21 September 2017, The Conversation, Sustainable cities? Australia’s building and planning rules stand in the way of getting there. Australia’s building and land-use policy settings fall well short of what’s needed to make meaningful progress toward creating sustainable cities. You will find environmental sustainability goals and objectives in government strategy documents. But our newly released review of building and land-use planning policies around Australia has found New South Wales is the only state without serious gaps in legislation and enforcement. Research shows a large percentage of new dwellings in Australia fail to meet even minimum building requirements when checked after construction. There is little legislation and enforcement, with the notable exception of NSW’s Building and Sustainability Index (BASIX). This means neither building codes nor state planning systems are achieving sustainability goals required for a low-carbon future for cities and buildings. Sustainable cities are among the UN Sustainable Development Goals. At present, Australia ranks 20th on progress toward these goals. So how important is the built environment to Australia’s ability to achieve these goals? In fact, it’s a significant contributor to anthropogenic climate change. The built environment accounts for around 40% of worldwide energy useand one-third of greenhouse gas emissions. In Australia, the residential sector is responsible for 12% of final energy use and 13% of emissions. Read More here

31 August 2017, Bloomberg Business Week, Harvey Wasn’t Just Bad Weather. It Was Bad City Planning. Houston exulted in sprawling, hands-off growth. That’s no way to prepare for natural catastrophes. Houston has been wet since birth. In the 1840s, the German explorer Ferdinand von Roemer described the Brazos River prairie just outside the young town as an “endless swamp” that mired the wheels of his wagons. He reported that some people who’d intended to settle in Texas turned around and left after seeing the “sad picture.” But Houston never let itself be hampered by its hydrology. It spent billions patching together a mess of dams and drainage projects as it grew and grew. It’s the fourth-biggest city in the U.S., boasting one of the world’s largest medical centers, oil refineries, a stupendous livestock show and rodeo, highbrow culture, vibrant economic growth, and speakers of 145 languages. The consolidated metropolitan statistical area surrounding Houston and extending to Galveston is larger than the state of New Jersey. Read More here also here
28 August 2017, Climate Home, Link between Hurricane Harvey and climate change is unclear. Reports the devastating storm was made worse by humanity’s carbon emissions fail to grasp climate change is not just about warming. The unprecedented amount of rainfall accompanying Hurricane Harvey immediately raised the question whether and to what extent climate change is to blame. In a warming world the vapour capacity of the atmosphere increases, and more extreme rainfall, like Texas is witnessing right now, is to be expected as a result. This leads many to conclude that climate change exacerbated the impacts of hurricane Harvey. It is very appropriate to highlight that this is the kind of event we expect to see more of in a warming world. However, to apply this argument directly and attribute (and quantify) the impacts from Harvey itself to human-induced climate change, neglects that climate change is not just about warming. In a changing climate, two effects come together: not only does the atmosphere warm up (thermodynamic effect) but the atmospheric circulation, which determine where, when, and how weather systems develop, can change as well (dynamic effect).

28 August 2017, Desmog, 12 Years After Katrina, Hurricane Harvey Pummels Gulf Coast and Its Climate Science-Denying Politicians. As the remnants of Hurricane Harvey (now a tropical storm) continue to flood Houston — just days before the 12th anniversary of Hurricane Katrina — I visited Shannon Rainey, whose house was built on top of a Superfund site in the Upper Ninth Ward of New Orleans. Rainey is worried about family members in Houston. She knows all too well how long it can take to get back what is lost in a storm. “I still live with Katrina every day,” she told me. New Orleans remains threatened by bands of rain extending from Harvey, causing many residents with fierce memories of Katrina to remain on edge. Earlier this month, the city proved it was ill-prepared for hurricane season nearly a year after Baton Rouge’s 1,000-year flood. Rain inundated New Orleans, with more than nine inches falling in only three hours, exposing that the city’s pump system could not operate at full capacity. The city is still scrambling to make the needed repairs and clean the sewer system’s catch basins, which remain clogged in many places. Read More here
