Planned gas pipeline alongside Indian Point nuclear plant stirs meltdown fears

The Guardian - Mon, 2016-04-04 21:00

Leak in pipeline being built by energy giant Spectra could lead to shutdown – or worse – at the New York state power station, experts say

Across a narrow swath cut by bulldozers and chainsaws through the woods of Westchester County, New York, triangular yellow flags are clotheslined between pairs of trees. The flags trace the eventual path of the gas pipeline that the energy giant Spectra is building through the area, escorted at times by police and harried by local residents worried by its proximity to a decaying nuclear power plant.

If that pipeline leaks or breaks, say experts, its contents could detonate and destroy the switchyard that sits 400ft from the gas line. Entergy, which runs the Indian Point power station, said the plant could be quickly shut down in such an event. Nuclear engineer Paul Blanch is not so sure. Blanch, who has previously consulted for Entergy and now assists an organization calling for the pipeline to be stopped, said that assertion is a best-case scenario. In the worst case, he said, the reactors could melt down. And he believes Entergy and Spectra have not fully considered that worst-case scenario.

Mild UK winter boosts sightings of smaller garden birds

The Guardian - Thu, 2016-03-31 15:01

Long-tailed tit returns to the top 10 most commonly seen garden birds for the first time in seven years, results from the RSPB’s Big Garden Birdwatch show

A mild winter has boosted the number of small birds visiting UK gardens, with the long-tailed tit returning to the top 10 most commonly seen species for the first time in seven years, according to results from the world’s largest garden wildlife survey.

Recorded sightings of the tiny, sociable tit rose by 44% on 2015 figures and the species was seen in more than a quarter of participants’ gardens. Other small garden bird species that are thought to have benefitted from the warmer weather include the great tit and coal tit.

Arctic sea ice extent breaks record low for winter

The Guardian - Tue, 2016-03-29 06:13

With the ice cover down to 14.52m sq km, scientists now believe the Arctic is locked onto a course of continually shrinking sea ice

A record expanse of Arctic sea never froze over this winter and remained open water as a season of freakishly high temperatures produced deep – and likely irreversible – changes on the far north.

Scientists at the National Snow and Ice Data Centre said on Monday that the sea ice cover attained an average maximum extent of 14.52m sq km (5.607m sq miles) on 24 March, the lowest winter maximum since records began in 1979.

Bison to return to Montana after 140 years in the Canadian wilderness

The Guardian - Mon, 2016-03-28 14:43

Herd ‘coming home’ under treaty between North American tribes that seeks to return bison from Canada to Montana

Descendants of a bison herd captured and sent to Canada more than a century ago will be relocated to a Montana Native American reservation next month, in what tribal leaders bill as a homecoming for a species emblematic of their traditions.

The shipment of animals from Alberta’s Elk Island national park to the Blackfeet reservation follows a 2014 treaty among tribes in the US and Canada. That agreement aims to restore bison to areas of the Rocky Mountains and Great Plains where millions once roamed.

Too good to be true? The Ocean Cleanup Project faces feasibility questions

The Guardian - Sat, 2016-03-26 22:00

While the 21-year-old founder of the Ocean Cleanup Project has succeeded in raising over $2m for a device that would extract plastic from the ocean, critics say the high-cost initiative is misdirected

Last year, nonprofit foundation The Ocean Cleanup hit a milestone en route to its goal of deploying a large, floating structure to pull plastic from the Great Pacific Garbage Patch. The organization issued a press release announcing it had completed a reconnaissance expedition that would pave the way for a June 2016 test of its prototype. With the help of $2.2m in crowdfunding, 21-year-old founder Boyan Slat announced his plans to deploy 100 kilometers of passive floating barriers in an effort to clean up 42% of the Great Pacific Garbage Patch’s plastic pollution in 10 years.

Despite considerable online enthusiasm for the project, oceanographers and biologists are voicing less-publicized concerns. They question whether the design will work as described and survive the natural forces of the open ocean, how it will affect sea life, and whether this is actually the best way to tackle the problem of ocean plastic – or merely a distraction from the bigger problem of pollution prevention. Many have also expressed concern about the lack of an environmental impact statement prior to such a large push for funding.

Three-quarters of UK children spend less time outdoors than prison inmates – survey

The Guardian - Fri, 2016-03-25 17:00

Time spent playing in parks, woods and fields has shrunk dramatically due to lack of green spaces, digital technology and parents’ fears

Three-quarters of UK children spend less time outside than prison inmates, according to a new survey revealing the extent to which time playing in parks, wood and fields has shrunk. A fifth of the children did not play outside at all on an average day, the poll found.

Experts warn that active play is essential to the health and development of children, but that parents’ fears, lack of green spaces and the lure of digital technology is leading youngsters to lead enclosed lives.

The Rockefeller Family Fund, a charity set up in 1967 by descendants of John D Rockefeller, said on Wednesday that it would divest from all fossil fuel holdings “as quickly as possible”.
