31 October 2016, The Conversation, Turnbull wants to change Australia’s environment act – here’s what we stand to lose. Prime Minister Malcolm Turnbull is seeking changes to Australia’s national environment act to stop conservation groups from challenging ministerial decisions on major resource developments and other matters of environmental importance. Turnbull is reviving a bid made by former Prime Minister Tony Abbott to abolish Section 487 of the Environment Protection and Biodiversity Conservation Act (EPBC Act) – a bid rejected in the Senate in 2015. If it goes ahead, the change will significantly diminish the functionality of the act. The EPBC Act, introduced by the Howard government in 1999, has an established record of success. Judicial oversight of ministerial discretion, enabled by expanded standing under Section 487, has been crucial to its success. Section 487 allows individuals and groups to challenge ministerial decisions on resources, developments and other issues under the EPBC Act. An organisation can establish standing by showing they have engaged in activities for the “protection or conservation of, or research into, the environment” within the previous two years. They must also show that their purpose is environmental protection. Repealing this provision would remove the standing of these groups to seek judicial review of decisions. Standing would then revert to the common law position. That means parties would need to prove they are a “person aggrieved” by showing that their interests have been impacted directly. Read More here

31 October 2016, The Conversation, Unnatural disasters: how we can spot climate’s role in specific extreme events. These days, after an extreme weather event like a cyclone, bushfire, or major storm, it’s common to find people asking: was it climate change? We also often hear people saying it is impossible to attribute any single weather event to climate change, as former prime minister Tony Abbott and the then environment minister Greg Hunt said after the bushfires in New South Wales in 2013. While this may have been true in the 1990s, the science of attributing individual extreme events to global warming has advanced significantly since then. It is now possible to link aspects of extreme events to climate change. However, as I describe in an article co-written by Susan Hassol, Simon Torok and Patrick Luganda and published today in the World Meteorologcal Organization’s Bulletin, how we communicate these findings has not kept pace with the rapidly evolving science. As a result, there is widespread confusion about the links between climate change and extreme weather. Evolving science The science of attributing individual extreme weather events to climate change dates back to 2003, when a discussion article in Nature raised the question of liability for damages from extreme events. The idea was that if you could attribute a specific event to rising greenhouse gas emissions, you could potentially hold someone to account. This was soon followed by a 2004 study of the 2003 European heatwave, which caused more than 35,000 deaths. This analysis found that climate change had more than doubled the risk of such extreme heat. Read More here
27 October 2016, Climate Home, Whiffs of sulphur: UN shipping talks face climate dilemma. Historic pact to cut sulphur emissions from shipping sector hailed by green groups, but slow progress suggests a climate deal is a long way off. Whisper it, but the shipping industry is showing signs of tackling its environmental footprint. This week at International Maritime Organisation (IMO) talks in London around 170 countries agreed to tighten limits on toxic sulphur emissions from ships. The decision means the sulphur content of maritime fuels has to be cut from a current maximum of 3.5% to 0.5% in 2020, and could prevent 200,000 premature deaths, say experts. It’s a significant step and one that the likes of WWF, Friends of the Earth and Brussels-based NGO Transport and Environment have been pushing for in the past few years. “This is a landmark decision and we are very pleased that the world has bitten the bullet and is now tackling poisonous sulphuric fuel,” said Bill Hemmings, T&E shipping director. Still, the battle to get this deal has been immense, and raises questions over the capability of the IMO to deliver a similar agreement on climate change, its next major task. The sulphur fight has lasted a decade. Only now, with the European Union pushing hard for tougher global regulations and China implementing its own standards has a pact seemed likely. Read More here
27 October 2016, Aust Antarctic Division, Impact of East Antarctic glacial melt on sea-level rise. The Australian Antarctic Program will study two glaciers, the Totten and Sørsdal, in East Antarctica this summer to better understand the impact ice melt is having on global sea-level rise. The Totten Glacier, near Australia’s Casey research station, is the largest glacier in East Antarctica, and is showing signs that it is sensitive to warm ocean waters that can increase melt at the base of the ice shelf. Australian Antarctic Division Glaciologist, Dr Ben Galton-Fenzi, said researchers want to better understand how much this glacial melt is driving sea-level rise. “Since the 1900s the global sea-level has risen by around 20 centimetres and by the end of the century it’s projected to rise by up to one metre or more, but this is subject to high uncertainty,” Dr Galton Fenzi said. “These estimates depend critically on understanding Antarctic glaciers, both how much and how fast they melt in a warming climate. This summer researchers will look at how warmer ocean water is melting glaciers and ice shelves from below. “We will land helicopters on the Totten to deploy six GPS units to measure glacial flow speeds and surface elevation changes.
