OMG… Greenland’s ice sheets are melting fast
The Guardian UK
An urgent attempt to study the rate at which Greenland’s mighty ice sheets are melting has been launched by Nasa. The aim of the six-year project, called Oceans Melting Greenland (OMG), is to understand how fast the world’s warming seas are now eroding the edges of the island’s vast icecaps. Warming air temperatures are already causing considerable glacier loss there, but the factors involving the sea that laps the bases of its great ice masses, and which is also heating up, are less well understood.

Last week we concluded our post on climate change with a quote from James Hansen, the matter is urgent and calls for emergency cooperation among nations. All this year we have been leading up to our collective fin de seicle moment in December, the grand denouement of the Framework Convention on Climate Change and Kyoto Protocol in Paris. At this late date, we are frankly pessimistic for the outcome there.
Undamming Rivers: A Chance For New Clean Energy Source
John Waldman & Karin Limburg, Yale Environment 360
Many hydroelectric dams produce modest amounts of power yet do enormous damage to rivers and fish populations. Why not take down these aging structures, build solar farms in the drained reservoirs, and restore the natural ecology of the rivers?
The Devil in Obama’s New Emissions Target for the US Lies in Base Year Details
Vasudevan Mukunth, The Wire
The US’s carbon dioxide emissions peaked in 2005, at 5,828.63 million metric tons. This convenient choice of a base year allows the US a leeway that’s 18.64% higher than its 1990 emissions – 1990 being the year that the Kyoto Protocol uses as a base. The absence of any rules on what can or can’t constitute base years is leveraged by many countries. In Europe, for example, the base year is 1990 because that’s when emissions peaked followed by a steady decline in industrial activity as well as a growing adoption of renewable energy options.
Japan restarts first nuclear reactor since Fukushima disaster
The Guardian UK
Japan has begun a controversial return to nuclear power generation with the restart of a reactor in the country’s south-west, four and a half years after its faith in atomic energy was shattered by the triple meltdown at Fukushima Daiichi. Kyushu Electric Power, the operator of the Sendai plant, said it had restarted one of the facility’s two reactors on Tuesday morning, in defiance of strong local opposition. The move marks the first time Japan has generated nuclear power since a post-Fukushima shutdown of all its 44 operable reactors two years ago.
Space mining is closer than you think, and the prospects are great
Andrew Dempster, The Conversation
Recently, the American cosmologist Neil deGrasse Tyson gushed about the prospects of mining in space, and the benefits that might afford humanity. Is this really plausible? What can we mine in space? And will it really deliver world peace, or just another realm for competition and conflict? Perhaps a look at the immediate past and near future may help us answer some of these questions.
Sustainable development is failing but there are alternatives to capitalism
Ashish Kothari, Federico Demaria and Alberto Acosta, The Guardian UK
In the face of worsening ecological and economic crises and continuing social deprivation, the last two decades have seen two broad trends emerge among those seeking sustainability, equality and justice. First there are the green economy and sustainable development approaches that dominate the upcoming Paris climate summit and the post-2015 sustainable development goals (SDGs). To date, such measures have failed to deliver a harmonisation of economic growth, social welfare and environmental protection. Political ecology paradigms, on the other hand, call for more fundamental changes, challenging the predominance of growth-oriented development based on fossil fuels, neoliberal capitalism and related forms of so-called representative democracy.
