Hawaii coral recovery efforts progress as Trump pulls support from Paris accord

June 5, 2017 — President Donald Trump’s decision Thursday to withdraw the United States from the Paris climate accord will hamper efforts to stem global warming throughout the world — the primary cause of rising ocean temperatures that pose the single greatest threat to Hawaii’s marine ecosystems.

Responsible for more CO2 emissions than any country save for China, the United States’ exit from the Paris agreement was met with dissension not only from some within Trump’s own administration but also from environmental activists, business leaders across the country and political leaders across globe.

Scientists in Hawaii also balked at Trump’s move, saying the state will not escape the subsequent ripple effect as it works to mitigate environmental impact to coral reefs on the heels of back-to-back years of coral bleaching in 2014 and 2015, the latter of which was part of the third global bleaching event in history.

“If we don’t solve the global emissions (problem) … everything that we do on reefs is substantially harder,” said Thomas Oliver, ocean acidification program manager with the Pacific Islands Fisheries Science Center. “The Paris accord so far represents the best international response we’ve ever had to deal with the problem.”

Dr. Bill Walsh, West Hawaii aquatic biologist for the Hawaii Division of Aquatic Resources, said concerns extend beyond a departure from the Paris agreement to the administration’s general attitude toward climate change and the federal agencies tasked with combating it.

“Even apart from the Paris accord, if the withdrawal or rather the attack of the administration on scientific organizations (like) NOAA or the Environmental Protection Agency — we work hand in hand with them,” he said. “A lot of our ability to effectively monitor the reefs over these years has been due to money the state gets directly from NOAA. We’re all sort of intertwined here.”

Walsh and Oliver each helped develop the Coral Bleaching Recovery Plan, a detailed report synthesizing input from international and local experts along with relevant scientific literature on the problem.

Released in March after roughly a year of work, the strategies the report recommends revolve around establishing networks of no-take Marine Protected Areas (MPAs) and Herbivore Fishery Management Areas (HFMAs).

Strategies also include spatial management of coral reef areas with inherent resiliency to bleaching or a high potential for recovery from bleaching. The final recommendation involves increased enforcement.

Maine’s climate already changing, with more to come

June 2, 2017 — Though people tend to talk most about climate change during a heat wave or in the wake of a terrible storm, the reality is that it’s a slow, subtle shift that’s scarcely noticeable except over the long haul.

But scientists say that Maine is very much feeling its impact.

From a rise in the number of ticks to the decline in the number of northern shrimp offshore, the state is seeing the consequences of an increase in the average annual temperature by 3 degrees since 1895.

The frequency of extreme weather events, from ice storms to torrential rains, has been increasing and will likely to become even more common as the world heats up further, scientists warn.

The accompanying rise in ocean levels, caused by melting glaciers, means that salt marshes are in trouble, flood zones are growing and agricultural zones shifting.

And some say it will get worse if the country fails to take action on climate change.

“Maine is especially vulnerable to the impacts of climate change, where our environment and economy are so closely linked,” said Lisa Pohlmann, the Natural Resources Council of Maine’s executive director.

“Rising sea levels will flood our coastal towns, smog from upwind states will harm the lives of those with asthma, fast-warming waters in the Gulf of Maine will put commercial fisheries at risk, and warming weather threatens vital elements of our economy, like skiing, maple syrup production and ocean fisheries,” she said in a written statement.

A 2015 study by the Climate Change Institute and Maine Sea Grant at the University of Maine that updated an earlier state report on the issue lays out a troubling scenario for a state that depends heavily on tourism, recreation, logging, farming and fishing — all of which are likely to feel the pinch if scientific projections of what’s to come prove prescient.

Already, though, historical data shows warming trends.

For instance, information from the U.S. Climate Divisional Dataset cited by the University of Maine study shows the state’s warm weather season is two weeks longer now than it was a century ago. It’s 34 weeks now, records indicate, compared to 32 in the two decades leading up to World War I.

Data crunchers work to build comprehensive Alaska salmon database

June 2, 2017 — Scientists are gathering temperature data to determine what warming waters mean for salmon.

There’s still a lot scientists don’t know and it’s become a hot topic.

One of the first studies in Alaska was published in the Canadian Journal of Fisheries and Aquatic Sciences this month, as  part of a larger effort to design a statewide database on all things salmon.

The five-year study collected stream and temperature readings in 48 non-glacial streams every 15 minutes to capture high and low temperatures every hour.

Cook Inlet Keeper science director Sue Mauger led the effort and has been working for over a decade monitoring temperatures in salmon streams on the Kenai Peninsula.

Her results provide a baseline for salmon habitat in the Cook Inlet Basin.

“This kind of information that’s on a large regional scale but is site specific gives us that real important tool to decide where should we do one type of protection or conservation activity versus another kind of development  project,” she said.

Mauger studied multiple streams in a single watershed, streams fed by wetlands, lakes and at high and low elevations.

All of these factors play into how susceptible each stream is to climate change, which she said is a concern.

West Coast Ocean Acidification Rates Among Highest In World

June 2, 2017 — Carbon emissions aren’t just causing climate change, they’re having a profound effect on ocean chemistry.

Our oceans are becoming more acidic and this is a major threat to fisheries.

Researchers have now recorded some of the highest levels of ocean acidification in the world,  right off the coast of the Pacific Northwest.

When oceans absorb carbon, they become more acidic, preventing oysters and tiny marine snails at the base of the food chain from forming shells.

A new study from Oregon State University documents ocean acidification off the coast of California and Oregon.

“What we didn’t know is that if you’re an animal living on the shore, how often do you see a bad day?” Francis Chan, a lead author, said. “And now because we have sensors that are actually taking a measurement of ocean PH every 10 minutes throughout the summer, we can start to build that picture.”

The study found that while there were persistent hotspots of destructive acid levels, there were also areas that stayed within healthy ranges.

Maine scientists, academics condemn Trump’s decision on climate accord, see consequences for state

June 2, 2017 — Maine scientists, academics and physicians were dismayed by President Trump’s decision Thursday to withdraw from the Paris climate accord, saying his action will endanger the health of Mainers and harm the state’s fisheries and agriculture.

The move will make the United States look ridiculous in the eyes of world leaders who are trying to effect change, one prominent scientist said.

“China and Europe will become the heroes and we will look like fools,” said Paul Mayewski, director of the Climate Change Institute at the University of Maine.

Mayewski has led more than 55 expeditions to some of the remotest polar and high-altitude locations on Earth, has been published in more than 450 scientific publications, and led climate-change research programs in Antarctica, Greenland and Asia.

Mayewski said that while countries such as China are taking steps to reduce carbon emissions, the U.S., under Trump’s leadership, stands to lose credibility because it remains the second-largest producer of carbon dioxide in the world. He noted that Syria and Nicaragua were the only countries that did not sign the Paris climate agreement.

“We’re giving up, at least politically, the high road on being a leader in climate change,” he said.

Mayewski said Mainers could be harmed by the president’s decision. As temperatures continue to rise and weather patterns become more unstable, extreme heat will make more people vulnerable, especially the sick and the elderly. Climate change also will impact tourism and lobstering, Mayewski said. Health care costs also could increase.

Maine environmental advocates warn of ‘crippling’ cuts in Trump budget

May 26, 2017 — President Donald Trump has not backed off on a wide range of federal budget cuts and program eliminations that critics have for months warned would devastate Maine’s economy and environment.

The cuts to discretionary programs would disrupt scientific research and social services, hack funding to public broadcasting and Maine universities and scientific research institutions, and disrupt the economic prospects of fishing, forestry and former mill communities.

“It’s pretty much a full-on attack on environmental protection in America and would have a crippling impact here in Maine, because we depend so heavily on clean air, clean water, and a brand identity that is defined by our environment,” says Pete Didisheim, advocacy director at the Natural Resources Council of Maine. “There hasn’t been any positive motion with this final budget, if anything it’s gotten slightly worse.”

If the White House has its way, it would mean the end of the University of Maine’s Sea Grant program – which provides research and technical expertise to fishermen and other marine trades – the likely closure of the Wells Reserve at Laudholm Farm, the end of a successful partnership program to clean-up Casco Bay and beach water quality testing statewide.

Pine Tree Legal Assistance, which provides legal aid to indigent citizens to pursuit civil suits and whose volunteers helped uncover the national “robo-signing” mortgage scandal, would lose its funding from the federal Legal Services Corporation, which is also slated for elimination.

Warming water threatens fishing ports

May 22, 2017 — The continued warming of the Gulf of Maine is expected to pose additional threats to the region’s commercially important species of seafood — and by extension to the fishing communities that harvest them, according to a new study.

The study, jointly compiled by researchers at NOAA’s Northeast Fisheries Science Center and the Nature Conservancy, draws the link between the region’s unprecedented warming and concerns about the ability of species to find new, sustainable habitats.

“These changes will directly affect fishing communities, as species now landed in those ports move out of range, and new species move in,” said the authors of the study that appears in journal Progress in Oceanography.

The migration of a spectrum of species could create “economic, social and natural resource management challenges” throughout the region, according to the study.

“The projections indicate that as species shift from one management jurisdiction to another, or span state and federal jurisdictions, increased collaboration among management groups will be needed to set quotas and establish allocations,” the researchers concluded. 

At the heart of the concern is the startling rate at which the Gulf of Maine is warming.

Previous research has shown the region’s surface waters are warming faster than 99 percent of the Earth’s oceans and the study’s researchers project the region will continue to warm “two to three times faster than the global average through the end of this century.”

Gulf of Maine will become too warm for many key fish, report says

May 22, 2017 — A new study by federal fisheries scientists predicts the warming of the Gulf of Maine will cause a dramatic contraction of suitably cool habitat for a range of key commercial fish species there. On the other hand, lobsters are more likely to find hospitable areas.

The study by seven scientists at the National Oceanic and Atmospheric Administration’s Northeast Fisheries Science Center in Woods Hole, Massachusetts, used a high-resolution global climate model and federal fisheries survey data to model how key fisheries species would likely be affected by predicted warming over the next 80 years.

The results confirmed previous research using other models and methods that found that the Gulf of Maine can be expected to become increasingly uncomfortable for many of the cold-loving species that have thrived here for all of recorded history but are at the southern ends of their ranges. Those include cod, haddock, redfish, plaice and pollock.

“The main message here is how important it is to understand the potential magnitude of the changes that you see when you get a finer, higher-resolution view of the implications of changing sea temperatures,” says co-author Michael Fogarty, chief of the ecosystem assessment program at the Northeast Fisheries Science Center.

The scientists caution that the research analyzes just one factor – albeit an important one – the distribution of thermally appropriate habitat for each of 58 species. Their results predict the changes in the amount and location of such habitat but don’t account for many other factors that can influence the future populations of the species themselves, such as what happens to what they eat or what likes to eat them, or how the increasing acidity of the ocean – another product of climate change – will affect each.

ASMFC American Lobster Board Approves 5% Increase in Egg Production for the Southern New England Lobster Stock

May 11, 2017 — The following was released by the Atlantic States Marine Fisheries Commission:

ALEXANDRIA, Va. – The Atlantic States Marine Fisheries Commission’s American Lobster Management Board approved moving forward with the goal of increasing egg production for the Southern New England (SNE) stock of American lobster by 5%. This increase in egg production can be achieved through a suite of management tools including gauge size changes, trap reductions, and seasonal closures. The recreational fishery is only subject to changes in the gauge size should any be proposed. In making its decision, the Board took into consideration the extensive public comment, which overwhelmingly supported status quo, and the fact that stock declines are largely a result of climatic changes, including increasing water temperatures over the last 15 years.

The next step in the process will be for the Lobster Conservation Management Teams (LCMTs) in Areas 2, 3, 4, 5 and 6 to develop area-specific proposals on how to achieve the 5% increase in egg production.  As established through Amendment 3 to the Interstate Fishery Management Plan for American Lobster, LCMTs are composed of lobster industry members who are charged with recommending area-specific measures for Board consideration and approval. The LCMT proposals will be submitted for Technical Committee review in June and Board consideration in August. Once area-specific measures have been approved, the Board will consider final approval of Addendum XXV.

In its deliberation on the SNE lobster stock, the Board discussed the need to consider changes to the current management goals and reference points, noting changes in the marine environment may limit the ability to rebuild the stock to levels seen in the 1990s. The Board will continue to discuss these issues, particularly as the Commission’s Climate Change Work Group develops recommendations regarding the management of stocks impacted by changing climate conditions.

Decades of trawl surveys help Bering Sea climate change research

May 9, 2017 — There’s a new tool to help scientists and others interested in monitoring how Bering Sea fisheries respond to a changing climate.

Biologist Steve Barbeaux of the Alaska Fisheries Science Center has created hundreds of graphics mapping where 22 species of fish spend their time during different life stages.

The data comes from annual trawl surveys dating back to 1984, but Barbeaux says that information was hard to analyze as a whole.

“To understand the true impacts of climate change we have to look across all of these life stages to get a true picture of what’s going on,” Barbeaux said. “It potentially could be beneficial at one stage of life, but harmful at another stage of it’s life.”

Barbeaux started small — looking at greenland turbot, a species that is greatly impacted by temperature changes. When the fish develop from larvae to juveniles, they depend on a cold pool in the Bering Sea. But without it:

“You get high natural mortality,” Barbeaux said. “So for [the greenland turbot] the impact really is at that settlement stage. Versus pollock where that impact has more potentially to do with their midlife stage.”
