The climate chain reaction that threatens the heart of the Pacific

November 13, 2019 — Lined up along the side of their boat, the fishermen hauled a huge, heavy net up from swelling waves. At first, a few small jellyfish emerged, then a piece of plastic. Then net, and more net. Finally, all the way at the bottom: a small thrashing mass of silvery salmon.

It was just after dawn at the height of the autumn fishing season, but something was wrong.

“When are the fish coming?” boat captain Teruhiko Miura asked himself.

The salmon catch is collapsing off Japan’s northern coast, plummeting by about 70 percent in the past 15 years. The disappearance of the fish coincides with another striking development: the loss of a unique blanket of sea ice that dips far below the Arctic to reach this shore.

The twin impacts — less ice, fewer salmon — are the products of rapid warming in the Sea of Okhotsk, wedged between Siberia and Japan. The area has warmed in some places by as much as 3 degrees Celsius since preindustrial times, making it one of the fastest-warming spots in the world, according to a Washington Post analysis of data from the nonprofit organization Berkeley Earth.

Marine Heatwave in the Pacific Shrinks from “Blob” in Size, Retreats Farther Offshore

November 11, 2019 — The following was released by NOAA Fisheries:

The vast marine heatwave that spread warm temperatures across the northeast Pacific Ocean late in the summer and fall of 2019 has declined in size and pulled back from the West Coast, possibly reducing its immediate impacts on coastal ecosystems.

It has declined to about half the size and intensity it displayed in August. However scientists caution that the heatwave designated MHW NEP19a remains two to three times the size of Alaska and still retains enormous amounts of heat in the upper layers of ocean. It remains one of the top four or five largest heatwaves on record in the North Pacific in the last 40 years.

“What we are seeing now is a smaller heatwave that is farther offshore, but there is still a very large span of the Pacific Ocean that is much warmer than usual,” said Andrew Leising, a research scientist at NOAA Fisheries’ Southwest Fisheries Science Center (SWFSC) in La Jolla, California. Leising has developed criteria to detect and gauge the size and magnitude of marine heatwaves. “The question is, where does it go from here? That’s what we’re watching now.”

The edge of the heatwave is now about 1,500 kilometers (about 930 miles) from the West Coast, but still envelops much of the Gulf of Alaska. It no longer so closely resembles the enormous earlier marine heatwave known as “the Blob” that affected much of the West Coast through 2014 and 2015, causing reverberations through the food web.

Low salmon returns to many West Coast rivers in the last few years have been linked to the Blob, which reduced the availability of food when the salmon first entered the ocean as juveniles.

Climate change and overfishing are boosting toxic mercury levels in fish

November 11, 2019 — We live in an era—the Anthropocene—where humans and societies are reshaping and changing ecosystems. Pollution, human-made climate change and overfishing have all altered marine life and ocean food webs.

Increasing  temperatures are amplifying the accumulation of neurotoxic contaminants such as organic mercury (methylmercury) in some marine life. This especially affects top predators including marine mammals such as fish-eating killer whales that strongly rely on large fish as seafood for energy.

Now the combination of  pollution, climate change and overfishing are conspiring together to further contaminate marine life and food webs. This has obvious implications for ecosystems and the ocean, but also for public health. The risk of consuming mercury-contaminated fish and seafood is growing with climate change.

Rep. Joe Cunningham: A healthy ocean in 2050? We need to act now.

November 8, 2019 — The ocean is the lifeblood of our planet. It covers three quarters of the globe, produces more than half our oxygen, supports a wide range of marine fisheries that feed the planet, and absorbs 30 percent of the carbon dioxide we emit and 90 percent of the heat caused by those emissions.

In short, the ocean plays a critical role in our lives and livelihoods. And it’s just as critical that we do everything we can to protect it.

By 2050, the global population is expected to reach 9.7 billion people. While the projections regarding the impact that this population and their actions and emissions will have on the ocean may vary, none of them are good. Without definitive action now, scientists predict that by 2050:

• World fish stocks will be driven to collapse;
• Average sea levels will rise by 30-34 centimeters, increasing coastal erosion and exacerbating storms, flooding cities and coastal communities like Charleston;
• The ocean is expected to contain more plastics than fish (by weight); and
• The world’s coral reefs will be wiped out, increasing threats to coastal communities from storm surges and a loss of fish stocks that rely on corals for survival.

Climate change reports point to eating more seafood as a way to help save the planet

November 8, 2019 — The United Nations’ Climate Action Summit in New York, which kicked off Climate Week at the end of September, may be long over, but the activities that took place around the world – and the strong messaging about the need to find solutions to save the planet from global warming – reached an unprecedented number of people this year.

The Intergovernmental Panel on Climate Change (IPCC) released a post-summit special report which outlined the major changes being observed in the earth’s oceans and frozen regions. The report concluded that the negative effects of warming oceans, melting ice, and rising sea levels already being experienced will accelerate in future decades.

Hundreds of scientists gather in Portland to address climate change in the Gulf of Maine

November 5, 2019 — Several hundred scientists, conservationists and government leaders from New England and the Canadian Maritimes are gathering in Portland to discuss the rapid ecological changes in the Gulf of Maine and how the region should respond.

The Gulf of Maine 2050 International Symposium will focus on the science of sea level rise, ocean acidification and warming ocean waters, as well as how those climate-related changes will affect the regional economy, environment and population over the next three decades.

“Preparing for 2050 is a major challenge, but it is one that we won’t face alone,” said Theresa Torrent of the Maine Department of Marine Resources Maine Coastal Program and the state’s coordinator on the international Gulf of Maine Council on the Marine Environment. “The purpose of Gulf of Maine 2050 is to activate the talents of people around the Gulf of Maine and build a safe and productive future.”

The conference – hosted by the Gulf of Maine Council, the Portland-based Gulf of Maine Research Institute and the Huntsman Marine Science Centre in St. Andrews, New Brunswick – comes at a time when New England’s waters and forests are already experiencing dramatic changes.

Global Warming Is Already Destroying New England’s Fisheries

November 5, 2019 — To wake up in the Northeastern United States—as California blazes and Japan digs itself out of typhoon damage—is to experience an uneasy gratitude for all that is not burning, battered or underwater. Seven years out from Superstorm Sandy, we know not to get cocky, but there’s a relief in being able to worry about work and more pedestrian finances instead of evacuation plans, or ordering the right kind of smoke mask. It’s a small luxury in climate-didn’t-come-for-me-today compartmentalization.

But deep down, we know better. And if the national discussion hasn’t moved to climate change in the Northeast yet, it soon will. The effects are already profound—they just happen to be underwater.

Fourth-generation fisherman Al Cottone holds no illusions of being spared climate impacts in 2019.  He captains one of the 15 fishing boats still active in the waters around Gloucester, Massachusetts. Not a decade ago, there were 50. To fish in the Gulf of Maine—the ocean inlet spanning from Cape Cod up to the southern tip of Nova Scotia—is to navigate one of the fastest-warming bodies of water on the planet. “It’s not something you see with your naked eye,” Cottone told me. “But fish are definitely reacting differently, and I’m attributing it to climate change. We’re seeing them in deeper water—they’re trying to get the right temperature at depth.”

Rising sea level, flooding risk threaten Northeast ports

October 30, 2019 — Sea surface temperatures along the Northeast U.S. Atlantic coast have risen faster than 99 percent of the world’s oceans since 2004, and the accompanying change in sea level rise is putting the region at increasing risk from tidal flooding and storms, according to a new report from climate researchers.

Released on the seventh anniversary of Hurricane Sandy’s Oct. 29, 2012 landfall, the report “New Jersey’s Rising Coastal Risk” by the Rhodium Group’s energy and climate team, with contributions from scientists at Rutgers University, the University of California at Berkeley and the University of Chicago.

Sandy hit land as an post-tropical system after shedding some hurricane characteristics ­— its sustained windspeed at landfall did not even qualify as Category 1 on the Saffir-Simpson scale of hurricane intensity — but it delivered a storm surge not seen since the great hurricane of 1821.

That surge, later estimated at 14.4 feet at Sandy Hook, N.J., inundated neighborhoods all around the New York Harbor complex, including the commercial fishing port of Belford, N.J. The port’s fleet survived the storm, but its infrastructure was heavily damaged, losing electrical and refrigeration equipment, and the Belford Seafood Cooperative’s restaurant.

The New England Aquarium Wants To Monitor Whales From Space

October 28, 2019 — The New England Aquarium and Cambridge-based engineering company Draper have some big news: They’re working on technology that will allow them to monitor whales with satellites in space.

Leaving the planet to watch whales might sound a little silly, but the ability to do it could represent a giant leap forward in our ability to protect these animals and our oceans.

“Counting whales from space is really important to providing the scientific justification for [identifying] places in the ocean that are special and need protection,” says Kelly Kryc, director of conservation policy and leadership at the New England Aquarium. She adds that if we know where the whales are, and where they’re likely to go, we can try to limit human activity like fishing, shipping and energy exploration in those places.

Currently, when scientists look for whales and other large marine animals, they almost always do so from boats or planes. But these methods are weather-dependent, costly, sometimes dangerous, “and you can only go out infrequently, so you don’t get a very good sense of what’s happening at a high resolution in both time and space,” Kyrc says. If we could watch them from space, we could do a better job tracking them over longer periods of time, she adds.

In Mexico, gains from fishery management reforms could surpass losses from climate change

October 25, 2019 — Abalone along the Pacific coast in northern Mexico have declined dramatically in the last decade because of lower oxygen levels prompted by climate change. But despite that, the Pacific Federation of Fishing Cooperatives (Fedecoop) has been able to prevent overfishing by limiting the total catch, according to Laura Rodriguez, the associate vice president of the Environmental Defense Fund’s Latin and South American Oceans Program.

It’s the type of proactive governance that Mexico and Latin America need more of as climate change grows more severe, warping ocean conditions from temperature to acidity, salinity to oxygen levels, all while altering the life histories, distribution, and productivity of marine species, according to Rodriguez.
