Sentences with phrase «value of climate sensitivity»

These different measures put the likely value of climate sensitivity at about 2 - 4 °C per doubling of CO2.
So while the precise value of climate sensitivity poses an interesting scientific question, tackling the policy response is by far the bigger problem.
This implies a greater value of climate sensitivity than estimated in the 2006 paper.
That is a more complex matter as it will depend on the elusive value of climate sensitivity.
But while the exact value of climate sensitivity presents a fascinating and important scientific question, it has little relevance for climate policy while greenhouse emissions stay as high as they are.
If emissions stay as high as they are, that means even a low value of climate sensitivity would see a significant amount of warming by the end of the century.
We're emitting carbon dioxide so fast that the difference between a low and a high value of climate sensitivity is largely irrelevant in climate policy terms.
The likely value of climate sensitivity has large relevance for consideration of the likely magnitude of impacts from climate change in the future.
The key point here is that the range of values of climate sensitivity, and of aerosol forcing are small.
But then Archibald multiplies the radiative forcing by an absurdly low value of the climate sensitivity parameter.
But it turns out that climate scientists can do better than that: they can provide a distribution of possible values of climate sensitivity which attaches a probability of occurrence to a range of possible values.
To summarize: Hansen did not discover the greenhouse effect; the greenhouse effect is not the cause of AGW; the AGW is itself a pseudo-scientific fantasy; no runaway greenhouse effect is possible in the presence of water vapor; and finally, the true value of climate sensitivity is zero.
In the end, Archibald concludes that the warming from the next 40 ppm of CO2 rise (never mind the rest of it) will only be 0.04 degrees C. Archibald's low - ball estimate of climate change comes not from the modtran model my server ran for him, but from his own low - ball value of the climate sensitivity.
Archibald was doing fine until he introduced his unrealistic value of climate sensitivity parameter.
Using his PAGE09 model, he calculated an SCC of about $ 100 per ton of CO2 for generally accepted values of climate sensitivity (Hope does the analysis for transient climate response, a measure of climate sensitivity that is technically distinct from the ECS, but the effects on price should be similar).
«The fact that there is a distribution of future climate changes arises not only because of incomplete understanding of the climate system (e.g. the unknown value of the climate sensitivity, different climate model responses, etc.), but also because of the inherent unpredictability of climate (e.g. unknowable future climate forcings and regional differences in the climate system response to a given forcing because of chaos).
But arguments over the precise value of climate sensitivity duck the wider point, which is that even if we're lucky and climate sensitivity is on the low side of scientists» estimates, we're still heading for a substantial level of warming by the end of the century if greenhouse gas emissions aren't addressed, as the IPCC has highlighted.
A recent paper written by economist Martin Weitzman used an expected utility analysis to argue that the fat tail associated with unexpectedly but not impossibly high values of climate sensitivity dominate climate change economics.
Why would anyone invite me to write a paper, when all it would say is «Any numeric value of climate sensitivity, however defined, is nothing more than a guess.
The method used to calculate such low values of climate sensitivity fails to include important regional dynamics in the climate response, and this has been shown to bias it toward low values.
The most likely value of climate sensitivity from the AR4 [the fourth report from the Intergovernmental Panel on Climate Change] was about 3 degrees.
Another point worth making about the figure is that greater values of climate sensitivity likely translate into quicker evolution of the climate, all other things being equal (e.g., Bahn et al., 2011, Fig. 2).
A net forcing close to zero would imply a very high value of climate sensitivity, and would be very difficult to reconcile with the observed increase in temperature (Sections 9.6 and 9.7).
Sometimes various factors like aerosols or vegetation change aren't considered, and thus whatever effect they might have would just be lumped into the value of climate sensitivity value that emerges from this method.
Your personal opinion about the value of the climate sensitivity is not the consensus, but then you deny the consensus as stated by the IPCC by claiming that the IPCC, which was set up to determine the consensus, somehow is either deluded or lying about how they determined their results.
They show that this places a strong constraint on our ability to determine a specific «true» value of climate sensitivity, S.
