As seas rise, city mulls a massive sea barrier across Boston Harbor

February 21, 2017 — It would be a massive, highly controversial wall sure to cost billions of dollars. But this barrier would be much closer to home — and potentially more expensive — than the one President Trump has proposed along the Mexican border.

As rising sea levels pose a growing threat to Boston’s future, city officials are exploring the feasibility of building a vast sea barrier from Hull to Deer Island, forming a protective arc around Boston Harbor.

The idea, raised in a recent city report on the local risks of climate change, sounds like a pipe dream, a project that could rival the Big Dig in complexity and cost. It’s just one of several options, but the sea wall proposal is now under serious study by a team of some of the region’s top scientists and engineers, who recently received a major grant to pursue their research.

With forecasts indicating that Boston could experience routine flooding in the coming decades, threatening some 90,000 residents and $80 billion worth of real estate, city officials say it would be foolish not to consider aggressive action, no matter how daunting.

Maine’s coastal waters are unhealthy from carbon, acidity. Are seaweed gardens the answer?

February 6, 2017 — Seaweed cultivation has been promoted in recent years in Maine as a way to produce local nutritious food and to boost the coastal economy.

Now, seaweed harvesters say their industry provides yet another benefit: environmental protection, in the form of improving water quality.

A new study from Bigelow Laboratory for Marine Sciences in Boothbay indicates growing and harvesting seaweed may be an antidote for increasing carbon and acidity levels in the ocean, which is harming a variety of marine life.

Since January 2016, the lab has been studying the effect of kelp growth on surrounding carbon levels at the Ocean Approved seaweed farm off Great Chebeague Island in Casco Bay.

The early results indicate that sugar kelp absorbs carbon from the surrounding water as it grows. This is prompting the lab to expand its research on kelp and to conduct a separate study on the carbon-absorption abilities of wild-grown rockweed.

Trump’s administration causes concerns at the Alaska Marine Science Symposium

January 27, 2017 — ANCHORAGE, Alaska — Dozens of scientists are meeting this week in Anchorage to talk climate change, fisheries, marine mammals and more, during the annual Alaska Marine Science Symposium; however, this year the climate is a little bit different.

“There’s a palpable fear that scientists are concerned about the way that this administration views science in general,” said Sean McDonald, who is attending the conference from the University of Washington. “We think of science as important.”

During President Donald Trump’s first week in office, he has signed an executive order to shrink the federal workforce – a move that prospective scientists say could hamper their careers.

“Last week, I was actually looking at several federal jobs,” said Shea Steingass, a student at Oregon State University. “I’m planning to complete my Ph.D., in December. And with the hiring freeze, that completely shut that aspect down of my ability to apply for those.”

Warming Signs: Climate Change Means A Sea Change for Fishermen and Scientists

January 23, 2017 — Lobsters used to lurk in the waters of Long Island. But these days, New York fisherman have trouble finding any—while their peers 500 miles away in Maine are seeing bumper crops. Instead, the lobstermen of Long Island now catch more crabs and other shellfish—which, in turn, leaves crabbers further down the East Coast worried about the future of their own livelihoods.

Last week I wrote about how climate change is prompting a fish migration that will directly affect what’s served—or not served—for dinner. But these rapid marine changes won’t just affect our appetites; they also represent a sea change for the fisherman and communities that depend on the sea for jobs and income.

Fishing Regulations Struggle to Catch Up

Of course, catching new fish in your usual fishing haunt is trickier than just changing your bait. Regulations guide what you may catch and how much of it, usually state by state—and they aren’t changing as fast as the environment is. John A. Manderson, a research biologist at the NOAA (the National Oceanic and Atmospheric Administration), noted that sea creatures are moving north 10 times faster than their land-based animals.

“Our ideas of property rights and laws are purely land-based,” Manderson told The New York Times. “But the ocean is all about flux and turbulence and movement.”

To get around these increasingly obsolete laws, some fishermen are catching fish further north and then traveling to areas where it is legal to bring large quantities to shore. Such slippery adherence to regulations sparked mackerel wars in the North Sea back in 2010, and the dispute wasn’t settled for four years.

Furthermore, such an expensive round-about the law is not an option for everyone, especially those with smaller fishing operations.

New England’s 1816 ‘Mackerel Year’ and climate change today

January 19, 2017 — Hundreds of articles have been written about the largest volcanic eruption in recorded history, at Indonesia’s Mt. Tambora just over 200 years ago. But for a small group of New England-based researchers, one more Tambora story needed to be told, one related to its catastrophic effects in the Gulf of Maine that may carry lessons for intertwined human-natural systems facing climate change around the world today.

In the latest issue of Science Advances, first author and research fellow Karen Alexander at the University of Massachusetts Amherst and 11 others including aquatic ecologists, climate scientists and environmental historians recount their many-layered, multidisciplinary investigation into the effects of Tambora on coastal fish and commercial fisheries.

Alexander says, “We approached our study as a forensic examination. We knew that Tambora’s extreme cold had afflicted New England, Europe, China and other places for as long as 17 months. But no one we knew of had investigated coastal ecosystems and fisheries. So, we looked for evidence close to home.”

In work that integrates the social and natural sciences, they used historical fish export data, weather readings,  and town growth chronologies and other sources to discover Tambora’s effects on the Gulf of Maine’s complex human and natural system.

The 1815 eruption caused a long-lasting, extreme climate event in 1816 known as the “year without a summer.” As volcanic winter settled on much of the Northern Hemisphere, crops failed, livestock died and famine swept over many lands. In New England, crop yields may have fallen by 90 percent. The researchers found that 1816 was also called “the mackerel year,” a clue to what they would find regarding fisheries.

Besides Tambora’s climate effects, the authors examined other system-wide influences to explain observed trends. These included historical events such as the War of 1812, human population growth, fish habitat obstruction due to dam building and changes in fishing gear that might have affected fisheries at the time. Employing historical methods in a Complex Adaptive Systems approach allowed them to group and order data at different scales of organization and to identify statistically significant processes that corresponded to known outcomes, Alexander says.

Sen. Whitehouse Mentions RI Fishermen During Pruitt Hearings

January 19, 2017 — WASHINGTON — U.S. Sen. Sheldon Whitehouse quizzed President-elect Trump’s nominee for Administrator of the Environmental Protection Agency about his support for Rhode Island fishermen.

During Senate hearins today, Whitehouse asked Oklahoma Attorney General Scott Pruitt if “he would support the fishing and aquaculture industries in the face of climate change, and whether he would protect Rhode Islanders from out-of-state polluters.”

“As we discussed when you and I met, the oceans off our Ocean State are warming due to fossil fuel-driven climate change,” said Whitehouse. “It is crashing our fisheries, like lobster and winter flounder, and making earning a living harder for our fishermen. I see nothing in your career to give those fishermen any confidence that you will care one bit for their well-being, and not just the well-being of the fossil fuel industry.”

RICHARD NELSON: Maine lobstermen know the threat posed by climate change. Now is the time to act.

December 13th, 2016 — I rose the other morning and began my preparations to head out on the water from Friendship Harbor to take up the my last load of lobster traps. My thoughts turned from from closing out my season to chuckling over my selection of boots for the day. My dear wife had made a special trip to the attic a month and a half ago to bring down my insulated winter boots, and I became aware of the fact that, with temperatures again climbing to the mid-40s, they would remain unworn this year.

Many of the thoughts and decisions fishermen make are based on conditions in the environment in which we work. This is certainly not something new. Maine’s lobster industry, which is dependent on a healthy ocean and an abundant resource of lobsters, has a long established heritage of conservation. Our good management decisions of the past include throwing back both the large breed stock lobsters and small lobsters, putting escape vents in traps and returning egg bearing female lobsters into the water, marking them to ensure they are protected through future molts. We saw the need to set trap limits and become a limited access fishery, all the while remaining a small-boat, owner-operated fleet.

Although these choices have helped create a fishery that is flourishing while others are not, we face environmental challenges that are beyond local control and more complex than our marine management system can address.

Ocean advocates hope Trump takes climate change seriously

December 9, 2016 — LONG BRANCH, N.J. — For Tom Fote, of Toms River, the decline of the lobster industry in New Jersey is proof that ocean warming is having big environmental and economic effects.

“I manage lobsters, and we saw what happened in the last 20 years. We had a huge population of lobster that grew in the Mid-Atlantic. Now it’s starting to collapse,” said Fote, who is one of three New Jersey commissioners on the Atlantic States Marine Fisheries Commission.

He told panelists at the 12th Annual Future of the Ocean Symposium, focused on priorities for the Trump administration and Congress at Monmouth University on Wednesday, that the water off New Jersey has become too warm for lobsters.

Fishermen need help dealing with the effects of climate change on their industry, he said.

Panelists at the symposium included former New Jersey Governor and federal Environmental Protection Agency Administrator Christine Todd Whitman and Donald E. Boesch, president of the University of Maryland Center for Environmental Science in Cambridge, Md.

“If I were to say one thing to the incoming administration and to the president-elect, it’s, ‘Listen to your daughter.’ Ivanka believes in climate change,” said Whitman of Donald Trump’s daughter and adviser. “It has real everyday implications to our lives, and to national safety. It is a national security issue.”

19 Ways Arctic Climate Change Could Unleash a Global Catastrophe

December 1, 2016 — Scientists have identified 19 “tipping points” that could radically change Arctic societies and environmental communities—and potentially the rest of the planet.

Those tipping points include things we’ve already heard a lot about, such as Arctic sea ice loss and the collapse of the Greenland ice sheet, as well as potential crises such as fishery collapses, a reduction of oxygen in the ocean, and the transformation of tundra ecosystems into woodlands.

“Some of these things have happened; some are more speculative,” said Garry Peterson of the Stockholm Resilience Centre, coeditor of the report, which was released last week by the center and the Stockholm Environment Institute. “Even if a bunch of these tipping points don’t happen, you’ve still got a lot to worry about.”

The biggest open question is how all these individual tipping points, also known as regime shifts, could magnify one another. “How regime shifts interact with one another is poorly understood,” Johan Rockström, executive director of the Stockholm Resilience Centre, said in a statement. “If multiple regime shifts reinforce each other, the results could be potentially catastrophic. The variety of effects that we could see means that Arctic people and policies must prepare for surprise. We also expect that some of those changes will destabilize the regional and global climate, with potentially major impacts.”

Marine Scientist Follows Hot Fish as They Move to Cooler Waters

November 30, 2016 — Warming oceans have fish on the move, and one man is in hot pursuit.

That man, Rutgers University marine biologist Malin Pinsky, has tracked fish species all over North American waters to learn where they’re headed in search of cooler conditions.

Recently, he’s seen lobsters nearly disappear from Long Island Sound, driven out by disease and a series of warm summers. The delicacies are thriving in the cooler Gulf of Maine, but that may be temporary: Water temperatures there are rising faster than anywhere else in the North Atlantic. Pinsky has also observed Black sea bass, traditionally plentiful off Virginia, start to relocate to the Gulf of Maine and the waters off the New Jersey coast. And out west, Pacific halibut and arrowtooth flounder in the eastern Bering Sea off Alaska have shifted north toward the Arctic.

“It’s not one species in one place or a few species in a limited area,” Pinsky says of the moving populations. “It’s actually hundreds of species in North America shifting toward cooler waters, and that’s significant.”

The changes pose major questions for fishermen and fishery managers. As species move, will fishermen relocate their businesses to follow? How do fishery managers set rules when fish have moved to new areas where they may be more susceptible to overfishing? And will species such as lionfish, which are invasive in the Atlantic Ocean and thrive in warm Southern waters, suddenly appear in force farther north along the Atlantic coast? Even more confounding is the effect of temperature changes on species such as corals that have difficulty relocating to a more suitable place.
