Since, on average, aerosols have a cooling effect (although some absorbing aerosols like black carbon (soot) are actually adding to global warming), reducing current aerosol levels (particularly sulphates) is equivalent to
an extra warming effect.
Already, in areas where sulfur - rich fuels are regulated, the researchers find a significant
extra warming effect over 20 years.

effects from things like water vapour and ice loss will make it
warmer still
In
effect, O3 delivers global
warming via two routes: the 0.35 watt - per - meter - squared (w / m2)
extra heat it traps directly and the as much as 15 percent less vegetation that grows worldwide as a result of O3 damage.
This 2006 study found that the

Hang it on the shoulders for a chic
effect and have that
extra layer to keep you
warm!
It IS TRUE as Arrhenius showed in 1896, that more CO2 results in
extra absorbtions of energy photons, which results in a longer transport time hence
warming by CO2 (ie the Greenhouse
Effect.)
Its magnitude is consistent with the calculated greenhouse
effect —
extra warming from trapped heat radiation.
And I think this issue of climate sensitivity doesn't consider where those
extra GHGs come from and «nature's sensitivity» to the
warming & its many
effects.
Combine with Co2
warming the surface and it can just so happen that the two
effects cancel at the surface for a «pause» while the wind / current driven heating of the subsurface causes
extra heating in the subsurface.
Do you agree that when the heating
effect of
extra CO2 is due almost exclusively to what it itself absorbs from outside, but the cooling
effect entails an ability to dissipate heat from the additional source, cooling can now outweigh
warming?
A different perspective on the same problem: (try expanding your views a little) THE GREENHOUSE
EFFECT: The is no argument that
extra GHG absorbtion causes
warming within the radiative transport mechanism.
Some say that at the current level of 380 parts per million we are close to saturation as regards more
warming effect from
extra CO2.
Which explains why people always talk about the
effect of «doubling of CO2» rather than the more easy to understand «for each
extra 10ppm you get xK
warming»
Rider: If CO2 does help
warm the air (or the globe in general), does the
extra warmth disappear soon after, with no significant
effect on climate?
As a result, according to the data, there is no sign of any
EXTRA warming due to the green house
effect due to human emission of CO2.
Basically the same process occurs on Earth and other planets, and that is why we are at a «standstill» — because all the
extra carbon dioxide has no
warming effect whatsoever..
Many places refuse to turn over climate data, BEST adjusted and cherry picked much of the data they used, Coastal areas appear to be heavily
effected by coastal winds that are likely very very poorly documented, Non-coastal wind
effected areas seem to have little to no
warming, «Free» / online unadjusted data appears to be mostly at or near satellite data start thus provides little
extra info about the past, Looking for help from anyone who has Europe based original data outside of the «taxpayer funded yet refuse to turn over data to the public / taxpayer groups».
With the transformation of a Pacific typhoon into an
extra tropical cyclone we can easily see a direct link between a
warmer Pacific and he coming outbreak of cold weather next week in the US.The
effect on the jet stream is the key.
R. Gates: With the transformation of a Pacific typhoon into an
extra tropical cyclone we can easily see a direct link between a
warmer Pacific and he coming outbreak of cold weather next week in the US.The
effect on the jet stream is the key.
So if the atmosphere is not
warming, it means the
extra GHGs are having no significant
effect.
To add an
extra dose of comic opera to the whole thing, the image that accompanies Carroll's article is borrowed from the 2004 film The Day After Tomorrow, in which the
effect of global
warming is demonstrated by showing New York City covered in snow.
This 2006 study found that the
effect of amplifying feedbacks in the climate system — where global
warming boosts atmospheric CO2 levels — «will promote
warming by an
extra 15 percent to 78 percent on a century - scale» compared to typical estimates by the U.N.'s Intergovernmental Panel on Climate Change.
The greenhouse
effect from that
extra water vapor will then cause additional
warming that gets added to the original
warming from carbon dioxide.
Basically, Dr Ferenc Miskolczi's life as a NASA climate research scientist was made hell because he discovered that the
extra water vapour being evaporated is not having a positive - feedback (increasing the CO2
warming effect by absorbing more infrared from the sun), instead it is going into increased cloud cover, which reflects incoming sunlight back to space.
This
extra CO2, which has been stored underground for millions of years, is too much for the normal greenhouse
effect to manage, so the CO2 is capturing more of the sun's heat This is the main cause of global
warming.
The temperature to space re-equilibrates, but that means the surface is
warmer because of the
extra surface insulating
effect of the CO2.
Apart from albedo the
extra 45 W / m2 over high latitude (ice / snow free) landmass in summer would have a considerable
effect in
warming the climate.
That downwelling happens constantly even at night and worldwide and it has been theorised by global
warming proponents that
extra downwelling infrared from more greenhouse gases is at the heart of the proposed climate
effect from human sources of CO2.
Extra DLR has the same
effect but does not also provide additional energy to penetrate more deeply and make up its own deficit so that deficit also has to come from the DLR thus there can be no DLR left over to
warm the system.
While the rising temperatures of global
warming may be pushing the atmosphere towards greater extremes of weather - with all the destructive potential that implies - that
extra heat is also having an
effect on the oceans.
With other greenhouse gases it is responsible for the natural greenhouse
effect, and the
extra levels of CO 2 from burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, are causing the enhanced (or accelerated) greenhouse
effect which is why global
warming is happening.
Others accept (correctly) that that is unlikely due to the thermal inertia of our oceans and their cooling
effect on the air so they propose an «ocean skin'theory whereby
warming of the topmost molecules on the ocean surface from
extra downwelling infra red radiation from
extra human CO2 in the air is supposed to reduce the natural energy flow from sea to air so that the oceans get
warmer and then heat the air and kill us off that way.
As regards a
warming of the ocean skin, evaporation is a continuous process caused by temperaure, density and pressure (not just temperature) differentials between water and air so that the rate of evaporation accelerates when a water surface is
warmed such as from the
warming effect of
extra greenhouse gases (especially if the air is dry).
On that basis alone the cooling
effect of the oceans would dictate that it would take many millennia for any
warming effect in the air from
extra CO2 to become measurable let alone dangerous.
The suggestion that there are no solar
effects seems to contradict observations and the suggestion that
extra infra red
warms the oceans on timescales that are meaningful is against logic given the net cooling
effect of evaporation.
We've changed lots of other things, a little
extra warming may not only cause sudden climate change (The Gulf Stream is a frequently cited example), but help to prevent it or attenuate its
effects.
It is not seen that any «
extra energy» is surface incident at present, or such that is in any manner capable of creating unnatural
warming by a «greenhouse
effect».
De Witt, are you saying «THS???» because you don't know it stands for tropical hot spot [which I can't believe] or because you don't get the connection between backradiation and a THS, which I understood to be the case because the Troposphere would
warm faster than the surface since it is being heated by a
warmer surface, to wit, the surface of the planet which is getting
warmed by the aforesaid backradiation; and in addition to but not withstanding that the troposphere whould also rise which would be another aspect of the THS, with the final characteristic being that said THS would occur in the tropics where the
warming effect of
extra water would be most pronounced, also as a consequence of backradiation?
