26 July 2015, DeSmog, Senators Call For End To Arctic Drilling As Shell Gets Permits To Begin Work In Chukchi Sea: Shell received the final permits it needed to begin drilling exploratory wells in the Chukchi Sea last Wednesday, but a group of Senators led by Oregon’s Jeff Merkley is calling for a ban on Arctic drilling altogether. According to the Associated Press, the permits are somewhat conditional: In granting the company the green light, the Department of the Interior said Shell can only drill the top sections of wells, or to about a depth of 1,300 feet, because critical emergency response gear, including a well-capping device in the event of a blowout or leak, will not be present for the foreseeable future. The capping stack and other emergency gear is on board the MSV Fennica, which is in Portland, Oregon for repairs after Shell opted to send the ship out of Dutch Harbor, Alaska on July 3 via a shallow and evidently treacherous route, choosing speed over safety. The Fennica is an icebreaker — a ship literally designed to break through ice, one of two such ships in Shell’s Arctic fleet meant to protect its drill rigs from unsafe ice conditions. But the Fennica somehow suffered a gash in its hull more than 3 feet long before even leaving the harbor and was forced to head immediately back to port. There is no word on how long the repairs will take. When the capping stack is available to be deployed within 24 hours, aDOI spokesperson told the Associated Press, Shell can apply for an amended permit that would allow the company to drill deeper. That is cold comfort to critics of Shell’s Arctic drilling plans, who have repeatedly pointed out that the remote Arctic waters of the Chukchi Sea, where the company plans to drill, will make cleanup of any spill extremely difficult even if Shell has all of its emergency gear on hand. An oil spill would be devastating, environmentalists argue, but any drilling activities are likely to be incredibly disruptive in the fragile Arctic ecosystem. Read More here

21 July 2015, The Conversation, The march of the king crabs: a warning from Antarctica: Changing wildlife: this article is part of a series looking at how key species such as bees, insects and fish respond to environmental change, and what this means for the rest of the planet. Hundreds of metres below the surface of the freezing ocean surrounding Antarctica, the seafloor is teeming with life. The animals living there have no idea that an army is on the brink of invading their tranquil environment. The army is composed of king crabs. Until 2003, there were no crabs in this fragile Antarctic ecosystem. Now, driven by warming waters, their arrival heralds a major upset. The unique communities living on the continental shelf off Antarctica are found in no other place on Earth. Delicate brittle stars, beautiful sea stars, vibrant sea lilies, and giant sea spiders are among the spectacular inhabitants found there. The animals live side by side, with almost no predators to upset the balance. For millions of years, the cold water temperatures in the Antarctic have stopped most predators from surviving in this harsh environment. But this situation is rapidly changing. Read More here
20 July 2015, Science Daily, Changing climate lengthens forest fire season: Over a 35-year period, the length of forest fire seasons worldwide increased by 18.7 percent due to more rain-free days and hotter temperatures, according to research. The study examined weather data from 1979 through 2013 to determine how a changing climate impacts forest ecosystems. Over a 35-year period, the length of forest fire seasons worldwide increased by 18.7 percent due to more rain-free days and hotter temperatures, according to South Dakota State University professor Mark Cochrane, a senior scientist at the Geospatial Sciences Center of Excellence. The wildfire expert is part of a team of researchers led by W. Matt Jolly of the U.S. Forest Service Fire Science Laboratory that examined weather data from 1979 through 2013 to determine how a changing climate impacts forest ecosystems. “For things to burn, they have to have the proper conditions,” he explained. Four independent environmental factors increase the likelihood of wildfires — hotter temperatures, decreased relative humidity, more rain-free days and higher wind speeds. The researchers combined fire danger indexes from the United States, Canada and Australia with three global climate databases to create what Cochrane calls “an ensemble model.” They looked at the length of time and areas where conditions were conducive to fires. Their findings are published in Nature Communications. “Ecosystems are designed to withstand the normal climate situation, but we suspect that things aren’t normal anymore,” Cochrane said. On all the forested continents, except Australia, the fire seasons are getting longer, Cochrane explained. South America had the largest increase — 33 days in 35 years. In addition, the area affected by the longer fire season has doubled. Read More here
20 July 2015, WRI, An opportunity not to be wasted: The waste sector permeates almost every aspect of our society, and its mismanagement can lead to serious problems. Worldwide, we generated 1.3 billion tons of waste in 2012, which accounted forabout 5 percent of global greenhouse gas emissions. This volume is project to rise to 2.2 billion tons by 2025, with most of the increase expected in cities in the so-called emerging economies like Brazil, China, India, Mexico, and South Africa. The waste management utility sector is in the eye of the storm, and its evolution will be crucial to humanity’s response to various environmental challenges. As discussed in my previous blog in this series, the utility ecosystem is unable to respond to our social and environmental challenges because of entrenched interests, archaic infrastructure, systemic rigidities, and corporate inertia—all of which are painfully evident in the solid waste sector.
