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
9 August 2017 By Dr Haydn Washington for Dick Smith Fair Go,The Insanity of Endless Growth, . The world is faced with a predicament of grave enormity – yet one rarely spoken of. The United Nations (UN), almost all governments, business, and media and both the political Left and the Right are busy extolling (even praising) ‘endless growth’. Yet we live on a finite planet, so clearly endless physical growth is impossible, unsustainable and, in fact, insane. I often give public talks on sustainability and ask the audience: ‘On a finite planet who thinks we can keep growing physically forever?’ Nobody raises their hands. So why then is our economy and society based on what many individually know is impossible? An excellent question – but one hardly ever asked in mainstream economics (Daly, 2014). Even the UN forgets to ask the question – and to answer it. Read More here
12 July 2017, The Guardian, Commentators who don’t understand the grid should butt out of the battery debate. Criticising South Australia’s battery for not meeting peak demand is akin to raging at your smartphone because it can’t send a fax. he Australian electricity grid’s most recently announced extremity is a gargantuan battery system in South Australia, designed to bolster grid security. The facility has been met mostly with a warm welcome, interspersed with weird, interesting and tense hostility. Buried in the mix of reactions are clues about how a new phase of grid transition might play out, as we switch from the rapid build out of zero carbon power sources to building and integrating them into a system designed for fossil fuels.Before we interrogate the misunderstandings of South Australia’s new battery, we have to step back and look at the system as a single, electric organism.
