The only major potential drawback of baby wipe
warmers is the simple fact that they are a piece of electrical equipment that
heats up and is often in close contact to
water and wet
surfaces.
The more
heat in the Pacific, the bigger the El Niño, and right now, 150 metres below the
surface, a ball of
warm water is crossing that ocean.
So this effect could either be the result of natural variability in Earth's climate, or yet another effect of carbon dioxide and other greenhouse gases like
water vapor trapping more
heat and thus
warming sea -
surface temperatures.
Heat that stays at the
surface will ultimately result in greater sea - level rise as
warmer water expands more readily as it
heats up.
Charlie's research told him that during El Niño weather cycles, the
surface seawaters in the Great Barrier Reef lagoon, already
heated to unusually high levels by greenhouse gas — induced
warming, were being pulsed from a mass of ocean
water known as the Western Pacific
Warm Pool onto the reef's delicate living corals.
So, for example, a big part of what drives a hurricane is the fact that you've got a lot of
warm water near the
surface of the ocean that is transferring
heat into the air, and that's what's moving up, and that is a big part of then what's propelling the entire bigger storm system.
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.
Instead of dissipating into space, the infrared radiation that is absorbed by atmospheric
water vapor or carbon dioxide produces
heating, which in turn makes the earths
surface warmer.
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.
Without the periodic upwelling of cold
water associated with La Niña,
warm water would cover most of the
surface of the Pacific, releasing its
heat into an atmosphere already
warming because of climate change.
One result is a flow of cold deep
water toward the equator and
warm surface water toward the poles, and this «overturning circulation» plays a crucial role in moving
heat around the globe.
They generate energy from
heat just below the
surface;
water pumped down there is used to
warm fluids with low boiling points, releasing vapor that turns a turbine to make electricity.
With lots of
warm surface water releasing
heat into the atmosphere, in addition to ever - rising levels of greenhouse gases, 2015 is likely to surpass the
warmest year on record, and 2016 will be similarly hot.
i.e. the
water vapour will tend to carry
heat (in the form of
warmed air and latent
heat) higher in the atmosphere, reducing
surface warming.
At the same time, the
warm surface waters collect more
heat from the atmosphere as they move further westward, and form a
warm pool near New Guinea, Australia and the Philippines.
As an alternative, advise customers to melt a hole daily by setting a
heated pan of
warm water on the
surface.
The
warm water of the springs is from thousands of feet beneath the earth's
surface and because of the
heat and minerals the
water is super healthy for you skin.
A fluctuation in the location of slightly
warmer surface water could hardly cause the global increase in ocean
heat content.
The
warming being seen during the Autumn and Winter is mainly due to increased
heat fluxes from the
surface (Screen & Simmonds 2010) due to thinner ice and more open
water, so represents a net
heat loss to the atmosphere.
If as a result of physical processes (such as El Nino)
warmer water reaches the
surface of the ocean, so less
heat is conducted from the atmosphere into the ocean and the atmopsheric temperature will therefore increase — on a much shorter — comparatively instantaneous — timescale.
Think of what would happen if you could pump cold deep
water up to the
surface, increasing the air / sea temperature gradient and
warming the
water; that would give you an anomalously large ocean
heat uptake.
The
surface heat capacity C (j = 0) was set to the equivalent of a global layer of
water 50 m deep (which would be a layer ~ 70 m thick over the oceans) plus 70 % of the atmosphere, the latent
heat of vaporization corresponding to a 20 % increase in
water vapor per 3 K
warming (linearized for current conditions), and a little land
surface; expressed as W * yr per m ^ 2 * K (a convenient unit), I got about 7.093.
Corresponding time for
surface + tropospheric equilibration: given 3 K
warming (including feedbacks) per ~ 3.7 W / m2 forcing (this includes the effects of feedbacks): 10 years per
heat capacity of ~ 130 m layer of ocean (~
heat capacity of 92 or 93 m of liquid
water spread over the whole globe)
I recall mention that Katrina was unusual because while crossing the Gulf «Ring Current» the deeper
water pulled up by the hurricane was almost as
warm as the sea
surface, so the deeper
water fed almost as much
heat energy into the storm as the
surface.
(I think that an anomalously
warm ocean
surface heated from below would lead to more evaporation, and the additional
water vapor would give a positive greenhouse effect that would partially offset the effect of a drop in greenhouse gas concentrations.)
Alternatively, if a deepening of the subtropical gyres gives rise to an increase in the
heat stored in this
water mass, with a corresponding non-zero trend in the
surface heat flux; then I should think that a restoration towards conditions of the past must somehow give rise to a delayed
warming of the atmosphere (if the surplus is not somehow lost to space).
Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the
surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any
warming (aside from greenhouse feedbacks) and more so with a
warming due to an increase in the greenhouse effect (including feedbacks like
water vapor and, if positive, clouds, though regional changes in
water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be
warmer to begin with), the
heat capacity of the sea prevents much temperature response, but there is a greater build up of
heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).
The ocean's
surface begins to
warm, but before it can
heat up much, the
surface water is mixed down and replaced by colder
water from below.
The video loop above shows satellite readings of sea
surface height, an indirect measure of
heating (because of the way
warmer water expands).
Simple physics says that
warmer water is lighter, and therefore this
heat should rise to the
surface.
The increased area of
warm water on the
surface allows the tropical Pacific Ocean to discharge more
heat than normal into the atmosphere through evaporation.
Surface temperature is an imperfect gauge of whether the earth has been warmed by an imbalance between incoming radiation from the sun, and outgoing radiation, because of the role of ocean currents in the distribution of heat between deeper and surface
Surface temperature is an imperfect gauge of whether the earth has been
warmed by an imbalance between incoming radiation from the sun, and outgoing radiation, because of the role of ocean currents in the distribution of
heat between deeper and
surface surface waters.
The relatively
warm water flowing through the glacier also carries
surface heat deep inside the ice sheet far faster than it would otherwise penetrate by simple conduction.
This makes sense since
warming the
surfaces of the world's oceans would tend to decrease their CO2 - carrying - capacity, and this would be a slow process due to the buffering effects of the specific
heat capacity of these large bodies of
water.
Regarding the oceans: If it is not
surface heat that is
warming deep ocean
water, what is?
But again, I have to ask a question that you have not answered: How does the
heat trapped by CO2 at the
surface skin
warm the subsurface ocean
waters since it is widely acknowledged that the infrared
heat from CO2 can't penetrate into the ocean itself?
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.
The land in turn creates
warmer rivers which then enter the ocean and follow the bottom out to deep
water so for diving buoys that don't come near shore the
heat is not observed passing through the open ocean
surface.
The
surface of the ocean won't
warm as much, if at all, because its
heat is continually being pumped lower to be replaced by colder
water.
Sea ice can reflect solar energy to reduce
surface warming or insulate
water against
heat loss.
Water takes longer to
heat up and cool down than does the air or land, so ocean
warming is considered to be a better indicator of global
warming than measurements of global atmospheric temperatures at the Earth's
surface.
Climate Alchemy and probably most scientists not taught chemical thermodynamics don't realise that the main
heat transfer term in the oceans is the partial molar enthalpy transferred when the fresh, cold
water sinking from melting ice in the Antarctic and Arctic summers is made more saline when it mixes with the
warmer, more saline
surface water for which solar energy has partially unmixed the ions.
Schemes whereby currents could somehow move the
heat from the
surface to below 700m without
warming the first 700m on average have been proposed, and maybe some are plausible — but
warmer water rises.
At the moment, Lindzen is pursuing a theory that says increased amounts of
water vapor — from
warming surface temperatures — will reduce
heat - trapping high - cirrus clouds, which will help balance the planet's temperature.
You can't deduce anything using
heat conduction from
warm waters above because you'll find it's so tiny that would take ~ 125,000 years to
warm / cool the depths to same as
surface following a
surface MST anomaly if there were no currents bringing cold
water through, so obviously the actual
warming from
waters above is 99 % + by fluid mixing.
