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

January 2016, International Institute for Sustainable Development (IISD): With the release of the Trans-Pacific Partnership Agreement (TPP) last fall, a debate has been growing over the so-called “trade” agreement among twelve Pacific Rim countries. Should governments ratify the deal? Will it expand trade in a significant way? Who will be the winners and losers? But defining winners and losers only in trade terms will miss the much broader impacts of the TPP and hide the broader basis required for assessing its real impacts. In Canada, where IISD is headquartered, Trade Minister Chrystia Freeland has initiated formal consultations on the TPP, promising it is open for full discussion. This is a welcome initiative. For IISD, this is a deal too far and its ratification should be rejected by the minister. In its place, there is a need to fundamentally re-consider the role that trade and investment agreements make to supporting inclusive and sustainable growth. This commentary summarizes IISD’s concerns with the TPP, and a follow up article will begin outlining solutions. Read More here

14 January 2016, The Guardian, Climate change disaster is biggest threat to global economy in 2016, say experts. Global warming heads top economists’ concerns for first time but large-scale forced migration seen as most likely risk to materialise. A catastrophe caused by climate change is seen as the biggest potential threat to the global economy in 2016, according to a survey of 750 experts conducted by the World Economic Forum. The annual assessment of risks conducted by the WEF before its annual meeting in Davos on 20-23 January showed that global warming had catapulted its way to the top of the list of concerns. A failure of climate change mitigation and adaptation was seen as likely to have a bigger impact than the spread of weapons of mass destruction, water crises, mass involuntary migration and a severe energy price shock – the first time in the 11 years of the Global Risks report that the environment has been in first place. The report, prepared by the WEF in collaboration with risk specialists Marsh & McLennan and Zurich Insurance Group, comes a month after the deal signed in Paris to reduce carbon emissions. The WEF said evidence was mounting that inter-connections between risks were becoming stronger. It cited links between climate change and involuntary migration or international security, noting that these often had “major and unpredictable impacts”. Espen Barth Eide, the WEF’s head of geopolitical affairs, said there was a risk of Europe fragmenting as a result of “people on the move”. Speaking at a press conference in London to launch the report, Eide said: “I am concerned about the continued support in national politics for keeping Europe together.” Read More here

1 January 2016, Truthdig, So what was the most significant event of 2015? It wasn’t a single event. Rather, it was a worsening of something that started several years before. It was the fast-increasing, huge migration of immigrants—many running for fear of their lives—making their dangerous and often fatal way by land and across the Mediterranean, the Gulf of Aden, the Red Sea and the oceans of Asia. It is the greatest forced mass movement of refugees since World War II, caused by the confluence of civil war, brutal regimes, sectarian and ethnic hatred, and climate change all coming together in a world too weak and preoccupied to deal with such powerful forces….. While war is the biggest single force behind the mass migration, there are other causes, interrelated in complex ways. The best illustration of this is climate change. An organization that has been assisting refugees since 1951, the International Organization for Migration, reported that “Climate change is expected to trigger growing population movements within and across borders, as a result of such factors as increasing intensity of extreme weather events, sea-level rise and acceleration of environmental degradation. In addition, climate change will have adverse consequences for livelihoods, public health, food security, and water availability. This in turn will impact on human mobility, likely leading to a substantial rise in the scale of migration and displacement.” According to the organization, there are no reliable estimates of climate change-induced migration but 200 million people by 2050 is “the most widely cited estimate.” Read More here
