Of these forcings, the only non-human-induced forcing that
produces warming of the surface temperature is the estimated long - term increase by 0.3 W / m2 of solar irradiance since 1750.
Not exact matches
Most scientists and climatologists agree that weird weather is at least in part the result
of global
warming — a steady increase in the average temperature
of the
surface of the Earth thought to be caused by increased concentrations
of greenhouse gasses
produced by human activity.
«With
warmer sea
surface temperatures beneath the cloud, the coalescence process that
produces precipitation becomes more efficient,» team member Richard S. Lindsen
of M.I.T. explains.
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.
The researchers reported that the shifting winds «
produce an intense
warming» just below the
surface of the ocean.
On the other hand, if the ice shell is sufficiently thick, the less intense interior heat can be transferred to
warmer ice at the bottom
of the shell, with additional heat generated by tidal flexing
of the
warmer ice which can slowly rise and flow as do glaciers do on Earth; this slow but steady motion may also disrupt the extremely cold, brittle ice at the
surface to
produce the chaos regions.
The observed fact that temperatures increases slower over the oceans than over land demonstrates that the large heat capacity
of the ocean tries to hold back the
warming of the air over the ocean and
produces a delay at the
surface but nevertheless the atmosphere responds quit rapidly to increasing greenhouse gases.
With its vibrant palette
of warm golden colors and a
surface infused with painterly passion, Joan Mitchell's luxurious canvas, Blueberry, belongs to a group
of significant works which demonstrate the artist's unrivaled skill at
producing paintings which evoke the rich emotions
of nature and landscape.
There doesn't seem to be a secret that needs uncovering: when I ask what prompted him to move from the lush, textured
surfaces of the paintings he
produced in the 90s — canvases that seem to have a
warm bloom across them like a beautiful mould — to the flatter, looser, more painterly style he employs today, once again, he has no complex rationale.
The paintings in this series are
produced using the classical oil painting methods and materials
of the Old Masters — successive layers
of warm and cool black pigment glazes varnished to a highly reflective
surface resulting in a profoundly deep pictorial space.
Even in the absence
of huge amounts
of carbon dioxide as a forcing mechanism, he said, there still appear to be trigger points that, once passed, can
produce rapid
warming through feedbacks such as changes in sea ice and the reflectivity
of the Earth's
surface.
The basis
of the issue is that models
produce an enhanced
warming in the tropical troposphere when there is
warming at the
surface.
«We show that the climate over the 21st century can and likely will
produce periods
of a decade or two where the globally averaged
surface air temperature shows no trend or even slight cooling in the presence
of longer - term
warming,» the paper says, adding that, «It is easy to «cherry pick» a period to reinforce a point
of view.»
A stronger gravitational field will
produce a lower, denser,
warmer surface than a weaker gravitational field since the amount
of solar energy retained by the atmosphere will be focused into a smaller volume and that amount
of energy will be determined by the amount
of mass available to absorb it at any given level
of solar irradiation.
Right and that fundamental is that a doubling
of CO2 will increase atmospheric resistance to heat loss by about 3.7 Wm - 2 which could
produce 0.8 to 1.5 C
of warming depending at the
surface or
surfaces chosen as references.
Jim Cripwell is an idiot in the opinion
of the
warmers, because the physics is sound, «a doubling
of CO2 will cause 1 - 1.5 C
of warming at some
surface which will
produce some undetermined amount
of warming at the «true
surface» over some undetermined time frame.»
Produce evidence
of (a) the temperature
of the air adjoining the
surface being
warmer than the
surface at night, thus «stopping convection» and (b) any other inversion in calm conditions at night in the troposphere.
Absorption
of solar radiation by ozone shields the terrestrial
surface from harmful ultraviolet light and
warms the stratosphere,
producing maximum temperatures
of − 15 to 10 °C (5 to 50 °F) at an altitude
of 50 km (30 miles).
In climate - change discussions, two Princeton professors go against the grain By Mark F. Bernstein The issue
of climate change, or global
warming, has become a rallying cry: The Earthâ $ ™ s
surface temperatures are Ârising due to increased levels
of carbon dioxide and other Âgreenhouse gases in the atmosphere, much
of it
produced by human activity.
The «unnatural»
warming so far seen is however trended strongly to the alterations to the planetary
surface by Humanity over the past 400 years and the rebalance towards greater kinetic induction (in its cumulative effect) is now producing observable alterations not only to the Land Surface median Temperature, but to the Ocean (vie conduction / convection) and a still unconfirmed claim of a small overall rise in Median Atmospheric Temperature, which if «true» would place the Planetary Biosphere on the «Human Population Plot» with regard to «warming&

The extra boost from the
warmer water is adding even more energy into this storm system, increasing the availability and transport
of moisture toward land and
producing more efficient wind gusts to the
surface.
Heat picked up at the
surface is thus rapidly vertically mixed and transported by all three mechanisms — conduction, convection and radiation — acting at different length scales and with considerable and non-ignorable chaotic and self - organized emergent mesoscale structure — to
produce an atmosphere that, as you note, ends up somewhere between the DALR and isothermal most
of the time, although inversions (
warmer on top) or with a gradient even larger than the DALR happen all the time, and are unstable or transiently metastable states with some lifetime and break apart and perhaps reform somewhere else as the conditions that favor them recur.
«The ability
of a planetary atmosphere to inhibit heat loss from the planet's
surface, thereby enhancing the
surface warming that is
produced by the absorption
of solar radiation.
Steven, that would only be fair since warmists already have had their fun seeing skeptics squirm and disown thee efforts
of Judy's own BEST team to
produce a land
surface record that incorporates many more stations, and implements better algorithms, in order to correct alleged warmist biases in the CRU record, only to discover that the CRU
warming trend was biased low.
«Climate science» as it is used by warmists implies adherence to a set
of beliefs: (1) Increasing greenhouse gas concentrations will
warm the Earth's
surface and atmosphere; (2) Human production
of CO2 is
producing significant increases in CO2 concentration; (3) The rate
of rise
of temperature in the 20th and 21st centuries is unprecedented compared to the rates
of change
of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate
of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use
of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity
of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.
My personal views are: (1) Yes, it is true that increasing greenhouse gas concentrations will tend to
warm the Earth's
surface and atmosphere; (2) Yes, human production
of CO2 is
producing significant increases in CO2 concentration; (3) The rates
of change
of temperature in the previous two millennia are uncertain because proxies have been misapplied by the hockey stick crowd.
Collectively the processes
produce 20 to 30 year
warmer or cooler regimes
of Pacific Ocean sea
surface temperature — and abrupt shifts between that may be triggered by UV / ozone chemistry modulation
of the polar annular modes.
If this is the best such land area
surface temperature assessment system on the planet (covering, as well, a broad range
of metropolitan, suburban, and rural areas), and the quality
of the system is now proven to be demonstrably more prone to error than had been previously assumed — with the preponderance
of error shown to
produce the impression
of warming in excess
of real conditions prevailing — what may be reliably inferred about
surface temperature monitoring systems data from even less reliable thermometers all over the rest
of the world?
For example, atmospheric GCM simulations driven by reconstructed SSTs from the Pliocene Research Interpretations and Synoptic Mapping Group (Dowsett et al., 1996; Dowsett et al., 2005)
produced winter
surface air temperature
warming of 10 °C to 20 °C at high northern latitudes with 5 °C to 10 °C increases over the northern North Atlantic (~ 60 ° N), whereas there was essentially no tropical
surface air temperature change (or even slight cooling)(Chandler et al., 1994; Sloan et al., 1996; Haywood et al., 2000, Jiang et al., 2005).
Backing that up, NASA says that 1) sea
surface temperature fluctuations (El Niño - La Niña) can cause global temperature deviation
of about 0.2 °C; 2) solar maximums and minimums
produce variations
of only 0.1 °C,
warmer or cooler; 3) aerosols from natural sources such as volcanic eruptions (Mount Pinatubo for example) have caused average cooling
of 0.3 °C, but recent eruptions have had not had significant effect.
If countries were to start right away and build really fast, so that they installed a trillion watts
of gas - fired electricity generation steadily over the next 40 years, that would still add about half a degree Fahrenheit to the average
surface temperature
of the Earth in 2112 — that's within a tenth
of a degree
of the
warming that coal - fired plants would
produce by that year.
If heat flow into the deeper ocean (under 300m) is driven independently
of Global Average
Surface temperature or the «greenhouse» effect, then we have no reason to suppose that the latter
produces any «global
warming» at all.
Consider that just moving some
of the already
warmer surface water to depth (while some upwelling
of colder water occurs elsewhere as a compensation) results in an increasing heat content at depths while * simultaneously *
producing a decrease in heat content at the
surface.
Easterling and Wehner (2009) showed that «the climate over the 21st century can and likely will
produce periods
of a decade or two where the globally averaged
surface air temperature shows no trend or even slight cooling in the presence
of longer - term
warming.»
The constant flow
of relatively
warmer surface water that started in the mid 60s from the equitorial atlantic
produced a net increase in arctic ice melt, thus a colder southward current in the E Atlantic, giving the wrong impression
of generalised cooling in the region.
Eventually the
surface will cool sufficiently to
produce an observed reversion
of the
warming trend that increased the level
of «humidity».

Unseasonably
warm summers appear to be abetted by microbes and algae that grow on the increasingly wet
surface of the ice sheet,
producing pigments that boost the ice's absorption
of solar energy.
The quantitative details
of the
surface vs. TOA budget reasoning are discussed heavily in Ray Pierrehumbert's upcoming «Principles
of Planetary Climate» textbook, and he has also worked with David Archer to
produce a historical account if this type
of stuff in «The
Warming Papers» (though I haven't looked at this yet, if it's even available right now).
Second, even if the 3.7 W / m ² figure is correct, it could not possibly
produce 1.2 °C
of warming at the
surface.
(A major
warm - up predicted for sections
of West Antarctica will likely
produce surface melt as temperatures rise to above freezing.
