11 February 2016, Renew Economy, Victorian climate review calls for 1.5°C long-term emissions target. An independent review into the Victoria’s Climate Change Act has found the current legislation to be “inadequate” in its response to the threat of global warming, and has made 33 recommendations on how it can be strengthened. The most striking recommendation for the state that hosts Australia’s fleet of highly polluting brown coal-fired power generators is the introduction of a long-term state emissions reduction target based on restricting global warming to 1.5°C, as well as five-yearly interim targets. The proposed target is in keeping with the landmark pact made at the Paris COP21 to keep global temperature increase “well below” 2°C and to pursue efforts to limit it to 1.5°C. It is also in line with the current climate science, that argues 2°C could be “inadequate” as a safe limit. But the target could prove ambitious for a state that hosts some of the world’s dirtiest coal-fried power stations, and a fossil fuel dominated grid. Indeed, some – like Australian climate activist David Spratt – have questioned the target’s ability to be achieved in Victoria – even in the long term. He suggests that the “carbon budget” for the state is already used up for a 1.5C target. #Springst #Climate Change Act Review delusion: calls for long-term emissions target for 1.5C, but carbon budget for 1.5C already used up! Undertaken in 2015 and tabled in the Victorian parliament on Thursday, the review’s main goal, according to the government, was to “undo the damage” the previous Coalition government had done to the 2010 legislation, and to help restore Victoria as a leader in climate change action. …. Among its recommendations, the Committee proposes an increase in the powers of the state Environment Protection Authority (EPA) in regulating emissions reduction, and the development of a comprehensive climate change strategy every five years. It also recommends the state consider “the suite of options available to reduce emissions at their source;” and that the Act introduces a requirement for each lead department to develop an Adaptation and Disaster Risk Reduction Action Plan (ADDRAP).

8 February 2016, The Conversation, In a heatwave, the leafy suburbs are even more advantaged. Summer brings out the heliophobe in many of us. It’s manageable if you live in a house that stays cool when shut up tight. It helps if you’re physically capable of crossing to the shadier side of a hot street. It’s even better if you can work from home or use public transport stops that enjoy the cover of buildings or trees. We have reason to think a lot about shade these days, especially as the heatwaves roll in. At such times, shade is our friend. On top of the existing urban heat island effect, the incidence of extreme heat events is rising. These events are also lasting longer and getting hotter. Coverage for all is a wonderful ideal, and the federal government has announced plans to set “urban canopy” targets. But, in the meantime, some communities and areas need trees more urgently than others. Shade is not only a matter of public health; it is a social equity issue. In a warming city like Melbourne, some of the most socially vulnerable people are in areas that are most exposed to extreme heat. Our pilot research in Melbourne suggests that integrated social and ecological data sets should be used to develop programs that reduce socioecological vulnerability. Shade can be a life-saver More than twice as many people perished in Melbourne during the 2009 heatwave leading up to Black Saturday than died in the devastating fires on that day. Extreme heat is a slow-motion disaster. The tendency to respond to heat as an emergency rather than planning for an ongoing chronic stress can have deadly consequences, as Annie Bolitho and Fiona Miller argue in a forthcoming paper. Extreme heat events are increasing in duration and intensity, and some parts of cities are more vulnerable than others. AAP/Bureau of MeteorologySocial and geographic isolation, age, disability and existing health conditions all play a role in vulnerability to heat. Vulnerability to urban heat also has a geography: vulnerability is compounded by where people live and whether trees live there with them. Urban authorities are using vegetation to help fight extreme heat in susceptible areas. In large sprawling cities like Melbourne, local councils are working to increase canopy cover in their jurisdictions. Urban forests can mitigate the urban heat island effect and significantly lower surface and ambient air temperatures. Read More here
28 January 2016, Science Daily, Intact nature offers best defense against climate change. Worldwide responses to climate change could leave people worse off in the future according to a recent study conducted by CSIRO, Wildlife Conservation Society (WCS) and the University of Queensland. The paper, “Intact ecosystems provide the best defense against climate change,” published in Nature Climate Change, discusses how certain adaptation strategies may have a negative impact on nature which in turn will impact people in the long-term. “In response to climate change, many local communities around the world are rapidly adjusting their livelihood practices to cope with climate change, sometimes with catastrophic implications for nature,” according to CSIRO’s principal research scientist Dr. Tara Martin. The authors say that in Australia and Canada, conservation reserves are being used as drought relief to feed livestock, while forests in the Congo Basin in Africa are being cleared for agriculture in response to drought, and coral reefs are being destroyed to build sea walls from the low-lying islands in Melanesia. Dr. Martin added: “These are just few of the human responses to climate change that, if left unchallenged, may leave us worse off in the future due to their impacts on nature. Functioning and intact, forests, grasslands, wetlands and coral reefs represent our greatest protection against floods and storms.” The paper states that intact native forests have been shown to reduce the frequency and severity of floods, while coral reefs can reduce wave energy by an average of 97 per cent, providing a more cost-effective defense from storm surges than engineered structures.

14 January 2016, The Conversation, Hopes of a new urban age survive minister’s fall. The resignation of Australia’s first minister for cities and the built environment after just 99 days is a setback for federal leadership in these areas. Yet enough momentum and goodwill have been generated to keep the flag flying. The greatest hope is that an urban consciousness in national public policy will be lodged permanently. Even before state planning ministers assemble within months to hammer out the ground rules for federal engagement, the mutual understanding will be that the states are Australia’s primary urban governments. In August 1945, a conference of Commonwealth and state ministers in Canberra confirmed that arrangement. The states rejected a generous proposal for a central planning bureau to provide advice, training and information resources plus cover half the costs of employing technical experts to assist local authorities. Prime Minister Ben Chifley’s summation sealed the fate of the bold reconstruction initiative hatched by Nugget Coombs:… the matter ought to be left to the states. How cities became ‘orphans of public policy’ Regardless, the federal government has retained a periodic interest in cities, with mixed outcomes. Historically, most initiatives have been linked to Labor. Gough Whitlam’s Department of Urban and Regional Development (DURD, 1972-75) injected valuable locational and equity perspectives into policy. However, a big-spending command, control and co-ordinate mission proved problematic. Bob Hawke delivered AMCORD and Green Street as best-practice guidelines for residential development. This helped change the culture of the development industry. But the Hawke government’s main legacy, driven by Deputy Prime Minister Brian Howe, was Building Better Cities, centred on strategic housing, environmental and infrastructure projects. Read More here
