from warming surface temperatures — will reduce heat - trapping high - cirrus clouds, which will help balance the planet's temperature.

warming the stratosphere instead.

Because the loss of CO2
from the atmosphere is
temperature sensitive (higher
temperature leads to more rain and more carbonate formation) but the source of the CO2 is
temperature insensitive (volcanoes do not care about the
surface temperatures), the whole cycle forms a net negative feedback cycle: higher
temperatures will result in cooling and lower
temperatures will result in
warming.
But, according to a new analysis in the journal Geophysical Research Letters by Ben Henley and Andrew King of the University of Melbourne, the 1.5 °C target may be reached or exceeded as early as 2026 if the Interdecadal Pacific Oscillation (IPO) shifts sea

from a cool to a
warm phase.

Any way you look it,
from the Climate Prediction Center Outlook through May, to the ongoing

It is also crucial in controlling your
temperature, having the role of an insulator against loss of body heat and the flow of
warm or cool blood
from and to the skin
surface which can be drastically hotter or colder in comparison to your internal body
temperature.
If a larger mass of
warm air has to pass through it, more energy is transferred, through the evaporator's fins (so that even the evaporator's design and, in particular, its exchange
surface play an important part)
from the air to the liquid refrigerant allowed inside it by the TEV or orifice tube so it expands more and, along with the absolute pressure inside the evaporator, the refrigerant's vapor superheat (the delta between the boiling point of the fluid at a certain absolute pressure and the
temperature of the vapour) increases, since after expanding into saturated vapour, it has enough time to catch enough heat to
warm up further by vaporizing the remaining liquid (an important property of a superheated vapour is that no fluid in the liquid state is carried around by the vapour, unlike with saturated vapour).
Even during the region's
warmest months, sea
surface temperatures can range
from 80 down to below 70 degrees, and winter may bring chilly waters in the mid 60s, and occasionally as low as 58 degrees.
«The observed pattern of

If you download 1998 - 2009 cloud cover here, and sea
surface temperatures here, you can see that, except for a cloud band
from ~ 0 to 10 degrees N, cloudiness is generally less where SST is
warmer, though there are lots of details and spatial variation that lessen the correlation.
411 SG Bolstrom, I am observing a particular trend unlike the recent past, whereas the Arctic air profiles are leaning more adiabatically during winter, this means a whole lot of confusion with respect to
temperature trends, namely the high Upper Air should cool as the
surface warms, and the reverse, the Upper air
warms when heat
from the lower atmosphere is transferred upwards.
We do not know what the MOC has actually been doing for lack of data, so the authors diagnose the state of the MOC
from the sea
surface temperatures — to put it simply: a
warm northern Atlantic suggests strong MOC, a cool one suggests weak MOC (though it is of course a little more complex).
Personally I got convinced that
warming was underway in the late 1990s after borehole measurements in rocks around the world, far away
from civilization, showed unmistakable evidence of
warming over the past century... if you log
temperature down the hole, you find that extra heat has been seeping down
from the
surface.
2) A better ability to constrain climate sensitivity

Item 8 could be confusing in having so many messages: «It is extremely likely that more than half of the observed increase in global average
surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas... The best estimate of the human - induced contribution to

These results suggest that sea
surface temperature pattern - induced low cloud anomalies could have contributed to the period of reduced
warming between 1998 and 2013, and offer a physical explanation of why climate sensitivities estimated
from recently observed trends are probably biased low 4.
By the way, low clouds in darkness increase
surface temperature, sort of like the inverse property of commonly understood Cosmic ray effect, not causing a cooling because there are more CR's, but rather a
warming, which only low clouds in total darkness can do, so the probable CR
temperature signal gets cancelled
from one latitude dark vs bright region to the next.
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.
There is definitely more to learn about how climate behaves and there are now data sets for ocean
warming and carbon dioxide distribution that could benefit
from better
surface temperature measurements.
Adding CO2 does not (at least not before the climate response, which is generally stratospheric cooling and
surface and tropospheric
warming for increasing greenhouse gases) decrease the radiation to space in the central portion of the band because at those wavelengths, CO2 is so opaque that much or most radiation to space is coming
from the stratosphere, and adding CO2 increases the heights
from which radiation is able to reach space, and the stratospheric
temperatures generally increase with increasing height.
Re Q # 3: The current answer ``... emission

surface» is a true fact but is not a valid answer to the question of how the greenhouse effect alters

The increased troposphere -
surface warming from more CO2 is best thought of by the rate of IR escape out the top of the atmosphere, which is reduced for a given
temperature.
The
surface gets
warmer because the thermal lapse rate, a structural element of the atmosphere *, is suspended
from a higher altitude and thus intercepts the
surface at a higher
temperature.
I was referring to the plot of absolute average
surface temperatures from different models against the projected rate of
warming for 2011 to 2070
from those same models; this is the next to last graphic
from Gavin's post.
What the CO2 (both «cold, hot and
warm CO2 ′) and other gasses do is to make the atmosphere more optically thick to thermal IR radiation emitted (mainly)
from the Earth's
surface [note2] which has consequences for the equilibrium
temperature profile of the atmosphere.
Let's see... many models show that aerosols could have been artificially keeping the world's average
surface temperature cooler by about 3 - 5 degrees C
from 1900 - 2000 --(sulfate aerosols certainly have some certifiable cooling effects cancelling out the
warming effects of CO2).
