The Climate Post: Melting of Totten Glacier Could Trigger 6 Foot Sea-Level Rise 26.5.2016 Green on
A new study  published in the journal Nature is drawing attention to the effect of warming water on the world's largest ice mass, Totten Glacier in East Antarctica. Melting of the glacier, which has an ice catchment area bigger than California, could lift oceans at least two meters (6.56 feet). According to researchers who mapped the shape of the ice sheet as well as the thickness of rocks and sediments beneath it to examine the historical characteristic of erosion of Totten's advances and retreats, unabated climate change could cause the glacier to enter an irreversible and rapid retreat within the next century. "While traditional models haven't suggested this glacier can collapse, more recent models have," said study co-author Alan Aitken of the University of Western Australia. "We confirm that collapse has happened in the past, and is likely to happen again if we pass a tipping point, which would occur if we had between 3 and 6 degrees of warming above present." Aitken said that the Totten Glacier ...

Sustainable mobility: 3 steps to scaling up renewables in transport 2.5.2016 Green on
"The Week that Electric Vehicles Went Mainstream" was the headline of a recent blog posted by Tesla Motors. Just one week before, the company began taking reservations for its long-awaited consumer-priced sedan, which will begin production in 2017. The response was unprecedented. According to Tesla, they received 325,000 reservations in one week, which corresponds to about $14 billion in implied future sales - the biggest one-week launch of any product ever. Commentators were quick to point out that electric vehicles (EVs) still only represent a fraction of a percent of total vehicles on the road; only 500,000 of the 66 million cars sold worldwide in 2015 were electric. In truth, while the transition to a renewables-based electricity system is well underway, moving to a renewables-based transportation system is more challenging. The transportation sector has the lowest share of renewable energy use compared with every other sector of the economy, and shares are not expected to increase dramatically based ...

Sanders and Clinton Back Bioenergy, but Activists Say It's the Wrong Alternative 7.4.2016 Truthout - All Articles
For more original Truthout election coverage, check out our election section, "Beyond the Sound Bites: Election 2016." The number one form of "renewable" energy in the United States is bioenergy, an energy source derived from burning trees, crops, manure, trash or waste for electricity and/or heat, or converting transportation fuels. According to the Energy Information Administration, 49.6 percent of renewable energy in the US in 2014 came from bioenergy; 18 percent, from wind; and 4.4 percent, from solar photovoltaics. With 82 percent of US energy generated from fossil fuels , barring a reduction in energy consumption, policies facilitating the transition away from oil, gas and coal will likely continue to rely, in large part, on bioenergy.  Bioenergy poses risks because of its carbon emissions, contributions to air pollution and freshwater demand. Bioenergy's main selling point is that, unlike foreign oil, it's a locally sourced feedstock, which means more money stays in local economies. Industry and ...
