29 August 2017, VOX, Climate change did not “cause” Harvey, but it’s a huge part of the story, Nine things we can say about Harvey and climate. Several people have written some version of “what you can say about Hurricane Harvey and climate change” in the past few days. I’ll link to some of them below. But I think they are all saying too little. There’s much more to say, so much more! In fact, here are nine things you can say about Harvey and climate change. 1) Harvey is not centrally about climate change Talking about climate change during a disaster always runs the risk of insensitivity. The story that most matters about Harvey right now is the effect it’s having on lives and land in Texas and the efforts underway to prevent more suffering. More broadly, climate is never going to be central to a story like this. There have always been hurricanes and floods in Texas. The things making the state’s coastal developments vulnerable to severe weather — heedless development, sandy subsoil, insufficient drainage — would be problems even in the absence of climate change. Climate is not central, but by the same token it is grossly irresponsible to leave climate out of the story, for the simple reason that climate change is, as the US military puts it, a threat multiplier. The storms, the challenges of emergency response, the consequences of poor adaptation — they all predate climate change. But climate change will steadily make them worse. Read More here

29 August 2017, Climate Home, Hurricane Harvey: lawyers warn of climate lawsuits over damages. Hurricane Harvey is wreaking unprecedented damage on Texas. Should city planners, government agencies and businesses have seen it coming? Could they have prevented death and disruption by acting differently? Increasingly, such questions will be litigated in courtrooms and rely on climate science to answer, three environmental lawyers wrote in the journal Nature on Monday. Advances in the science of linking weather extremes to global warming has the potential to change the legal landscape, they write. The more clearly scientists can demonstrate an event was foreseeable, the more victims can – and will – seek redress from negligent authorities. “In a world where events like Hurricane Harvey are predicted to increase, and predicted confidently by scientists… courts will be called upon more and more to disentangle these issues,” co-author Sophie Marjanac, an Australian-qualified lawyer with Client Earth, told Climate Home. Marjanac give examples of potential targets for lawsuits. In Houston, Texas, developers were allowed to build on wetlands that otherwise would have helped to drain floodwaters. If it can be shown those decisions endangered people and property – and failed to anticipate known climate risks – the relevant authorities could be on the hook for payouts, she said. Read more here
28 August 2017, NewSecurityBeat, Flooding in Bangladesh: Calling Out Climate Change From the High Ground. Floods have taken the lives of more than 100 people in northern Bangladesh over the last two weeks. Fully one third of the country has been flooded and some 600,000 people have been displaced in the riverine nation as a result of monsoons in India and Nepal. At international climate forums, Bangladeshi diplomats consistently decry such disasters as part of their urgent calls for action to mitigate changing weather patterns worldwide. But here in the country’s Rangpur-Kurigam region, both authorities and citizens have been reluctant to attribute these deadly disasters to the effects of climate change. Views From the Flood Zone As part of a team of social scientists from American University (Washington, DC,) and North South University (Dhaka, Bangladesh), we have been traveling the country to find out why. Authorities, already taxed by emergency relief expenditures to help citizens recover from July’s floods, do not seem eager to acknowledge yet another crisis (especially when Bangladesh’s government and its Supreme Court are embroiled in a battle for authority). The government may also be trying to avoid drawing attention to the fact that much of the flooding has come from the opening of a dam upstream on the Teesta River in India, as the two nations currently enjoy strong bilateral relations. In addition, government officials may be hesitant to label the current crisis with an abstract, diffuse concept that is more of a long-term issue, said North South University researcher Salahuddin M. Aminuzzaman. Government officials are extremely willing to “call out” natural disasters like cyclones, monsoons, floods and drought, he said; governments can provide short-term relief for concrete, short-term problems like disasters, and, if they are organized, they can improve their stock among voters. But climate change is an amorphous, distant, and foreboding challenge. Read More here
28 August 2017, VOX, The “500-year” flood, explained: why Houston was so under prepared for Hurricane Harvey. It’s the city’s third “500-year” flood in the past three years. It’s difficult to comprehend the scale of the flooding and devastation that Hurricane Harvey and its aftermath are wreaking on the Houston area. Weather experts call the storm unprecedented, and note that it’s gone beyond even the most pessimistic forecasts. In the final reckoning, it’s certain that Harvey will be classified a 500-year flood — and maybe even a 1,000-year flood. But those terms can be a bit misleading — especially when high-profile people, like the president of the United States, confuse the issue by calling Harvey “a once in 500 year flood.” In theory, a 500-year flood is something that has a 1-in-500 shot of happening in any given year — in other words, the sort of event that’s so rare that it might not make sense to plan around the possibility of it happening. The problem is that 500-year floods are happening more often than probability predicts — especially in Houston. And, especially in Houston, prevention planning hasn’t evolved to acknowledge that a “500-year” flood isn’t really a 1-in-500 chance anymore. “500-year” floods are based not on history, but on probability. The severity of floods tends to get put in terms of years: a 100-year flood, a 500-year flood, a 1,000-year flood. But this isn’t an assessment of “the worst flood in” that time — places like Houston don’t actually have detailed weather records going back to 1017 AD, after all. Read More here
