Study: There is no real evidence for a diminishing trend of the Atlantic Meridional Overturning Circulation

This paper was just published today in the Journal of Ocean Engineering and Science. It seems to be definitive refutation of Mann and Rahmstorf’s claims, and

quells the alarm bells that climate proponents have been ringing for years, not just in Mannian science that’s been refuted time and again, but in Hollywood movies like The Day After Tomorrow.

Doom and Gloom just isn’t happening when you look at the real-world data whereas Rahmstorf and Mann prefer to use computer models. In an email from the lead author Albert Parker, he noted:

[The AMOC is] apparently quite stable and not following the anthropogenic CO2 emissions

I’ll say:

There is no real evidence for a diminishing trend of the Atlantic Meridional Overturning Circulation

A. Parker, C.D. Ollier

Abstract

The Atlantic Meridional Overturning Circulation (AMOC) is part of the great ocean “conveyor belt” that circulates heat around the globe. Since the early 2000s, ocean sensors have started to monitor the AMOC, but the measurements are still far from accurate and the time window does not permit the separation of short term variability from a longer term trend. Other works have claimed that global warming is slowing down the AMOC, based on models and proxies of temperatures. Some other observations demonstrate a stable circulation of the oceans. By using tide gauge data complementing recent satellite and ocean sensor observations, the stability of the AMOC is shown to go back to 1860. It is concluded that no available information has the due accuracy and time coverage to show a clear trend outside the inter-annual and multi-decadal variability in the direction of increasing or decreasing strength over the last decades.
