Arctic sea ice extent hits record low for winter maximum
The Guardian, UK
Arctic sea ice has hit a record low for its maximum extent in winter, which scientists said was a result of climate change and abnormal weather patterns. The US National Snow and Ice Data Centre (NSIDC) said on Thursday that at its peak the ice covered just over 14.5m sq km of the northern seas. This was 130,000 sq km smaller than the previous lowest maximum in 2011.
India: Machines drive 90% of power in farming, humans’ share drops to 5%
The Times of India
Silently, agriculture in India has gone through a far-reaching change in the past few decades. The share of human power available for carrying out the myriad operations in farming has shrunk to a mere 5% as has that of draught animals, the iconic oxen pulling the plough. More than 90% of the power is now drawn from mechanical sources: tractors and power tillers provide the bulk, 47%; electric motors 27% and diesel engines 16%.
Cheap Oil, Climate Change Mitigation and India
Shoibal Chakravarty, EPW
In this article, our objectives are twofold. We analyse the causes of the 2014 oil crash and its short-term impact
on the global economy. And we will complement this by considering the role that the oil crash might play in the long-term transition of the energy system that will be required to limit climate change. Finally, we discuss the outlook for India.
The Global Coal Boom Is Going Bust: Report
Mike Gaworecki, DeSmog Blog
A new report by CoalSwarm and the Sierra Club provides compelling evidence that the death knell for the global coal boom might very well have rung some time between 2010 and 2012. Based on data CoalSwarm compiled of every coal plant proposed worldwide for the past five years as part of its Global Coal Plant Tracker initiative, the report finds that for every coal plant that came online, plans for two other plants were put on hold or scrapped altogether.
Only Less Will Do
Richard Heinberg, Post Carbon Institute
Almost nobody likes to hear about the role of scale in our global environmental crisis. That’s because if growth is our problem, then the only real solution is to shrink the economy and reduce population. Population has grown from 4.4 billion in 1980 to 7.1 billion in 2013. Per capita consumption of energy has grown from less than 70 gigajoules to nearly 80 GJ per year. And we see the results: the world’s oceans are dying; species are going extinct at a thousand times the natural rate; and the global climate is careening toward chaos as multiple self-reinforcing feedback processes (including polar melting and methane release) kick into gear.
The Global Economy’s “Impeccable Logic”
Steven Gorelick, Local Futures ISEC Blog
To suggest that conventional economic thinking lacks a moral foundation is not to say that corporate CEOs and IMF economists have no moral or ethical values: most of them probably contribute to charity, feel tender thoughts towards their children and parents, and may even be angered at certain forms of injustice. The question here is whether there’s a moral dimension to the way conventional economics regards wealth inequality.
The Science of Peak Oil
Andrew McKay, Southern Limits
Peak oilers are accused of changing the definition of what peak oil actually means, therefore the entire concept of oil production peaking is rubbish. Far from a valid criticism however, this is actually a scientific virtue. If any scientist dogmatically stuck with a rigid theory as the data repeatedly proved that theory to be incorrect then that would be cause for great concern.
Photo-feature: Climate change in the Marshall Islands and Kiribati, before and after
Rémi Chauvin, Guardian UK
In the low-lying Pacific atolls of the Marshall Islands and Kiribati rising sea levels have made every high tide a dangerous event. Regular floods wash through villages causing damage to houses, killing crops and poisoning drinking water. In December 2014, photographer Rémi Chauvin recreated a set of historical images depicting the first impacts of climate change in these countries where no one lives more than a few metres above the sea.
