A study published in Nature Climate Change Monday shows that thawing permafrost in the Arctic might produce more methane than previously thought. Methane has 28 times the Global Warming Potential (GWP) of carbon dioxide, so the findings indicate scientists might have to reassess how thawing permafrost will contribute to climate change.
Top Interior Department officials recently visited the Kaktovik and Utgiagvik communities in northern Alaska to let them know that the agency will publish in the coming weeks a notice in the Federal Register of its intent to move toward an environmental impact statement on planned leasing, the Anchorage Daily News reported.
Despite the heavy snowfall in the Northeast this week, spring comes faster on average than it did 10 years ago. This is especially true the farther north you travel, according to a study by the University of California, Davis.
The study, published in Scientific Reports on March 2, found that spring arrives four days earlier for every 10 degrees north you travel, compared to its arrival time a decade ago.
The Arctic just experienced its warmest winter on record, scientists say. In the dead of winter, temperatures at the North Pole approached the melting point, the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado found.
"It's just crazy, crazy stuff," NSIDC director Mark Serreze told the Associated Press. "These heat waves—I've never seen anything like this."

The Greenland shark is one of the world's largest marine species, reaching lengths over six meters (approximately 20 feet). And yet these fish, which prefer the deep, cold waters of the Arctic and North Atlantic oceans, have largely eluded scientific study.
Their evasiveness highlights how little we know about Arctic marine ecosystems—and how much we can learn by developing and employing new technologies.
Interior Sec. Ryan Zinke is the winner of the Center for Biological Diversity's 2017 Rubber Dodo award. The statue is awarded each year to the person or group who has most aggressively sought to destroy America's natural heritage or drive endangered species extinct.
"Ryan Zinke seems to wake up every day wondering how he can tear apart America's public lands, ramp up oil and gas development and put endangered species on a fast track to extinction," said Kierán Suckling, the Center for Biological Diversity's executive director.
Over the past few days, many climate scientists took to social media to express dismay over the Arctic's unseasonably warm temperatures and its record-low sea ice. At the height of winter, the region is clocking temperatures normally seen in May.
"The northernmost permanent weather station in the world, just 440 miles from the North Pole, has warmed to 43°F today—in the middle of months-long darkness during what is normally the coldest time of the year," meteorologist Eric Holthaus tweeted Saturday.
The Svalbard Global Seed Vault in the Arctic Circle—also known as the "doomsday vault" safeguarding the world's most diverse collection of seeds—now holds 1,059,646 unique crop varieties after receiving more than 70,000 samples on Monday.
Depositors from 23 seed banks around the world braved sub-zero temperatures to deliver duplicate seeds of vital staples such as rice, wheat and maize; black-eyed pea, a major protein source in Africa and South Asia; and samples of sorghum, pearl millet and pigeon pea. Several lesser-known crops such as the Estonian onion potato and the Bambara groundnut, a drought-tolerant crop being developed in Africa, also made the journey.
