Fears over a slowdown in the north atlantic currents were more prevalent five years ago. Sudden changes are possible, but further research indicates that it is a lesser danger.And it is important to note that the research to which I was pointing in my post was not linking cold European winters of the last couple of years to ocean currents, but to ice cover.Gore's film was important and got a lot of things right, but actually sometimes majored on the minors.There are more pressing non-linearities that keep climatologists up at night these days. Arctic permafrost is probably the biggest one.
PS Though this is not to say that currents aren't changing.
