At the same time, there are particular areas of uncertainty, or of lower precision, that give rise to some ranges and degrees (within limits) of uncertainty when it comes to making forecasts of the degree of warming.

Refering to bands where optical thickness is constant over the interval of each band, if the atmospheric LW absorption is limited to some band (that doesn't cover all LW radiation), than increases in OLR in response to surface warming will occur outside that band, so OLR will drop within the band — there will still be some portion of stratospheric or near - TOA cooling that will be transient, but some will remain at full equilibrium.

Warming must occur below the tropopause to increase the net LW flux out of the tropopause to balance the tropopause - level forcing; there is some feedback at that point as the stratosphere is «forced» by the fraction of that increase which it absorbs, and a fraction of that is transfered back to the tropopause level — for an optically thick stratosphere that could be significant, but I think it may be minor for the Earth as it is (while CO2 optical thickness of the stratosphere alone is large near the center of the band, most of the wavelengths in which the stratosphere is not transparent have a more moderate optical thickness on the order of 1 (mainly from stratospheric water vapor; stratospheric ozone makes a contribution over a narrow wavelength band, reaching somewhat larger optical thickness than stratospheric water vapor)(in the limit of an optically thin stratosphere at most wavelengths where the stratosphere is not transparent, changes in the net flux out of the stratosphere caused by stratospheric warming or cooling will tend to be evenly split between upward at TOA and downward at the tropopause; with greater optically thickness over a larger fraction of optically - significant wavelengths, the distribution of warming or cooling within the stratosphere will affect how such a change is distributed, and it would even be possible for stratospheric adjustment to have opposite effects on the downward flux at the tropopause and the upward flux aWarming must occur below the tropopause to increase the net LW flux out of the tropopause to balance the tropopause - level forcing; there is some feedback at that point as the stratosphere is «forced» by the fraction of that increase which it absorbs, and a fraction of that is transfered back to the tropopause level — for an optically thick stratosphere that could be significant, but I think it may be minor for the Earth as it is (while CO2 optical thickness of the stratosphere alone is large near the center of the band, most of the wavelengths in which the stratosphere is not transparent have a more moderate optical thickness on the order of 1 (mainly from stratospheric water vapor; stratospheric ozone makes a contribution over a narrow wavelength band, reaching somewhat larger optical thickness than stratospheric water vapor)(in the limit of an optically thin stratosphere at most wavelengths where the stratosphere is not transparent, changes in the net flux out of the stratosphere caused by stratospheric warming or cooling will tend to be evenly split between upward at TOA and downward at the tropopause; with greater optically thickness over a larger fraction of optically - significant wavelengths, the distribution of warming or cooling within the stratosphere will affect how such a change is distributed, and it would even be possible for stratospheric adjustment to have opposite effects on the downward flux at the tropopause and the upward flux awarming or cooling will tend to be evenly split between upward at TOA and downward at the tropopause; with greater optically thickness over a larger fraction of optically - significant wavelengths, the distribution of warming or cooling within the stratosphere will affect how such a change is distributed, and it would even be possible for stratospheric adjustment to have opposite effects on the downward flux at the tropopause and the upward flux awarming or cooling within the stratosphere will affect how such a change is distributed, and it would even be possible for stratospheric adjustment to have opposite effects on the downward flux at the tropopause and the upward flux at TOA).

If governments are to keep the pledge they made in Copenhagen to limit global warming within the «safe range» of two degrees Celsius, they are running out of time, according to two sobering papers from Nature.

If we're successful — and world leaders make the kind of emissions reduction commitments that can keep warming within safe limits — the upshot is that we're going to have to scale down our use of fossil fuels as a planet and scale up renewables in a big, big way.

And after another quick scan, I find table SPM.6 from the Synthesis which says emissions would need to peak sometime before the middle of the century to limit temperature rises to under 4 degrees (with a peak by 2015 to achieve less than 2 degrees warming)... I think most would agree that some degree of «drastic action» is going to be required to achieve a peak in emissions within this time frame, particularly while we have guys like you running around, would you not?

This can effectively give investors a sense of what proportion of the company's investment plans may fail to deliver an acceptable return in the scenario of a world limited to 2 °C global warming outcome (i.e. which project capex is within budget and which is «unneeded»).

Integrated assessment models limit warming to well below 1.5 C warming in the year 2100, while other approaches avoid any exceedance within the next century.

Precision in data means that you are certain within statistical limits — there has been no statistically significant warming since 1998.

The reality is that man - made global warming is a myth: the global temperature is well within life's limits and, indeed, the present day is cooler by comparison to much of Earth's history.

The transparent screen allows the solar radiation to warm the ground, and the ground in turn warms the air, but only the limited amount within the enclosure.

But there can be other hopes that, although they're looking dim for now, are at least within reach: that greenhouse warming can be limited sufficiently to allow communities around the world who are currently impoverished and oppressed to improve their lives; that access to food, water, shelter, safety, culture, nature, and other necessities becomes sufficient for all; or that exploitation and oppression of humans and nature be brought to an end.

A hellish vision of a world warmed by 4C within a lifetime has been set out by an international team of scientists, who say the agonisingly slow progress of the global climate change talks that restart in Mexico today makes the so - called safe limit of 2C impossible to keep.

South Afrrica, despite being a non-Annex 1 country, has acknowledged its status as the highest ghg emitter on the African continent and announced a voluntary emissions reduction target, the objective of which is to make a «fair contribution'to keep global concentrations within the range required to keep within the 2 degree C warming limit.

Whether a 2C or a 1.5 C goal, limiting global warming is only achievable if global anthropogenic greenhouse gas emissions reach zero within this century.

These targets are less transformational than many of those contained in the mishmash of options currently contained within the draft of the UN's climate deal, which aims to reduce greenhouse gas emissions enough to have adecent chance of limiting warming to two degrees above pre-industrial levels.

The point here is, we need a rapid transition to renewable (energy), and avoid committing to long - term fossil fuel use if we are to get within the limits (of reducing global warming to less than 2 C).»

However, adaptive evolution of populations at the warmer range limit of a species will be limited by the amount of genetic variation and covariation within populations for traits affecting climate tolerance (Hoffmann and Sgro, 2011; Shaw and Etterson, 2012).

The world has agreed to limit average global warming to 2 °C, and to do that means that the world has to work within a strict carbon budget.

The above chart by the Global Commons Institute compares INDCs filed by nations with the UNFCCC before Paris with the reductions that would be needed by the entire world to live within carbon budgets that may not be exceeded if warming will be limited to; between 3 degrees and 4 degrees C, a 50 % chance of limiting warming to 2 degrees C, a 66 % chance of limiting warming to 2 degrees C, and a reasonable chance of limiting warming to 1.5 degrees C.

In this paper, Broecker correctly predicted «that the present cooling trend will, within a decade or so, give way to a pronounced warming induced by carbon dioxide», and that «by early in the next century [carbon dioxide] will have driven the mean planetary temperature beyond the limits experienced during the last 1000 years».

As a result, CO2 emission reduction rates are more severe than other scenarios that would still limit warming to within 2 °C and also include reductions in other gases.

The upshot of all the latest research, however, is that while limiting warming to 2 degrees is seeming unlikely, and 1.5 degrees nearly impossible, staying within something like 2.5 degrees still seems quite possible if there's concerted action.
