    Default Science: The Deep Ocean Plays A ‘Leading Role’ In GW. It’s Colder Than in the 1700s

    McSquawker is always banging on about both Nature and Science journals, well here is a paper in Science. Shame that the smarmy shit is on a permaban!!


    Authors of a new paper published in the journal Science (Gebbie and Huybers, 2019) insist “the deep ocean ultimately plays a leading role in the planetary heat budget.” The global deep ocean has much less heat today than it had during both the Medieval Warm Period and the Little Ice Age.

    In rejecting their view [Spinoza, Leibnitz and Hegel], as I shall contend that we must, we are committing ourselves to the opinion that “truth” in empirical material has a meaning different from that which it bears in logic and mathematics.”

    What Caused the Medieval Little Ice Age? [video]

    Scientists have found that during the medieval Little Ice Age, the Gulf Stream's flow was 10 percent lower in volume than today's one. What caused that past diminishing of the Gulf Stream is still ...

    https://news.softpedia.com/news/What...eo-41383.shtml

    Between 1200 and 1850, Northwestern Europe had experienced a mini ice age. Legend has it that almost five centuries ago, England's King Henry VIII crossed the Thames River by horse on the frozen surface. The Thames used to freeze so often that London even had carnivals on the ice called the Frost Fairs. Here's a 1677 painting of the Frozen Thames by an unknown author (the Museum of London). The last Frost Fair was held in February 1814 and lasted only four days.

    A new study published in Nature argues that the cause of the mini ice age had to do with the weakening of the Gulf Stream. The Gulf Stream is a current in the Atlantic Ocean that takes warm water from the tropical mid-Atlantic up to Europe's western coastline. The warm water heats up the atmosphere and assures the mild western European weather in spite of the high latitude (Western Europe is at the same latitude as chilly Labrador).

    David Lund of the Californian Institute of Technology (Caltech) and his colleagues have studied the sediments from the region where the Gulf Stream enters the North Atlantic Ocean, called the Florida Straits. These sediments are made of a calcified species of plankton called foraminifera.

    The scientists detect the amount of the oxygen-18 isotope present in the sediment cores and use this data to deduce the past salinity and temperature of the seawater. Thus, the amounts of oxygen-18 can be used to determine ....

    The Little Ice Age - University of Washington

    - During the Little Ice Age, records show that this was a period of numerous volcanic eruptions. - As volcanoes erupt they spit particles and gases into the air, an event leading to the aerosol effect.

    https://www.atmos.washington.edu/199...ct2/group4.htm

    excerpt:

    5. Ocean-Atmosphere Conveyor System:
    -Occurs only in the N. Atlantic ocean-atmosphere domain.
    - Warm tropical Gulf Stream ocean currnts and winds are conveyed up to the north to meet cold Arctic waters and air.
    - Within this area you have atmospheric lows and highs:
    atm. lo: Forces air away from air mass center due to correolis effect. Outward tending winds will force ocean currents to diverge from the center as well.
    atm. hi: Opposite of atmospheric lo.
    - It is these divergent tendencies of the N. Atlantic that keeps the Gulf Stream powered. If an atm. hi replaced an atm. lo currents would converge, thus weakening the Gulf Stream which was thought to possibly have occured during the LIA.
    - Lack of warm winds and currents reaching the north would not warm the cold climate of the north possibly producing snow and ice.
    - This idea holds very sceptical because this event was localized, whereas the LIA was a global scale event.

    The researcher concluded that the cold water still trapped at depth from the Little Ice Age doesn't negate the warming of oceans above it. Kind of neat that the ocean is not as monolithic as it seems

    Will global warming trigger a new ice age? | Environment ...

    Without the Gulf Stream, temperatures in the UK and north-west Europe would be five degrees centigrade or so cooler, with bitter winters at least as fierce as those of the so-called Little Ice Age ...

    https://www.theguardian.com/environm...mment.research

    Excerpt:

    It is the Gulf Stream, and associated currents, that allow strawberries to thrive along the Norwegian coast, while at comparable latitudes in Greenland glaciers wind their way right down to sea level. The same currents permit palms to flourish in Cornwall and the Hebrides, whereas across the ocean in Labrador, even temperate vegetation struggles to survive. Without the Gulf Stream, temperatures in the UK and north-west Europe would be five degrees centigrade or so cooler, with bitter winters at least as fierce as those of the so-called Little Ice Age in the 17th to 19th centuries.

    The Gulf Stream is part of a more complex system of currents known by a number of different names, of which the rather cumbersome North Atlantic Meridional Overturning Circulation (Namoc) is probably the most apt.

    This incorporates not only the Gulf Stream but also the cold return currents that convey water southwards again. As it approaches the Arctic, the Gulf Stream loses heat and part of it heads back to warmer climes along the coast of Greenland and eastern Canada in the form of the cold, iceberg-laden current responsible for the loss of the Titanic.

    Much, however, overturns - cooling and sinking beneath the Nordic seas between Norway and Greenland, before heading south again deep below the surface.

    I recall when ALBERT claimed the GS was slowing and was going to stop, causing an Ice Age. So we spent a bunch of money studying it, and scientists discovered it was actually accelerating.

    All hail the Goracle.

    I condemn the National Socialist German Workers Party, the Socialist Democrat Hate Whitey Party,... and Socialist Workers party heroes, Mao, Chavez, Mussolini, Pol Pot, Stalin, Castro and Kim Jung Un.

    The process is a very slow one, measured over hundreds of years.

    Seriously, if you are going to post something at least try and find something newer than 15 years ago!!

    What was Havana Moon doing in the deep ocean in the 1700's? Drowning, I imagine!
