How to defuse the methane timebomb in the Arctic? Unleash the mammoths!

When Rebecca Burgess was working in villages across Asia, she saw the impacts of the clothing industry firsthand: waste, pollution, widespread health problems. But in these same communities, from Indonesia to Thailand, Burgess also saw working models of local textile production systems that didn’t harm anyone. She was inspired to build a sustainable clothing system — complete with natural dye farms, renewable energy-powered mills, and compostable clothes — back home in the United States.

The result is Fibershed, a movement to build networks of farmers, ranchers, designers, ecologists, sewers, dyers, and spinners in 54 communities around the world, mostly in North America. They are ex-coal miners growing hemp in Appalachia and workers in California’s first wool mill. In five years, Burgess plans to build complete soil-to-soil fiber systems in north-central California, south-central Colorado, and eastern Kentucky.

People have asked her, “This has already left to go overseas — you’re bringing it back? Are you sure?” She is. Mills provide solid, well-paying jobs for people “who can walk in off the street and be trained in six months,” Burgess says. “This is all about dressing human beings at the end of the day, in the most ethical way that we can, while providing jobs for our home communities and keeping farmers and ranchers on the land.”

It’s only June, and Arctic sea ice already hit a new low

It’s only June, and Arctic sea ice already hit a new low

The summer sea-ice cover over the Arctic raced towards oblivion in June, crashing through previous records to reach a new all-time low.

The Arctic sea-ice extent was a staggering 260,000 square kilometers (100,000 square miles) below the previous record for June, set in 2010. And it was 1.36 million square kilometers (525,000 square miles) below the 1981-2010 long-term average, according to the National Snow and Ice Data Center.

That means a vast expanse of ice — an area about twice the size of Texas — has vanished over the past 30 years, and the rate of that retreat has accelerated.

Aside from March, each month in 2016 has set a grim new low for sea-ice cover, after a record warm winter.

January and February obliterated global temperature records, setting up conditions for the further retreat of the Arctic summer ice cover, scientists have warned.

Researchers did not go so far as to predict a new low for the entire 2016 season. But they said the ice pack over the Beaufort Sea was studded with newer, thinner ice, which is more vulnerable to melting. Ice cover along the Alaska coast was very thin, less than 0.5 meters (1.6 feet).

The loss of the reflective white ice cover in the polar regions exposes more of the absorptive dark ocean to solar heat, causing the water to warm up. This goes on to raise air temperatures, and melt more ice — reinforcing the warming trend.

Scientists have warned the extra heat is the equivalent of 20 years of carbon emissions.

From mid-June onwards, ice cover disappeared at an average rate of 74,000 square kilometers (29,000 square miles) a day, about 70 percent faster than the typical rate of ice loss, the NSIDC said.

Sea ice loss in the first half of the month proceeded at a lower pace, only 37,000 square kilometers (14,000 square miles) a day.

The overall Arctic sea-ice cover during June averaged 10.60 million square kilometers (4.09 million square miles), the lowest in the satellite record for the month, according to the NSIDC.

There was more open water than average in the Kara and Barents seas as well as in the Beaufort Sea, despite below average temperatures, the NSIDC said.
