5 April 2016, The Conversation, This summer’s sea temperatures were the hottest on record for Australia: here’s why. The summer of 2015-2016 was one of the hottest on record in Australia. But it has also been hot in the waters surrounding the nation: the hottest summer on record, in fact.

5 April 2016, The Conversation, What to do when machines take our jobs? Give everyone free money for doing nothing. It was Groucho Marx who said, “While money can’t buy happiness, it certainly lets you choose your own form of misery.” Quite true, but what if there’s no money coming in from work because your job’s been taken over by a machine? Low wage earners appear to be most at risk from automation. In February 2016, the Council of Economic Advisers (an agency within the Executive Office of the US President) issued an alarming report predicting that an 80% or greater chance exists for people on basic incomes of US$20 per hour or less to be made redundant by smart machines in the foreseeable future. After them come the mid-range workers. Clearly, we need strategies to address any job losses arising though increases in automation. Theoretically, just about any job that can be described as a process could be done by a computer-controlled machine. In practice though, many employers will decide that keeping a human in a job is preferable to automating it. These are jobs that involve some degree of empathy. Imagine telling a robot doctor what ails you in response to “please state the nature of your medical emergency”. Free money for all – seriously? But what about those people whose jobs are lost to automation? What if new jobs aren’t created to replace them? What are they to do if they can’t earn a living anymore? This time it’s Karl Marx, not Groucho, who comes to mind with the idea of giving people a universal basic income (UBI). This is raised as a possible remedy to any misery caused by rising unemployment from job automation. Put simply, a UBI is a pump-priming minimum income that is unconditionally granted to all on an individual basis, without any means test or work requirement. It eliminates the poverty traps that the poor fall into when welfare payments have many conditions and are administered by large and inflexible bureaucracies. The suggestion of free money is sure to raise many peoples’ hackles. Yet, this seemingly outrageous idea is being taken seriously enough to be trialled by a growing number of governments around the world, including that of Finland, the Netherlands and Canada.

30 March 2016, Board on Atmospheric Sciences and Climate, Attribution of Extreme Weather Events in the Context of Climate Change (report). The science of extreme event attribution has advanced rapidly in recent years, giving new insight to the ways that human-caused climate change can influence the magnitude or frequency of some extreme weather events. Confidence is strongest in attributing types of extreme events that are influenced by climate change through a well-understood physical mechanism—for example, the more frequent heat waves that are closely connected to human-caused global temperature increases. Confidence is lower for other types of events, such as hurricanes, whose relationship to climate change is more complex and less understood at present. For any extreme event, the results of attribution studies hinge on how questions about the event’s causes are posed, and on the data, modeling approaches, and statistical tools chosen for the analysis.

31 March 2016, Action on HFC’s Heats Up, We’re seeing new movement toward phasing down the fastest-growing group of greenhouse gases – hydrofluorocarbons, or HFCs. These chemicals are widely used in refrigerators, air conditioners, foam products, and aerosols. And while they don’t stay in the atmosphere long, they can trap 1,000 times or more heat compared to carbon dioxide. This week, the U.S. Environmental Protection Agency (EPA) proposed new regulations demonstrating its commitment to limiting the use of HFCs domestically. It proposed changes to its significant new alternatives program (SNAP) aimed at expanding the list of acceptable alternatives that minimize impacts on global warming while also restricting the use of HFCs in sectors where alternatives are now available. EPA estimates the proposed rule could avoid up to 11 million metric tons of carbon dioxide equivalent in 2030, which is equal to the energy-related emissions from about one million homes for one year. Internationally, one sign of growing support for acting on HFCs came this month during the first visit by a U.S. president to Argentina in almost two decades. President Obama and newly elected Argentinian President Mauricio Macri explored opportunities to partner to address global challenges like climate change. They affirmed their commitment to take action this year to amend the Montreal Protocol to phase down HFCs, which are substitutes for ozone-depleting chlorofluorocarbons (CFCs) that were successfully phased out under the 1989 Montreal Protocol. The two leaders also endorsed the understandings reached at the Dubai Montreal Protocol meeting in November 2015 on financial support for developing countries to implement an HFC phasedown. A key opportunity will come next week when Montreal Protocol negotiators meet in Geneva to build on the progress made toward reaching agreement this year on an HFC phasedown amendment. Overcoming challenges The April meeting will consider a range of issues including: the availability of low global warming alternatives; guidelines for the Multilateral Fund in supporting developing country strategies for reducing HFCs; and legal aspects related to the UN Framework Convention on Climate Change. Among key questions to be addressed:  Read More here
