«Our observation that plants use roughly the same amount of water regardless of water availability suggests that a
warmer or longer growing season may
have a relatively small
effect on evapotranspiration and
thus could affect landscape water balances less than we previously thought,» Hamilton said.
The observed amount of
warming thus far
has been less than this, because part of the excess energy is stored in the oceans (amounting to ~ 0.5 °C), and the remainder (~ 1.3 °C)
has been masked by the cooling
effect of anthropogenic aerosols.
Thus far, Kepler
has found 48 planetary candidates in their host star's habitable zone (of which 10 are near Earth - size), but this number is a decrease from the 54 reported in February 2011 only because the Kepler team is now applying a stricter definition of what constitutes a habitable zone around stars to account for the
warming effect of planetary atmospheres, which
would move such a zone away from the star, outwards in orbital distance resulting in longer orbital periods (NASA news release; and Kepler Press Conference slides — in pdf).
Critics
have embraced the game with a
warm reception with 30 perfect scores awarded
thus far and Metacritic ranking Mass
Effect 3 at 94, 92 and 91 on Xbox 360, Windows PC, and PlayStation 3 respectively.
It seems that at least the regional
effect of aerosols in S.E. - Asia is
warming, not cooling...
Thus any reduction there
would have a cooling
effect.
This is a peer reviewed paper by respected scientists who are saying that aerosol forcing means that the majority of the
warming caused by existing co2 emission
has effectively been masked
thus far, and that as aerosols remain in the atmosphere for far shorter a duration of time than co2, we will
have already most likely crossed the 2 degree threshold that the G8 politicians
have been discussing this week once the cooling
effect of aerosols dissipate.
Thus an increase of average temperature, due to global
warming (which
has most
effect in winter), will reduce average mortality, not increase it...
Keeping within a sufficiently small range of wavelengths that the
effects discussed in 438 can be set aside, What such band widenning
would do, without a surface temperature increase, is simply increase the range of wavelengths at which the same temperature variation accomplishes the same spectral fluxes through the band,
thus not changing OLR within the band — the
warming that results from such band - widenning should
thus tend to increase the OLR within the band.

Thus the 1998 super El Nino induced global
warming was a secondary
effect of short - wave ocean heating, not necessarily recent, and
had very little to do with GHG.
You'll note an acceleration of those temperatures in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that
had a cooling
effect on the climate, and
thus were masking some of the global
warming signal.
I
'd like to stick to facts: * CO2 levels are rising because we emit CO2 (so we can do something about it) * CO2 is a greenhouse gas * CO2
thus contributes to
warming of the surface * Other
effects compensate or amplify these changes * Those other
effects haven't reversed / stopped the
warming trend yet
This analysis focused on the relationship between cumulative CO2 emissions budgets and the odds of staying below 2 °C of
warming, and
thus had the important side
effect of establishing cumulative budgets (in this case over the 2000 - 2050 period) as the best predictors of success for any given global emissions pathway.
Human emissions are quite different in composition as some also contain brown / black soot which may absorb more sunlight and
thus may
have more a
warming than a cooling
effect (especially over India).
Thus it is entirely unsurprising that these short - term
effects all aligning in the cooling direction in recent years
have offset much of the surface
warming caused by human greenhouse gas emissions.
By examining the spatial pattern of both types of climate variation, the scientists found that the anthropogenic global
warming signal was relatively spatially uniform over the tropical oceans and
thus would not
have a large
effect on the atmospheric circulation, whereas the PDO shift in the 1990s consisted of
warming in the tropical west Pacific and cooling in the subtropical and east tropical Pacific, which
would enhance the existing sea surface temperature difference and
thus intensify the circulation.
They say that world
would actually
warm up by just 1.64 °C overall, and the vegetation - cooling
effect would be stronger over land to boot —
thus temperatures on land
would would be a further 0.3 °C cooler compared to the present sims.»
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».
The postponement of the logging
has been enacted in the hope that the trees will absorb carbon dioxide (CO2),
thus mitigating the
effects of global
warming.
This means that volcanic aerosols
have minimal long - term cooling
effects and therefore, the
warming effect of CO2
has to be much lower than assumed in Hansen's climate models and
thus climate sensitivity estimates must be lowered even further.
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.
High solar activity means a stronger heliospheric magnetic field and
thus a more efficient screen against GCR, then under the hypothesis underlined above, the reduced GCR flux
would promote less clouds amplifying the
warming effect expected from high solar activity.
And before anyone starts to argue that we
have left out the direct (i.e., local)
effect of global
warming — that
warmer air holds more moisture and
thus it can rain more frequently and harder — McCabe and Wolock report very few long - term trends that
would be indicative of steadily rising moisture levels.
Thus, the 240 Watts / m ^ 2 of visible and near - visible Solar energy that reaches and is absorbed by the Earth System,
has the
effect of
warming the Earth System exactly as much as an equal number of Watts / m ^ 2 of «thermal» mid - and far - IR radiation.
Thus, it seems you are correct that there are factors in addition to the Atmospheric «greenhouse
effect» that account for the Surface being
warmer than it
would be absent that back radiation.
Moreover,
thus far, the environmental scientists
have yet to demonstrate empirically any cause and
effect relationship between human activity and global
warming.
So if the IPCC were to acknowledge that any of those natural
effects had any influence on temperatures, they
would have to reduce the amount of
warming scored to CO2 between 1978 and 1998 and
thus their large future
warming forecasts
would have become even harder to justify.
Although previous research
had seemed to indicate that aerosols could create a general cooling
effect in the atmosphere —
thus helping mitigate the
effect of global
warming — a new study
has revealed that they may in fact
warm it just as much as greenhouse gases.
