With an El Niño now under way —
meaning warm surface waters in the Pacific are releasing heat into the atmosphere — and predicted to intensify, it looks as if the global average surface temperature could jump by around 0.1 °C in just one year.
Not exact matches
A new El Niño cycle —
warmer surface waters — began last summer, which may
mean that stratospheric
water levels could change again.
Because
water expands as it
warms, that heat also
meant that sea
surface heights were record high, measuring about 2.75 inches higher than at the beginning of the satellite altimeter record in 1993.
In general, the regions of expanding
warming upwelling
water in the Indian Ocean, North Pacific, or wherever they are, must create slight bulges in the
surface, and the regions of shrinking, cooling, sinking
water in the Arctic must create slight depressions in the sea
surface (again, I
mean in a very low pass sense — obviously storms, tides, etc, create all kinds of short - terms signals obscuring this).
The
water vapor cooled the Earth, the snow cooled the atmosphere with resulting increase in
surface albedo which does reflect radiative heat,
meaning the Earth gets less
warm, not colder because of it.
Other experts point out one of the biggest natural factors behind the plateau is the fact that in 2008 the temperature cycle in the Pacific flipped from «
warm mode», in which it had been locked for the previous 40 years, to «cold mode»,
meaning surface water temperatures fell.
The
warmer the ocean becomes, the less
water rises from deeper down,
meaning fewer resources will be brought to the
surface water where phytoplankton live.
New Dutch research has shown for instance the overturning has been relatively weak in recent years [which
means cold
water has accumulated close to the
surface instead of sinking to deeper
waters, one of two reasons why there has been a lull in upper ocean
warming].
Francisco (09:12:57): Go ahead and explain how additional heat in the atmosphere moves from the atmosphere to the ocean
surface, and from there to the deep oceans, ** without first producing any
warming in the atmosphere or on the ocean
surface water ** Just because you don't know how it can happen, does not
mean that it is not happening, just that you don't understand how.
Many readers seem to think the «+»
means positive as in «
warm surface water» and that, conversely, the «--»
means negative as in «cold
surface water».
In 1997 and 1998 there was a strong El Nino event in the equatorial Pacific,
meaning that the
surface water there was unusually
warm.
The hurricane churned up
water 100 or even 200 meters below the
surface, said Trenberth, but this
water was still
warm —
meaning that the storm could keep growing and strengthening.
Presumably you
mean a patch of
water on the ocean cooled by a value D degs.C would reduce the
surface temperature by more than an equal and opposite patch of
water warmed by D Degs.C would
warm it *.
With 2), there's still something I don't get... and this applies just as much to your answer as to any answers you would get from climate science, since clouds are clouds (i.e droplets of
water), and
water vapour is a gas, so their back - radiation explanation doesn't even apply in the case of clouds (not saying it physically could apply anywhere but hopefully you get what I
mean)... what I don't get is, you liken them to a blanket, but a blanket is next to you, clouds are separated from the
surface by quite a bit of atmosphere — so why is it
warmer the next morning at the
surface when the clouds are there?
This would make the
surface ocean less salty, which (along with the
warming) makes the
surface waters less dense, and less likely to sink,
meaning that the AMOC would weaken or maybe collapse completely.
Yet an increase in the
surface area of crevasses can accelerate the flow because it
means more of the ice's interior is exposed to
warming by
surface melt
water.
It
means that the global sea
surface temperatures used by Endersbee in his calculations have been controlled by
warming of the sea
surface waters outside the tropical sea
surface i.e. mainly the
warming of the sea
surface waters of higher latitudes where the sea
surface CO2 sinks are.
Because the temperature gradient in a planet's troposphere is the state of thermodynamic equilibrium which the Second Law of Thermodynamics says will evolve, the planet's supported
surface temperature is autonomously
warmer than its
mean radiating temperature, so
warm in fact on Earth that we need radiating gases (mostly
water vapour) to reduce the gradient and thus cool the
surface from a
mean of about 300K to about 288K, this being confirmed by empirical evidence (as in the study in my book) which confirms with statistical significance that
water vapour cools rather than
warms, all these facts thus debunking the greenhouse conjecture.

Note: LOTI provides a more realistic representation of the global
mean trends than dTs below; it slightly underestimates
warming or cooling trends, since the much larger heat capacity of
water compared to air causes a slower and diminished reaction to changes; dTs on the other hand overestimates trends, since it disregards most of the dampening effects of the oceans that cover about two thirds of the Earth's
surface.
What they forget to mention is that this
warming is not by radiative
means but simply by the latent heat in
water vapour stolen from what would have been a
warmer surface.
The «note» you refer to goes: «Note: LOTI provides a more realistic representation of the global
