22 November 2016, Renew Economy, Climate conspiracy grips Senate as Coalition attacks latte-sipping opponents of coal. The influence of president-elect Donald Trump’s attack on “elites” is taking hold in the Australian parliament, with the Coalition attacking “latte-sipping” opponents of coal mining and joining enthusiastically in a debate questioning climate science in the Senate. Frydenberg was asked in question time by Greens MP Adam Bandt about a US government report delivered in at the Marrakech climate talks that warned, amongst other things, of a 1.5m rise in sea levels by 2050 if greenhouse emissions continued at current levels. Frydenberg responded by claiming that Australia had an “ambitious” climate target for 2030 and had been praised “for innovation” and its work on carbon capture and storage at the recent climate talks in Marrakech. A few hours later, Canada announced it would phase out traditional coal fired generation by 2030 as part of its “vision for a clean growth economy”. The UK is phasing out coal by 2023, and France is phasing out coal too, although it has taken a rain check on that idea because one third of its nuclear fleet are sidelined by safety concerns.“It it is okay for the member for Melbourne to put his sandals up on the seat, sip his soy latte, sit in the streets of Brunswick and say that it is the end of coal,” but coal would continue to be part of the mix for decades to come, Frydenberg said.

20 November 2016, New York Times, A Wrenching Choice for Alaska Towns in the Path of Climate Change. SHAKTOOLIK, Alaska — In the dream, a storm came and Betsy Bekoalok watched the river rise on one side of the village and the ocean on the other, the water swallowing up the brightly colored houses, the fishing boats and the four-wheelers, the school and the clinic. She dived into the floodwaters, frantically searching for her son. Bodies drifted past her in the half-darkness. When she finally found the boy, he, too, was lifeless. “I picked him up and brought him back from the ocean’s bottom,” Ms. Bekoalok remembered. The Inupiat people who for centuries have hunted and fished on Alaska’s western coast believe that some dreams are portents of things to come. But here in Shaktoolik, one need not be a prophet to predict flooding, especially during the fall storms. Laid out on a narrow spit of sand between the Tagoomenik River and the Bering Sea, the village of 250 or so people is facing an imminent threat from increased flooding and erosion, signs of a changing climate. With its proximity to the Arctic, Alaska is warming about twice as fast as the rest of the United States and the state is heading for the warmest year on record. The government has identified at least 31 Alaskan towns and cities at imminent risk of destruction, with Shaktoolik ranking among the top four. Some villages, climate change experts predict, will be uninhabitable by 2050, their residents joining a flow of climate refugees around the globe, in Bolivia, China, Niger and other countries.

15 November 2016, Climate News Network, Record losses as global warming worsens. While governments continue to negotiate on climate change, meteorological scientists warn that the global warming situation is rapidly deteriorating. As summers get hotter, seas get warmer and extreme wind and rainstorms inflict ever-greater loss of human life and property, the World Meteorological Organisation (WMO) is trying to develop and early warning system for vulnerable countries and regions. In a report yesterday to governments at the UN’s COP22 climate talks in Marrakesh, Morocco, the WMO said that 2016 was almost certain to be the warmest year on record, and detailed the “considerable socio-economic losses in all regions of the world” that has resulted. The deadliest event so far in 2016 has been Hurricane Matthew, which was Haiti’s worst humanitarian disaster since the 2010 earthquake, killing 546 people and injuring 438. Petteri Taalas, the WMO secretary-general, said: “Another year, another record. The high temperatures we saw in 2015 are set to be beaten in 2016. Continued global warming “The extra heat from the powerful El Niño event has disappeared, but the heat from global warming will continue.” “In parts of Arctic Russia, temperatures were 6°C to 7°C above the long-term average. Many other Arctic and sub-Arctic regions in Russia, Alaska and northwest Canada were at least 3°C above average. We are used to measuring temperature records in fractions of a degree, and so this is different. “Because of climate change, the occurrence and impact of extreme events has risen. ‘Once in a generation’ heatwaves and flooding are becoming more regular. Sea level rise has increased exposure to storm surges associated with tropical cyclones.” Read More here

11 November 2016, The Conversation, Firestorms: the bushfire/thunderstorm hybrids we urgently need to understand. Fire has been a driving force across Australia for millennia. Indeed, the health of many of our ecosystems is intrinsically dependent on fire. But bushfires are also one of our most frequent natural hazards, with a total cost estimated at A$340 million per year. In the past decade or so, extreme bushfires in southeastern Australia have burned more than a million hectares, claiming more than 200 lives and over 4,000 homes. Similar losses in other major urban areas have prompted questions about whether we are seeing a shift towards a significantly more hazardous fire regime, characterised by increasing fire frequency and intensity, and the development of catastrophic “firestorms”. While these extreme bushfires account for only a very small percentage of fire events, they are responsible for the lion’s share of bushfire-related losses. In contrast to typical bushfires, which spread across the landscape as well-defined burning fronts with smoke plumes perhaps a few kilometres high, extreme bushfires exhibit deep and widespread flaming and produce smoke plumes that can extend 10-15km into the atmosphere. At these altitudes, bushfire plumes can actually develop into thunderstorms (hence the term “firestorm”). As such, extreme bushfires become much more difficult for emergency services to handle, making them all but impossible to suppress and their spread difficult to predict. Read More here
