11 January 2018, ABC News – Science: Forget Paris: Australia needs to stop pretending we’re tackling climate change. As the Bureau of Meteorology confirms another record-breaking year for temperatures in Australia, we should expect a sense of urgency to be creeping into Australia’s climate policy. Instead, we’re seeing the opposite. While 2015-17 were all within the hottest six years on record, our carbon emissions also continued to increase during the same period, including an all-time peak in 2017, when unreliable land-use data was excluded from the analysis. This is despite signing up to the Paris Agreement in 2015, which outlined a plan to reduce our carbon emissions by 26-28 per cent by 2030. Government data pushed out under the cloak of Christmas indicates that we will be about 140 million tonnes — or about 30 per cent — above that target based on current growth Government optimism at odds with UN: Despite last financial year’s continued emissions growth, Environment and Energy Minister Josh Frydenberg remains upbeat about Australia’s commitment to the Paris Agreement. “If you look on a yearly basis that is true [that emissions went up]. But if you look on the last quarter, they went down. If you look at the trend, it is improving. And when you talk about the 2030 target, which is our Paris commitment, the numbers that were most recently shown, indicate that they were 30 per cent better than when Labor were last in office,” the Minister told RN Breakfast. But his optimism is at odds with a number of experts, and is contrary to what was reported in the United Nations Emissions Gap Report (see below), 2017. “Government projections indicate that emissions are expected to reach 592 [million tonnes] in 2030, in contrast to the targeted range of 429-440 [million tonnes],” the report states..

11 January 2018, Yale Climate Connections, Bomb-cyclone’ weather in a warming world. This month’s Yale Climate Connections ‘This is not Cool’ video offers a plain-English science-based response to the inevitable ‘So much for climate change’ weather riddle. With New England, much of the middle Atlantic region, and parts of the southeast extending well into Florida suffering through late December-, early January-punishing cold temperatures, and in a number of places, record night-time lows and heavy snowfalls – the inevitable “so much for global warming” argument seemed certain to arise. On the one hand there were analytical news stories such as The Washington Post’s Capital Weather Gang’s story headlined “Historic ‘bomb cyclone’ unleashes blizzard conditions from coastal Virginia to New England. Frigid air to follow.” There also was President Trump’s “we could use a little more of that good old global warming” tweet from his “balmy Mar a Lago” residence looking forward to a frigidly cold New Years Eve dropping of the 2018 ball at Times Square in New York City. So how then to explain such not-at-all-unusual experience of cold weather temperatures even as the global temperatures continue rising? (One can safely anticipate having to explain cool summer-time daily temperatures in some places as the world continues warming.) To some extent, it’s a simple question of needing to repeatedly explain the difference between weather (short term and local) and climate (long term and global). Read More here
11 January 2018, The Conversation, Explainer: ‘bomb cyclones’ – the intense winter storms that hit the US (and Australia too). The eastern United States experienced a very severe winter storm last week, which caused damaging winds, heavy snow and the highest tide on record for Boston. Meteorologists call this type of storm a “bomb cyclone”, or simply a “bomb”. But what is it? A “bomb” is an old meteorological term for a low-pressure system outside the tropics (that is, an extratropical cyclone) that intensifies very rapidly, based on how fast the atmospheric pressure drops at the centre of the storm. A common benchmark is a drop of 24 hectopascals (hPa) over 24 hours, although this varies slightly with latitude. The recent bomb in the US had a reported pressure drop of 59hPa over 24 hours, making it one of the strongest such storms ever recorded. Read More here
11 January 2018, Arctic cause of loopier cold weather? A QUICK SUMMARY: The Science Linking Arctic Warming to This Crazy-Cold Winter: It’s well known that the rapidly warming Arctic is melting sea ice, thawing permafrost, and accelerating sea-level rise. But a growing body of research suggests, counter intuitively, that it could also be amplifying cold snaps, much like the brutal one now freezing the East Coast. ANOTHER VIEW: US cold snap was a freak of nature, quick analysis finds. The cold snap that gripped the East Coast and Midwest region was a rarity that bucks the warming trend, said researcher Claudia Tebaldi of the National Center for Atmospheric Research and the private organization Climate Central.
