15 October 2015, Carbon Pulse, Australia reapproves gigantic Adani coal mine, Indian CO2 emissions to soar. Environment Minister Greg Hunt on Thursday reapproved the construction of Adani’s Carmichael coal mine in Queensland, Australia’s biggest ever which will see around 60 million tonnes of coal exported to India annually. Hunt first approved the mine last year, but a court annulled the approval earlier this year as the government had failed to take into account the mine’s impact on two threatened species. There has also been strong public opposition against the project amid suspicions it would damage the Great Barrier Reef. The minister said on Thursday the mine had now been “approved in accordance with national environment law subject to 36 of the strictest conditions in Australian history”. Coal from the mine will cause annual CO2 emissions of around 128 million tonnes – roughly similar to the combined GHG emissions of Norway and Sweden – although those emissions will take place in India, where the coal will be exported to. Indian owner Adani has estimated coal from the mine will create 3 billion tonnes of CO2 emissions over its 60-year lifespan. “With regard to the impacts of the emissions caused by the use of the coal from the mine, recipient nations will need to meet their obligations under the United Nations Convention on Climate Change,” Australia’s Environment Ministry said.

15 October 2015, The Conversation, Death of a landscape: why have thousands of trees dropped dead in New South Wales? Trees die – that’s a fact of life. But is the death of an entire iconic landscape of Eucalyptus in the Cooma-Monaro region of New South Wales natural? For over a decade, large stands of Eucalyptus viminalis, commonly known as Ribbon Gum or Manna Gum, have been gradually declining in health, and now stand like skeletons in huge tree graveyards. In our recently published survey we found the affected area to cover almost 2,000 square km, about the size of the area burnt in the devastating Ash Wednesday bushfires in Victoria or more than the area covered by the 2003 Canberra fires. Within this area, almost every Ribbon Gum is either dead or showing signs of severe stress and dieback, with thinning crowns full of dead branches. Other tree species seem to be surviving, but this smooth-barked gum with its characteristic ribbons of peeling park, once the dominant tree of the Monaro, now seems set to disappear from the landscape.

14 October 2015, Climate News Network, Antarctic ice shelf melting could double by 2050. Scientists find that the combination of global warming and powerful winds sweeping snow off the ice of Antarctica threatens to speed up sea level rise. Antarctica, the planet’s largest desert, is home to 90% of the world’s ice – enough to raise global sea levels by at least 60 metres. So what happens to its ice and snow is a matter of serious concern to all of us. One group has just predicted that, by 2050, the rate at which the ice shelves melt will double. Another reports that powerful winds are not just shifting Antarctica’s snow, but are also blowing 80 billion tonnes of it away, into the sea or the atmosphere. Both cases exemplify the challenges of climate research and the construction of projections for the future. Inland glaciers Ice shelves are already afloat: if they melt, that will make no difference to sea levels. But floating ice that is fixed to the continental shelf also serves as a brake on the flow of glaciers further inland. So without the ice shelf “doorstops”, these could start to shed ice ever faster, and accelerate sea level rise. Luke Trusel, postdoctoral scholar at the Woods Hole Oceanographic Institutionin the US, and colleagues report in Nature Geoscience that they foresee a doubling of surface melting of the ice shelves by 2050. If greenhouse gas emissions from fossil fuel combustion continue at the present rate, by 2100 the melting may surpass the levels associated with collapse of the shelves.

12 October 2015, Climate Institute, Draft Paris agreement shows many countries still pushing for <1.5°C. Earlier last week the co-chairs of the process to the Paris climate summit released the draft agreement and draft decisions for the outcomes of the meeting. Below is a diagram that outlines, in simple terms, what these would mean for countries’ pollution reduction commitments. Note that this does not include other critical elements of the Paris outcome such as how to build resilience to growing climate change impacts and how to support the world’s poorest nations participate in climate change solutions (‘climate finance’). While critical details remain to be resolved, the draft texts highlight that the contours of the Paris agreement are becoming increasingly clear. The inevitable trend to stronger action is embedded in the draft agreement with countries needing to progressively strengthen action through time. Before getting into the details of this figure, and what it means for Australia’s target, a few overall elements of the draft agreement are worth highlighting: Read More here
