known as a positive feedback.
This is
known as positive feedback.
A big reason for this is that they create the conditions that produce themselves,

known as a positive feedback.

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).
35, L20704, doi: 10.1029 / 2008GL035333, 2008], due to Andrew Dessler and his colleagues, who (
as you would
know) used the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite to show that the water - vapor
feedback is strongly
positive, tending to double the initial warming due to CO2 itself.
I personally think IPCC will lose less by openly conceding that clouds have always been «the largest source of uncertainty» and that it now appears that some of tis «uncertainty» is being cleared up, with the models
no longer predicting a net
positive cloud
feedback as before.
What you describe, if it happens, is in the same direction
as that which reduces the size of the so - called hot spot, and we
know that the hot spot would be a negative
feedback, so its weakening makes the total
feedback more
positive.
Of course Ferdinand is right not to project catastrophism onto anthropogenic CO2 levels for
as you likely
know there is a inverse logarithmic relationship between changes in temperature and CO2 levels such that without the assumed
positive feedback from water vapour there is no chance of runaway global warming, tipping points or whatever.
The implication of this statement is that there seems to be negative
feedbacks dominating rather than
positive feedbacks and that the Earth is still functioning well
as a repository for life
as we
know it.
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).
As we both know, physical observations of CERES satellites since AR4 was published (Spencer + Braswell) have shown that the net cloud feedback over the tropics is strongly negative, rather than positive, as assumed by IPC

Now they have described some of the
known knowns: we now
know without doubt that methane is venting to Earth's atmosphere from parts of the ESAS seabed in copious quantities
as a response - a
positive feedback - to warming.
But set some kind of time stamp or marks of when you
as an employer,
as the supervisor want to go in and give this employee
feedback whether it's
positive or critical and let them
know how they're doing because they would hate to be working on something incorrectly for a long period of time only to get that annual review and then not have time to adjust or shift.
Leaving a job when you have realized that it is
no longer a fit can be a peaceful process,
as long
as you keep your
feedback positive and make sure that you and your manager have a relationship that can handle the conversation.
