25 January 2016, New Scientist, US east coast snowstorms linked to slowdown of Atlantic current. The record snowfall that paralysed much of the east coast of the US on the weekend could be partly due to a slowing of the Atlantic currents that transport heat northwards towards Greenland and Europe. Winter storms like Jonas, as some are calling it, are caused when cold air from Canada collides with warm, moist air flowing up from the tropical Atlantic. Because the waters off the east coast are much warmer than normal for this time of year, the winds blowing onshore carried more moisture than usual, which is why the snowfalls were so high – breaking records in several places. New York’s JFK airport recorded 77 centimetres on 23 January, for instance, the most ever recorded on a single day. Nearly 30 deaths have been blamed on the storm, from car accidents to heart attacks while shovelling snow. Flooding risk The remnants of Jonas are now heading across the Atlantic to the UK, where it is feared they will cause yet more flooding. Global warming is the obvious explanation for the unusual warmth, and computer models are likely to show that storm Jonas was made much more likely because of climate change.The El Niño that helped push global temperatures to record-smashing levels last year may also have played a part. But there may be more to it. Read More here
14 January 2016, The Guardian, Climate change disaster is biggest threat to global economy in 2016, say experts. Global warming heads top economists’ concerns for first time but large-scale forced migration seen as most likely risk to materialise. A catastrophe caused by climate change is seen as the biggest potential threat to the global economy in 2016, according to a survey of 750 experts conducted by the World Economic Forum. The annual assessment of risks conducted by the WEF before its annual meeting in Davos on 20-23 January showed that global warming had catapulted its way to the top of the list of concerns. A failure of climate change mitigation and adaptation was seen as likely to have a bigger impact than the spread of weapons of mass destruction, water crises, mass involuntary migration and a severe energy price shock – the first time in the 11 years of the Global Risks report that the environment has been in first place. The report, prepared by the WEF in collaboration with risk specialists Marsh & McLennan and Zurich Insurance Group, comes a month after the deal signed in Paris to reduce carbon emissions. The WEF said evidence was mounting that inter-connections between risks were becoming stronger. It cited links between climate change and involuntary migration or international security, noting that these often had “major and unpredictable impacts”. Espen Barth Eide, the WEF’s head of geopolitical affairs, said there was a risk of Europe fragmenting as a result of “people on the move”. Speaking at a press conference in London to launch the report, Eide said: “I am concerned about the continued support in national politics for keeping Europe together.” Read More here
