Reposting: Jennifer Francis – “We’re in for an Interesting Fall and Winter”
October 29, 2012
My interview with Jennifer Francis of Rutgers last spring touched on the effects of newly open arctic waters on the jet stream, and extreme weather that may be resulting from that. We’ve seen a series of extreme events globally, including the Russian heatwave of 2010, Pakistan floods of the same summer, and the unusual spring in North America, that are related to behavior in the jet stream.
In the above interview I conducted this past September, Dr Francis re-iterated that, following the crash of northern sea ice over the summer, fall and winter might well be “very interesting”.
For the record, there is not by any means a smoking gun connection between arctic events and the current east coast frankenstorm – but nevertheless, here we are…
According to Kevin Trenberth, asking whether a particular event is connected to climate change, is in any case the wrong question – all weather going forward carries the signature of increased warming, and increased atmospheric moisture.
Below, see the Yale forum video that discusses the arctic connection to jet stream effects.
