The Atlantic air and water currents have gone low. It is at the point on the nose when the current suddenly zooms south. It is my hypothesis that when it does that, we're in for a cold one. While I've been watching the chart (for a few years), the current has gone as far as this, but not enough to divert current. We'll watch it.
I'd be so proud of my baby, if it did gush the other way. Nobody has ever come up with this mechanism for ice ages. I love it!
ps. sea temperatures are showing the plunge already.
This map is updated more often than the current map, so I expect to see a diversion next time.
