    Default Gulf Stream itself is not in danger of disruption

    .
    Typical eco-bollox from Moonshi'ite and the Guardian.

    As always this bullshit comes from climate models and not real world data.


    High-resolution climate models have projected a “decline of the Atlantic Meridional Overturning Circulation (AMOC) under the influence of anthropogenic warming” for decades (Lobelle et al., 2020). New research that assesses changes in the deeper layers of the ocean (instead of “ignoring” these layers like past models have) shows instead that the AMOC hasn’t declined for over 30 years.

    The North Atlantic has been rapidly cooling in recent decades (Bryden et al., 2020, Fröb et al., 2019). A cooling of “more than 2°C” in just 8 years (2008-2016) and a cooling rate of -0.78°C per decade between 2004 and 2017 has been reported for nearly the entire ocean region just south of Iceland. The cooling persists year-round and extends from the “surface down to 800 m depth”

    A 30-year reconstruction of the Atlantic meridional overturning circulation shows no decline

    Abstract
    A decline in Atlantic meridional overturning circulation (AMOC) strength has been observed between 2004 and 2012 by the RAPID-MOCHA-WBTS (RAPID – Meridional Overturning Circulation and Heatflux Array – Western Boundary Time Series, hereafter RAPID array) with this weakened state of the AMOC persisting until 2017. Climate model and paleo-oceanographic research suggests that the AMOC may have been declining for decades or even centuries before this; however direct observations are sparse prior to 2004, giving only “snapshots” of the overturning circulation. Previous studies have used linear models based on upper-layer temperature anomalies to extend AMOC estimates back in time; however these ignore changes in the deep circulation that are beginning to emerge in the observations of AMOC decline. Here we develop a higher-fidelity empirical model of AMOC variability based on RAPID data and associated physically with changes in thickness of the persistent upper, intermediate, and deep water masses at 26∘ N and associated transports. We applied historical hydrographic data to the empirical model to create an AMOC time series extending from 1981 to 2016. Increasing the resolution of the observed AMOC to approximately annual shows multi-annual variability in agreement with RAPID observations and shows that the downturn between 2008 and 2012 was the weakest AMOC since the mid-1980s. However, the time series shows no overall AMOC decline as indicated by other proxies and high-resolution climate models. Our results reinforce that adequately capturing changes to the deep circulation is key to detecting any anthropogenic climate-change-related AMOC decline.

    Climate models are as unreliable as opinion polls, Tom.

    But none of them live a green lifestyle. Not one.

    What does that tell you?

    WTF do you know about that. The entire magnetic pole may flip tomorrow for all you know.
    I hope it does and fucks your ability to post, dickhead.

    Why don't you debunk my link above? Surely I'm just a climate science denier. You should have an easy time destroying me, so why don't you give it a shot?

    Not really. He's supposed to be a smart dude and should have a handle on this rather simplistic theory if indeed CO2 drives climate. It should be child's play to debunk the crazy dude.

    Yet he cannot, apparently. He's nothing but a rage troll.

    I wish I could like your posts. I've been wishing that for a couple years at least now. I know it doesn't matter to you, but it would be nice to tell you how much I like your ideas
