
New York City
September 27, 2013

Welcome, everybody, and thank you for – sorry, I’m a moment late. I apologize. I’m very happy to be meeting today with Marshall Islands President Loeak and with the Samoan Prime Minister Malielegaoi and other Pacific Island leaders. We’re very happy to have all of you here.

This week these leaders and other leaders from around the globe have come to New York during the UN General Assembly to discuss some of the issues of greatest challenge to everybody, life and death issues that impact millions of people around the world. Climate change is one issue that absolutely impacts millions of people around the world, and no one knows just how deeply serious and present, how now this challenge is and its impacts than the people of the vulnerable Pacific Islands. They have experienced both historic droughts and the highest rates of sea level rise in the world.

So the science is clear and irrefutable, and today the Intergovernmental Panel on Climate Change confirmed for the fifth time in 20 years that climate change is real, is happening, and is in large part caused by human activity. The IPCC findings have stressed that if we continue down our current path, the impacts of climate change, including sea level rise, could be even worse than previously expected.

So as we work with our international partners to prepare for the impacts of climate change and the impacts that we’re already witnessing, we have an urgent responsibility to try to work together even harder to be able to change the way we’re doing things. I’ve been following this issue since, what, 1988 when then-Senator Al Gore and I held the first hearings in the United States Senate. And Jim Hansen came before our committee and said climate change is happening now. That was 1988. Everything has confirmed that ever since, but we still have a small window of time to prevent the very worst impacts of climate change from catching up to us. But that window is closing.

So we know that no one nation has the ability to address climate change alone. The United States, which is together with China a large proportion of emissions, if we acted all by ourselves and went to zero tomorrow it wouldn’t do the job. So we all are in this. We all have to figure out how to proceed forward. And between President Obama’s Climate Action Plan and the important Majuro Declaration the Pacific Islands nations signed at the 44th Pacific Islands Forum earlier this month, between those things our countries have made clear our commitments to address what is one of the defining issues of our time. We’re equally committed to working toward a comprehensive UN climate agreement that takes into account the unique circumstances and capabilities of each nation.

I know I also speak for President Obama when I say that I – we stand with the Pacific Islands in the fight against climate change. And I’m looking forward to our discussion today, and most importantly, I’m looking forward to continuing our very important work as we together try to guarantee the future of our nations and indeed the future of the planet.
