Seeing this as a baseline, positive CO2 feedback
from temperature changes, or a running out of capacity for greater uptake
from CO2 accumulation, would be seen as adding more CO2 to the
air in addition to anthropogenic releases, but it would have to surpass some level before it would result in a total atmospheric accumulation of CO2 greater than anthropogenic emissions (first, as a rate, and later, cummulative
change).
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).

No energy is added or removed

Here we apply such a method using near surface

From an OSU press release: CORVALLIS, Ore. — An analysis of 35 headwater basins in the United States and Canada found that the impact of warmer

Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water
from plants lead to more rapid drying of soils if the effects of higher
temperatures are not offset by other
changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat
from the sun goes into heating the soil and adjacent
air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6
So water dances at many speeds,
from the unimaginable fast vibrations of its molecules responding to thermal infrared radiation, to the moment - to - moment dance of its phase
changes in response to
temperature changes, to the week - long dance of its vapor in and out of the atmosphere, to the slow geological pavanes of rock,
air and life, of which it too forms an inextricable part.

The NAO's prominent upward trend
from the 1950s to the 1990s caused large regional
changes in
air temperature, precipitation, wind and storminess, with accompanying impacts on marine and terrestrial ecosystems, and contributed to the accelerated rise in global mean surface
temperature (e.g., Hurrell 1996; Ottersen et al. 2001; Thompson et al. 2000; Visbeck et al. 2003; Stenseth et al. 2003).
The study uses recently updated surface

Yet the pot is very very large and can take decades to finish moving... So we end up with rapid
changes of
air temperature sometimes in response to sun modulation; but longer term
changes in sea
temperature and a «lag time»
from that showing up in longer slower
air temperature change.
2) If minor
changes in the
air attempt to make the
air temperature alone diverge
from that equilibrium then the weather systems
change to modify the energy flow and in due course restore the surface
air temperature to match the sea surface
temperature set by the oceans.
To point out just a couple of things: — oceans warming slower (or cooling slower) than lands on long - time trends is absolutely normal, because water is more difficult both to warm or to cool (I mean, we require both a bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase
change inside oceans, so no latent heat) or oceans begin to release heat but in the same time they have to cool (because they are losing heat); so, I don't feel strange that in last years land
temperatures for some series (NCDC and GISS) can be heating up while oceans are slightly cooling, but I feel strange that they are heating up so much to reverse global trend
from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this effect, I would not exclude it
from having a small part in
temperature trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands»
temperatures are often measured in a not so precise way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters»
temperatures trend; — metropolis and larger cities
temperature trends actually show an increase in UHI effect, but I think the sites are few, and the covered area is very small worldwide, so the global effect is very poor (but it still can be sensible for regional effects); but I would not run out a small warming trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than
air during day, and how much it can slow night - time cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a full view of UHI effect (still remembering that it has a small global effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).
Such oceanic
temperature as now subsists would probably be a historical inheritance
from a long past state possibly at the end of the last ice age when it was reset by a combination of
changed energy throughput
from the sun plus the resistor effect of the oceans and
air combined with the then state of the
air circulation.
Now in its 10th year, the Arctic Report Card provides the latest Arctic observations
from an international team of more than 70 scientists in 10 countries about

The latest climate science shows that in addition to climate mitigation, the world will need to remove carbon
from the
air and store it if we are to have a good chance of achieving the global goals of limiting
temperature rise to 1.5 - 2 degrees C (2.7 - 3.6 degrees F), the
temperature limit countries agreed to as part of the international Paris Agreement on climate
change.
There are plenty of ways of looking at the surface
air temperature record that all show no statistically significant
change in trend
from earlier decades, so any study that concludes sensitivity is different just with the addition of the past decade must be automatically suspect, and that's not even taking into account the heat going into the oceans.

If the negative effects of climate
change, the rising
air temperatures, the

from the
air or reflect sunlight back out of the atmosphere before it warms the earth.
