Vaughan, if you believe the AMO can cause a 0.2 C difference in global temperatures and that is just a reflection of the transport of the AMOC then it stands to reason you would attribute something to a longer term speeding up of the AMOC as depicted in Lund 2006 reconstruction
of Gulf stream transport.
Environmentalist viewpoint — temperature increases caused by CO2 increases will cause tipping points where all sorts of bad things will happen such
as gulf stream reversal.
The melting of the Greenland ice sheet trigger accelerated sea level rise, a die back of the Amazon rainforest removes a crucial atmospheric carbon sink, and an alteration of the ocean conveyor belt shuts down the
Atlantic Gulf stream.
November Resolute Bay Nunavut Canada mean temperature anomaly was around +4.5 C. No
Gulf stream here, just incredible warming.
Tell us again how the California current is warm and warms the west coast and how the
cold gulf stream cools the east coast.
Avoid Gulf stream disruption at all costs, scientists warn by Damian Carrrington, Environment, Guardian, Apr 13, 2018
According to AdAge, the Anheuser - Busch InBev - owned (ahbif) beer will feature the word «America» on its front and will be adorned with various nationalistic phrases --» Land of the free, home of the brave,» «From the Redwood Forest to
the Gulf stream waters,» and «Indivisible since 1776» (apparently they forgot about the Civil War).
A northwards branch of
the gulf stream, the North Atlantic Drift, is part of the thermohaline circulation (THC), transporting warmth further north to the North Atlantic, where its effect in warming the atmosphere contributes to warming Europe.
Recent monitoring does suggest a significant weakening but debate continues over whether
the gulf stream may «switch off» as a result of the increased flows of fresh water from northern latitude rainfall and melting of the Greenland icecap.
I mean look at the recent results and findings for
the gulf stream around Europe, this is bad news but no climate scientist stuck their neck out and stated that this was even potentially catastrophic, just that more research needs to be done.
For example,
the Gulf stream system.
We know there is one because we know these non-linear phenomena are very sensitively dependent on the exact state of the system and so models still widely disagree on how stable or unstable
the Gulf stream system will be under global warming in the future.
The abundant rain and the warming influence of
the Gulf stream create hillside after hillside of thick green grass, ideal for dairy farming.
Gulf stream to yachting and traveling with someone great.
Goofily funny, and silly, and in many ways follows the currents of contemporary comedy into
the gulf stream of inanity.
The climate in Devon is similar to that in the rest of the South West peninsular, warmed by
the Gulf stream with often very hot summer days.
For instance, the book discusses the (essentially non-existent) effect of El Nino Southern Oscillation on
the Gulf stream; it is possible that the authors actually had the ocean currents off the Peruvian and Equatorial coasts in mind.
And the same it seems all over the polar region, must wait for official November data, but if the Arctic becomes permanently warmer this suggests that
a gulf stream failure may be catastrophic not as much for Europe but much worser for the South Atlantic.
Somebody needs to say here that hysteria about abrupt shutdown of the «
gulf stream» (sigh) is counterproductive with respect to critical thinking about the real ongoing effects of climate change like Tropical Glacier Retreat which few people seem interested in.
Now in
the Gulf stream, this isobar gradient would be expected to reinforce the frictional wind forces, while in the eastern atlantic, it would oppose the frictional wind forces (thus leading to the necessary imbalance between the arms of the gyre I noted above).
The question that remains is whether the required reduction in imbalance would be achieved by 1) a slowing of
the Gulf stream, 2) a speeding up of the Eastern half of the gyre, or 3) some combination of the two.
It seems like that shallow south flowing water must be warm (it's the portion of
the Gulf stream that's turned around and headed back south), and it's headed right where hurricanes form.
It goes likewise with western Europe, warming up with the rest of the world, and so
the Gulf stream heat supply may be replaced by tthe lack of cooling from the Arctic and Siberia, it would be a different climate, but no Icy Canadian Blizzards for East Anglia, unless the Arctic is normal.
i have been interested to find out lately how
the gulf stream is going?
One wonders how competent science writers could confuse THC with
the gulf stream?
And if you follow the immeadiately following link on the page, you get a discussion of
the gulf stream, and its possible shutdown, and a clear statement that modelling results don't show this (just a 20 % slowdown), and that the probablility of a shutdown is «low».
