New research from Norway shows that the Gulf Stream has slowed down faster than anticipated, 5yrs ago it had slowed by 30% add another 10% & you've got where we're at now. I'll be glad when it stops, then we'll have winters similar to those they have in Labrador. I won't have to go abroad for some sking anymore, & it could be 3 months or more of good cold winter weather.
It will certainly set up many problems for the government to solve

Transport, power supply, food distribution, health & welfare to name but a few. Many people will suffer & die in this country but that is only the tip of the iceberg(no pun intended) what with the mix of peoples & cultures here, policing may become a problem. All this may never happen but the signs point in that direction. How long it will take for real winter to set in, who knows? But I feel it will.
