An increase in rain and meltwater from melting glaciers reduces the salinity of the sea off Norway and hinders the sinking of warm water. This causes the Gulf Stream to "back up" and slow, since it is the sinking of cooling water off Norway that powers the "global thermal conveyor belt" that carries warm seas up from the equatorial climes to northern Europe. If this weakening is permanent, it would lead to a cooling of the British Isles, and much colder winters.
Seems to indicate an exacerbation of our energy supply problem. British houses are poorly equipped to withstand cold winters. Britain's stock of brick Victorian terraces must be amongst the crumbiest housing stock in Europe. They won't last forever anyway.
