6 October 2015, Renew Economy, UN draft Paris climate pact released – Australian policy under pressure. A new draft of the global climate change pact due to be signed in Paris this December has been released by the UN, calling on all nations to commit to mitigation policies that reflect their highest possible ambition, and to toughen these commitments every five years. The 20-page draft, released by the co-chairs of the UN climate negations in Bonn on Monday, increases the pressure on countries like Australia, whose low-ball emissions reduction target has been roundly criticised for lacking ambition and not having a sufficient policy framework. The Ad hoc working group on the Durban platform (ADP), the body tasked with negotiating the agreement, prepared the greatly pared-back draft – it is less than a quarter of the length of the last version – as the basis for negotiation of the draft Paris climate package. And while it leaves many key details unclear or unstated – namely when parties should reach peak emissions growth, or how quickly curbs will have to be ratcheted up – it does include a commitment to hold warming to no more than 2°C above pre-industrial levels; a target the science dictates as crucial to avoid irreversible, catastrophic climate change. The report also contain a draft of the decision that will operationalise the agreement from 2020 and a draft decision on pre-2020 ambition. This suggests each party should regularly communicate a nationally determined mitigation contribution or commitment, which should “reflect a progression beyond its previous efforts, noting that those Parties that have previously communicated economy-wide efforts should continue to do so in a manner that is progressively more ambition us and that all Parties should aim to do so over time.” Read More here
6 October 2015, The Guardian, Perth’s water worries: how one of the driest cities is fighting climate change, From locating leaky pipes with acoustic listening to reusing wastewater, Western Australia’s capital is using technology to bridge the water gap. Perth, the capital of Western Australia, is not only one of the most isolated cities in the world, it is also becoming one of the driest in Australia. Since the gold rush of the 1890s, impressive engineering schemes have transported enough water to make Perth a city of lush lawns and eye-catching flowerbeds, to the surprise of some visitors. But a drop in average annual rainfall in recent years, along with some truly dire climate change projections, have required government and business to focus on water security. Australia’s Climate Council estimates that water flow from rainfall into Perth’s dams has slumped by 80% since the 1970s, with precipitation in the south-west corner of Australia forecast to drop by up to 40% by the end of the century. Coping with climate change Last year, Perth’s dams received just 72.4bn litres of water – far less than the 300bn currently demanded by Perth’s two million-strong population. A huge desalination facility, completed in 2006, has helped make up this shortfall, but behavioural and technological change is also bridging the gap. Read More here
