A slow stream

All reports about this seem to come from the same source, so one should not necessarily believe it, but it is kind of important, so let's just assume that it is true.

The Gulf Stream stopped.

It did not stop for ever. It is not all over. It is not a case of imminent winter and huge glaciers for all of Northern Europe.

However, it did stop for ten full days. And that is worrying enough. It does not make you think, because you do not know what to make of it, but it does make you worry.
