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.

RHODE ISLAND: Fisheries Face Climate Peril, Aging Fleet

November 23, 2016 — As the guest speaker at Seamen’s Church Institute’s annual meeting on Monday, Nov. 14, Newport’s David Spencer, a lobsterman and president of the Commercial Fisheries Research Foundation, reviewed the state of the commercial fishing industry in Rhode Island.

Spencer has run his 85-foot lobster boat Nathaniel Lee out of Newport’s State Pier since 1973, and graciously supplies free lobsters for Seamen’s annual Rock the Docks fundraiser.

“Back then, this was a vibrant fishing port, from south to north. It had many boats that docked here,” he said. “It was a good place to fish out of.”

Spencer said that all three Newport fish houses at that time had traps off Ocean Drive, near mooring docks that would be “awash in fish” with an almost daily, intricate choreography of dockworkers sorting and loading them all into trucks. “It was something to behold,” he recalled.

According to Spencer, present-day fleets gather quahogs, lobster, crabs, conch and a little known kind of shrimp in these waters. “It’s been a good opportunity for fishermen with smaller 20-foot boats,” with trawlers catching squid, butterfish, flounder, herring, black sea bass, and more. Improved netting allows turtles, cod, and other illegal species to escape.

Working “out front” in Rhode Island Sound waters and beyond, the lobster and crab fishery becomes one, “with an explosion of Jonah crabs, which has been a godsend for much of the fleet,” said Spencer. “There is a tremendous demand for these crabs,” which augment a depleted annual lobster catch.

Lobstermen, scientists concerned about sea level, temperature rise

November 10, 2016 — PORTSMOUTH, N.H. — Lobstermen and scientists are concerned about rising sea temperatures and sea level rise in the state’s Seacoast region.

U.S. Sen. Jeanne Shaheen, D-New Hampshire, went out on a lobster boat out of Portsmouth harbor Aug. 30 to talk to fisherman about concerns they have for the potential for temperature rise in the waters and how it could impact the state’s prized, $23 million a year fishery.

Waiting for her on the dock as she returned were officials from the Rockingham County Planning Commission to discuss a related issue: sea level rise and its impacts on the seacoast.

The two go hand in hand because they are both linked to climate change.

The largest high tide of the year, the King Tide, is expected on New Hampshire’s seacoast Nov. 15.

It will give residents a glimpse into the future, where high water could be the norm. Hopefully, there will not be a weather event late that morning which would possibly impact low-lying structures.

Scientists predict that the average high tide in New Hampshire could rise by two feet in the next 35 years and be six feet higher by the year 2100 due to climate change.

These tides could damage homes, infrastructure and the tourist economy of the state.

Both Shaheen and her Republican counterpart, U.S. Sen. Kelly Ayotte, R-New Hampshire, together worked successfully last month to fight off an effort by Sweeden to ban the import of the American lobster. The European Union rejected Sweden’s request on Oct. 14.

The oceans are suffocating: Climate change is causing low oxygen levels

November 3, 2016 — Global climate change produces many effects — warming air energizes the atmosphere and intensifies storms; warmer water expands and raises sea level; storage of more carbon dioxide in the oceans is acidifying large realms. Now it is becoming clear that another, profound result of human activities is underway: lower oxygen levels in our oceans.

The world’s oceans, coastal seas, estuaries, and many rivers and lakes are experiencing declines in dissolved oxygen. Long known as an issue associated with sewage discharges and fertilizer runoff, the problem now is exacerbated by climate change, often independent of nutrient loads, and is global in scale.

If left unchecked, this decline will result in losses of fisheries and biodiversity, poorer water quality, and knock-on effects ranging from falling tourism to reduced marine ecosystem services.

In 2015, scientists from around the world formed an IOC (Intergovernmental Oceanographic Commission)-UNESCO working group called the Global Ocean Oxygen Network or GO2NE, of which I am a member. Our goals are to raise awareness about this problem, called deoxygenation, and stimulate research and policy to understand and mitigate it.

The how and why of oxygen in water

The aquatic environment holds dissolved gases; oxygen is one of them. Add in aquatic plants, a CO2 source, nutrients and light, and the resulting photosynthesis creates biomass and oxygen. Add more nutrients, and more photosynthetic production occurs. Consumers of the plant matter also use oxygen in the process and recycle the nutrients and carbon from organic to inorganic forms. This simplified cycle describes most aquatic ecosystems.

Climate Change Projections Can Be Used To List A Species As Threatened, US Court Rules

October 25th, 2016 — In a landmark ruling Monday, a U.S. appeals court said that the National Marine Fisheries Service (NMFS) — a federal agency — had acted reasonably when it proposed to list certain populations of bearded seals in Alaska as “threatened” under the Endangered Species Act. The decision, which reverses a 2014 ruling by a lower court, could pave the way for other species being accorded protections based on their vulnerability to projected changes in climate.

“This is a huge victory for bearded seals and shows the vital importance of the Endangered Species Act in protecting species threatened by climate change,” Kristen Monsell, attorney for the Center for Biological Diversity — which had, in 2008, filed a petition to list the species as threatened, said in a statement. “This decision will give bearded seals a fighting chance while we work to reduce the greenhouse gas emissions melting their sea-ice habitat and keep dirty fossil fuels in the ground.”

The Pacific bearded seal is one of the two subspecies of bearded seals. Although it is currently listed as “Least Concern” by the International Union for Conservation of Nature, the Center for Biological Diversity and the NMFS estimate — based on data from the Intergovernmental Panel on Climate Change — that the seals’ winter sea-ice habitat in the Bering and Okhotsk seas off Alaska and Russia would decline by at least 40 percent by 2050, and that the subspecies would be endangered by 2095.
