Cooling in the North Atlantic

Something is going on in the North Atlantic.

Paul Homewood notes the region is cooling rapidly and it is not just surface cooling, it applies to the 700m depth that Argo buoys measure. Graphs thanks to Ole Humlum.

To give it some perspective that cooling is back to temperatures of about 20 years ago (see below). This is localized, not global, but still interesting (rather especially to our European friends).

This is the area mentioned in a recent study on solar winds which found faster solar winds correlate with a cooler north Atlantic.

A year ago a different paper predicted colder times were coming to the North Atlantic due to natural cycles.

The man-made aerosols prediction that bit the dust…

A paper by Robsom et al in the last couple of weeks said that the cooling trend was clear, started in 2005 and really shouldn’t have happened if man-made aerosols were controlling the North Atlantic.

 ”Here we show that since 2005 a large volume of the upper North Atlantic nOcean has cooled significantly by approximately 0.45 C.”

“The observed upper ocean cooling since 2005 is not consistent with the hypothesis that anthropogenic aerosols directly [...]
