Global Warming Could Mean Global Cooling

Another article on what could happen if the the Atlantic Meridional Overturning Circulation (AMOC) slowed or collapsed: "The real-life Day After Tomorrow: The Gulf Stream could COLLAPSE as early as 2025 - plunging Europe into a deep freeze, scientists warn." The Daily Mail explains:

    The Gulf Stream is part of a much wider system of currents, officially called the Atlantic Meridional Overturning Circulation or AMOC. 

    Described as 'the conveyor belt of the ocean', it transports warm water near the ocean's surface northwards – from the tropics up to the northern hemisphere.

    When the warm water reaches the North Atlantic (around Europe and the UK, and the US east coast), it releases the heat and freezes. 

    As this ice forms, salt is left behind in the ocean water. 

    Due to the large amount of salt in the water, it becomes denser, sinks , and is carried southwards in the depths below.

    Eventually, the water gets pulled back up towards the surface and warms up in a process called upwelling, completing the cycle. 

    Scientists think AMOC brings enough warmth to the northern hemisphere that without it, large parts of Europe could enter a deep freeze.    

    Prior studies have already shown that due to climate change, the AMOC is slowing down. 

    The engine of this conveyor belt is off the coast of Greenland, where, as more ice melts from climate change, more freshwater flows into the North Atlantic and slows everything down.

    The new study forecasts that an abrupt shutdown of the AMOC could happen in the next few decades, rather than the next few centuries as previously thought. 

According to the article, if the AMOC collapsed, "the European climate will cool by about 1.8°F (1°C) per decade, and some regions will even experience over 5.4°F (3°C) cooling per decade – much faster than today’s global warming of about 0.36 F (0.2 C) per decade."

   Two points: First, the problem is not Greenland, which is not really losing ice cover no matter what the propogandists tell you, but the Beaufort Gyre, the largest freshwater reservoir in the Arctic, and which has increased its freshwater reserves by 40% since the 1970s. This could dump its fresh water into the North Atlantic and disrupt the AMOC. 

    Second, you will note that contrary to all the cries about a runaway greenhouse effect as certain propogandists have been crying about, the real impact will be colder temperatures and, consequently, less food. The sea levels will not rise; more likely, they will fall slightly. But, in any event, is explains why the wealthy are still buying up beach front property but adding bunkers and fences to keep the great unwashed masses away.
