Front line of climate change: Black sea bass surge off R.I.

July 16, 2018 — Scientists tell us that some fish will be winners and others losers as oceans warm.

In Rhode Island, count lobster, silver hake and winter flounder among the losers, their numbers plummeting as climate change drives water temperatures higher. On the list of winners so far are squid, summer flounder, butterfish.

And black sea bass. The population of the dusky-colored fish with striking blue accents has historically been strongest off the mid-Atlantic Coast, but over the past decade or so its numbers have spiked off New England and it is becoming a more important catch for the region’s fishermen.

In a telling sign of black sea bass’s surge in Rhode Island, the state Department of Environmental Management last month loosened regulations governing the recreational fishery for the species, extending the season by 31 days and increasing the fall possession limit to seven fish per person per day, from five.

Shifting fish giving New Jersey an early global warming challenge

July 13, 2018 — The slow warming of the Earth someday will require difficult adaptations in many sectors of society, for example farming, energy and insurance.

One challenge already is here — fish. They are voting with their fins, moving northward out of warming ocean waters and into cooler temperatures they prefer. And that is disrupting fisheries management and quotas, which only recently had achieved stability and acceptance.

Earlier this year, a study led by a Rutgers University marine biologist predicted two-thirds of the 700 ocean species it analyzed would be forced to migrate — some more than 600 miles — in the worst warming scenarios.

A 2016 National Oceanic and Atmospheric Administration study found half of the Northeast’s fish and shellfish were highly vulnerable to climate change. It warned that fisheries dependent on a single valuable species, such as New Jersey is on scallops, are at particular risk.

And global warming might shrink fish as well. A pair of University of British Columbia scientists last year reported the size of fish is likely to decrease by 20 to 30 percent for every 1 degree Celsius increase in water temperature, as their metabolisms speed up and the oxygen content of the water diminishes.

NOAA chief backs away from comments about climate change

July 3, 2018 — The acting head of the U.S. agency that oversees the country’s oceans policy is downplaying remarks he recently made about climate change.

Last week, The Hill reported that Tim Gallaudet, the acting administrator for NOAA, gave a presentation at a conference put together by the U.S. Commerce Department where he floated a new mission statement for the agency. Gallaudet, a retired Navy rear admiral who also serves as the assistant commerce secretary for oceans and atmosphere, reports to Commerce Secretary Wilbur Ross.

Currently, NOAA’s mission statement begins with “To understand and predict changes in climate, weather, oceans, and coasts.” In his presentation, Gallaudet offered an amended mission statement that read: “to observe, understand and predict atmospheric and ocean conditions.”

The Union of Concerned Scientists released the presentation to the public. After its release, Gallaudet issued a statement saying he intended his remarks to show how NOAA could find new ways to work with in the Commerce Department’s strategic plan. He said his presentation was not to be considered as a finished product, according to The Hill.

“Secretary Ross, the Department, and I support NOAA’s mission to understand and predict changes in climate, weather, oceans and coasts; to share that knowledge and information with others; and to conserve and manage coastal and marine ecosystems and resources,” Gallaudet said. “We are also fully aware of the congressional mandates and will continue to adhere to them.”

‘Storminess’ Could Make Fishing More Risky as Climate Warms

July 2, 2018 — Tens of thousands of people die every year trying to catch fish to eat or sell, and weather is one of the biggest hazards to lives and equipment. The International Red Cross estimates that 3,000–5,000 people, mainly fishers, are killed by intense thunderstorms on Africa’s Lake Victoria each year. In 2013, Typhoon Haiyan destroyed some 30,000 fishing boats in the Philippines.

The dangers of fishing are no secret, but a warming planet could make the job even more risky. A team of researchers in England is calling for a closer look at how increasingly stormy weather will affect global fisheries.

In a study published in the journal Nature Climate Change, they warn that nastier weather in the future will make fishing more dangerous for millions of fishers and, by reducing catches, could threaten the health and well-being of billions of people who eat seafood. The biggest challenge is that few have studied this question. Although there’s been plenty of research on how ocean warming could reduce fish catch in the next 50–100 years, they said, changing “storminess” could actually be a more immediate, catastrophic issue.

“We really want to encourage more research in this area, because we think it’s really critical for the future,” said lead author Nigel Sainsbury, a scientist at the University of Exeter’s Environment and Sustainability Institute.

Already, scientists have looked at how large storms can damage coral reefs, cause fish to evacuate large areas and flood estuaries with salty ocean water. Some storm systems may also benefit fish by strengthening ocean upwelling that allows phytoplankton and zooplankton – food at the base of the marine food chain – to thrive, according to research led by United States National Marine Fisheries Service scientists.

NOAA’s Research Just Shifted from Climate Change to “Empowering the Economy” and “National Security”

June 26, 2018 — One of the country’s major federal science agencies seems to have been forced to abandon climate change research as a key organizational focus, the New York Times revealed this week. The National Oceanic and Atmospheric Organization is responsible for managing the National Weather Service and using its network of satellites to forecast the effects of climate change. Rather than concentrate on resiliency efforts, NOAA is now charged with prioritizing “a safe, secure and growing economy empowered through accurate, reliable and timely environmental information,” according to a slideshow presented by the agency’s acting director at a Department of Commerce meeting.

The Times had the details of the policy shift, the latest under President Trump’s watch:

In the presentation, which included descriptions of the past and present missions for the agency, the past mission listed three items, starting with “to understand and predict changes in climate, weather, oceans and coasts.” In contrast, for the present mission, the word “climate” was gone, and the first line was replaced with “to observe, understand and predict atmospheric and ocean conditions.”

The presentation also included a new emphasis: “To protect lives and property, empower the economy, and support homeland and national security.”

Ocean science agency chief floats removing ‘climate’ from mission statement and focusing on trade deficit

June 26, 2018 — A recent presentation by the acting head of the United States’ top weather and oceans agency suggested removing the study of “climate” from its official mission statement, focusing the agency’s work instead on economic goals and “homeland and national security.”

Critics say this would upend the mission of the $5.9 billion National Oceanic and Atmospheric Administration. But the administration disputes that interpretation, saying the presentation did not intend to create a change of direction at a vast agency that tracks hurricanes and atmospheric carbon dioxide, operates weather satellites, manages marine reserves and protects endangered ocean species, among other functions.

NOAA’s mission, the agency says, is “to understand and predict changes in climate, weather, oceans, and coasts, to share that knowledge and information with others, and to conserve and manage coastal and marine ecosystems and resources.”

But in a presentation at a Commerce Department “Vision Setting Summit” this month, Rear Adm. Timothy Gallaudet, the agency’s acting administrator, suggested a change to that mission statement, as well as a new emphasis on tripling the size of the U.S. aquaculture industry within a decade and moving to “reduce the seafood trade deficit.”

The new NOAA mission, the presentation said, would be “to observe, understand and predict atmospheric and ocean conditions, to share that knowledge and information with others, and to protect lives and property, empower the economy, and support homeland and national security.”

“This presentation is a simplified draft for discussion,” said Gallaudet, an oceanographer who has spoken in the past about climate change’s effects on the Arctic, in a statement provided by the agency. “It was not intended to create change in NOAA mission or policy from what it was before. Any interpretation to the contrary is simply inaccurate.”

But the proposed removal of language about studying the “climate” and about the managing of coastal and marine resources has aroused considerable ire and concern.

Fish wars loom as climate change pushes lobster, cod, and other species north

June 22, 2018 — Over the past 50 years, as Atlantic waters have warmed, fish populations have headed north in search of colder temperatures. Lobsters have migrated 170 miles and the iconic cod about 65 miles, while mid-Atlantic species such as black sea bass have surged about 250 miles north, federal surveys show.

But fishing limits and other rules, by and large, haven’t shifted with them.

The rapid movement of fisheries, in New England and around the world, has outpaced regulations and exacerbated tensions between fishermen in competing regions and countries, threatening to spark conflicts that specialists fear could lead to overfishing.

“This is a global problem that’s going to be getting worse,” said Malin Pinsky, an assistant professor of ecology at Rutgers University, who led a recently released study on the movement of fisheries in the journal Science.

With climate change expected to accelerate in the coming years, new fisheries are likely to emerge in the waters of more than 70 countries and in many new regions, the study found.

Fishing quotas in the United States have been traditionally set by councils overseeing specific regions, based on the belief that fish don’t move much.

Climate Change Brought a Lobster Boom. Now It Could Cause a Bust.

June 21, 2018 — At 3:30 in the morning on a Friday in late May, the lobstermen ate breakfast. Outside, their boats bobbed in the labradorite water, lit only by the dull yellow of streetlamps across the bay. It was windy, too windy for fishing, but one by one the island’s fishermen showed up at the Surfside cafe anyway. Over pancakes and eggs, they grumbled about the season’s catch to date.

Some of the lobstermen said it was just too early in the season. Others feared that it was a sign of things to come. Since the early 1980s, climate change had warmed the Gulf of Maine’s cool waters to the ideal temperature for lobsters, which has helped grow Maine’s fishery fivefold to a half-billion-dollar industry, among the most valuable in the United States. But last year the state’s lobster landings dropped by 22 million pounds, to 111 million.

Now, scientists and some fishermen are worried that the waters might eventually warm too much for the lobsters, and are asking how much longer the boom can last.

“Climate change really helped us for the last 20 years,” said Dave Cousens, who stepped down as president of the Maine Lobstermen’s Association in March. But, he added, “Climate change is going to kill us, in probably the next 30.”

Climate change moving fish north, threatening turf wars, study says

June 21, 2018 — World conflict is likely to increase over access to fisheries, as species move north in response to a warming ocean, according to a Rutgers University study published last week in the journal Science.

“Seventy or more countries will likely have to start sharing with their neighbors” in coming decades, said lead author Malin Pinsky, including the U.S., Canada and Mexico.

The danger comes from overfishing when countries can’t cooperate, he said. Consumers and economies are harmed by overexploitation.

“If there’s a fish fight, you end up with less fish for everyone — less fish on every plate, fewer jobs for local economies and less profit for local businesses,” said Pinsky, 37, an assistant professor in Rutgers’ Department of Ecology, Evolution and Natural Resources who is soon to be an associate professor.

The right to harvest particular species of fish is usually decided by national and regional fishery management bodies, which assume species don’t move much, Pinsky said.

“Well, they’re moving now because climate change is warming ocean temperatures,” he said. Studies have estimated the oceans have absorbed about 93 percent of recent increases in global temperatures.

Climatic conflict: Is the Mackerel War a model for future trade disputes?

June 20, 2018 — What happens when a fish crosses the border? A new Rutgers University study presents evidence that as fish move with changing water temperatures, their tendency to cross borders will cause political conflicts among nations with varying fishery management authorities.

Fishery regulators write rules “based on the notion that particular fish species live in particular waters and don’t move much,” says Malin Pinsky, assistant professor of ecology, evolution and natural resources in Rutgers–New Brunswick’s School of Environmental and Biological Sciences. “Well, they’re moving now because climate change is warming ocean temperatures.”

“Consider flounder, which have already shifted their range 250 miles farther north,” Pinsky says. “Federal fisheries rules have allocated many of those fish to fishers in North Carolina, and now they have to steam hundreds of extra miles to catch their flounder.”

Because fish are typically more nimble than their management systems, this kind of movement will exacerbate international fisheries conflicts, Pinsky says.

“Avoiding fisheries conflicts and overfishing ultimately provides more fish, more food and more jobs for everyone,” says Pinsky. He and his co-authors cite the “mackerel war” between Iceland and the European Union as an example of the disruption of fisheries causing international disputes.
