Nearly 200 Sea Turtles Die in Cape Cod Cold Snap
The record cold snap that froze the northeast Thanksgiving weekend had deadly consequences for sea turtles still swimming in Cape Cod Bay. More than 80 frozen sea turtles were brought into the Massachusetts Audubon Society's Wellfleet Bay Wildlife Sanctuary the day after Thanksgiving, and most did not survive, ABC News reported.
A full 173 turtles have died off of the Massachusetts coast since Wednesday, Mass Audubon Director Bob Prescott told CNN. A total of 227 near-frozen turtles were brought to the sanctuary over the holiday, but only 54 recovered. In total, more than 400 turtles have washed up on Massachusetts beaches since Oct. 22, more than average for the winter stranding season, the Cape Cod Times reported.
"We are at well over 400 cold-stunned turtles (for the year)—82 today, the vast majority of them frozen solid," Wellfleet Bay Wildlife Sanctuary communications coordinator Jenette Kerr told the Cape Cod Times Thursday. "[Wednesday] we had 87, the vast majority of them alive. Drastic change in the weather overnight."
Indeed, the water in Cape Cod Bay fell from lows in the high 30s Wednesday to lows of around 19 degrees Fahrenheit Thursday, ABC News reported.
The sanctuary has posted photos of its rescue efforts on its Facebook page:
Prescott blamed climate change for the deaths.
"The Gulf of Maine prior to 2010 was too cold for sea turtles to come into," he told CNN.
California Academy of Sciences sea turtle biologist Wallace Nichols agreed.
"Sea turtles are moving further north along our coast, or south to the southern hemisphere, as waters are warming and they are expanding their ranges," Nichols told NBC. "So when we get these quick swings from warm to cooler, the turtles that haven't made it south definitely get into trouble."
Changing climate and the geography of Cape Cod Bay form an especially lethal trap.
"The problem here is that they can't get out of Cape Cod Bay in time," Prescott told NBC. "The shape of the bay just confuses them."
When sea turtles are stuck in rapidly cooling waters, they can fall victim to a potentially lethal condition called "cold stunning," as the National Oceanic and Atmospheric Administration (NOAA) explains:
"Sea turtle[s] are cold-blooded reptiles that depend on the temperature of their surroundings to maintain their body temperature. Sea turtles can normally control their body temperatures by moving between areas of water with different temperatures or basking in the sun at the water's surface or on the beach. However, when temperatures rapidly decline and sea turtles are cut off from moving to warmer waters, they can suffer from a form of hypothermia we call cold stunning."
NOAA works with partners to rescue cold stunned turtles along the Massachusetts coast. The number of turtles washing up between October and Christmas has averaged 600 in recent years.

The "cold stunned" sea turtles that washed ashore this week were tropical. The majority were Kemp's ridley turtles, the most endangered species of sea turtle in the world. Green turtles and loggerheads have also numbered among the victims, the Cape Cod Times reported.
While it's been a hard week for sea turtles and their allies, there are still some bright spots. The Wellfleet Bay Wildlife Sanctuary shared a video Sunday of a Kemp's ridley turtle showing signs of life.
A "trash tsunami" has washed ashore on the beaches of Honduras, endangering both wildlife and the local economy.

More long-finned pilot whales were found stranded today on beaches in Tasmania, Australia. About 500 whales have become stranded, including at least 380 that have died, the AP reported. It is the largest mass stranding in Australia's recorded history.

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.
Sweden is a world leader in renewable energy consumption. Swedish Institute/World Bank
Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix. And as a result of competition, this localized form of power is now the country's<a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank" rel="noopener noreferrer"> home-heating market leader.</a></p>
Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

Scaling Up<p>A recent development by E.ON in Hyllie, a district on the outskirts of Malmö, southern Sweden, <a href="https://www.eonenergy.com/blog/2019/February/sweden-smart-city" target="_blank">has scaled up the smart grid principle</a>. Energy generation comes from local wind, solar, biomass and waste sources.</p><p>Smart grids then balance the power, react to the weather, deploying extra power when it's colder or putting excess into battery storage when it's warm. The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>
