It appears that the extent of Arctic Summer Sea Ice has reached its lowest recorded extent, falling below 4 million square kilometres. There is a striking visual representation of the change between 1979 and 2012 by the Guardian here.
It is also reported that this loss of arctic ice, may well bring a harsh winter across Europe. It appears that the jet stream is slowing down (as well as moving North) and that this is likely to mean prolonged periods of weather as they are not "pushed on", so perhaps longer periods of flooding and drought.
It seems to me that this highlights our urgent need for adaptation. If we are likely to face more extreme weather, like the 2003 heatwave and the 2005 floods then our current infrastructure is going to come under severe strain. Our systems must be examined and critical points strenghtened, we must build resilience into local and national systems as well as our individual lives.
