ECO2 developed a generic approach for estimating consequences, probability and risk associated with sub-seabed CO2 storage based on the assessment of the environmental value of local organisms as indicated for example by the Natura 2000 network of nature protection areas or the Convention for the Protection of the Marine Environment of the North - East Atlantic (OSPAR), the vulnerability of environmental resources and possible impacts on them as well as consequences and risks.

According to a fascinating report from the Cleantech Group, called The Environmental Impact of Amazon's (s AMZN) Kindle, one e-Book device on average can displace the buying of about 22.5 physical books per year, and thus deliver an estimated savings of 168 kg of CO2 per year.

This causes estimates of the impact of CO2 on temperature to be understated, if one assumes no lag or a short lag; and to be overstated if one assumes longer lags.

What this model shows is that if orbital variations in insolation impact ice sheets directly in any significant way (which evidence suggests they do Roe (2006)-RRB-, then the regression between CO2 and temperature over the glacial - interglacial cycles (which was used in Snyder (2016)-RRB- is a very biased (over) estimate of ESS.

To estimate the ESS from these cycles you'd need to know what the separate impacts the CO2 and the orbital forcing had on the ice sheets, and that is not possible just from these data.

They do cite a study by Lindzen and Choi, which has shown, based on ERBE satellite observations, that the net impact of a doubling of CO2 including all feedbacks is likely to be significantly lower than the model - based estimates by Myhre for sensitivity without feedbacks.

Arrhenius spent a number of years trying to overcome this little obstacle before finally saying that the impact of CO2 was considerable less than his first estimate and mentioning 1.6 (2.1) with water vapor was more likely.

An updated estimate of the equilibrium climate sensitivity distribution (ECS)-- a measure of CO2's temperature impact — reduces the 2020 estimate of SCC by more than 40 percent; and

With the new ECS estimate, the absolute maximum AGW impact we could ever theoretically see from human CO2 is around 2.4 C warming above today, when all fossil fuels are 100 % used up.

That impact your estimate of the magnitude of CO2 forcing.

[7] Each individual estimate of the SCC is the realization of a Monte Carlo simulation based on a draw from an equilibrium climate sensitivity distribution to model the impact of CO2 emissions on temperature.

The model, which captures fuel use in the power, transport, and other energy sectors out to 2030, with fuel responsiveness parameterized to empirical literature, estimates the impacts of mitigation policies on CO2 emissions, revenue, premature deaths from local air pollution, household and industry groups.

In short, the temperature impact of CO2 is known within a significantly constrained range that excludes most denier estimates of the impact.

Now if you can figure out how much of the warming is due to CO2 and how much is due to longer term natural ocean «sloshing» around, then you can come up with an educated estimate of impact due to CO2.

What the three of you seem to be missing, it that it is becoming much more clearly understood that we still have much to learn regarding how CO2 impacts the actual earth climate and that Hansen and Mann over estimated its impact upon the system in total.

We are not yet able to physically measure the net forcing impact of increased CO2 concentrations, however, and must rely on model simulations to estimate this.

«Peak» land use, which impacts the carbon cycle, occurred before the estimate «peak» oil and is a more pressing issue in the long term than peak CO2.

One is that the IPCC forcing central estimate is 40 % larger than that from CO2 alone since 1950 (due to other GHGs and possibly reduced aerosol impacts relative to previous reports), so if you are going to use CO2 alone, you should really add this other 40 % to match what has happened since 1950 and that is what they did.

We can estimate how continuing to emit CO2 into the atmosphere will impact this.

«We can estimate how continuing to emit CO2 into the atmosphere will impact this [the sea level rise].»

Recent studies show that there is great «uncertainty» on the postulated theoretical temperature impact of doubling atmospheric CO2 concentrations, with latest estimates running around half the previous ones.

In any case, the impact estimates that I presented in my previous post were based on the worst case (A1FI) scenario which, according to the HadCM3 model, would increase CO2 concentrations to 810 ppm in 2085 and 970 ppm in 2100, and cause a 4 °C increase in average global temperatures between 1990 and 2085.

Do you think CO2 impacts are grossly over estimated?

Never mind the physics of CO2 or its counter theories... Never mind the balance of positive and negative feedback mechanisms... Never mind estimates of «impacts»... Nor even the merits and demerits of wind turbines... The climate debate is at its core about the form of politics that established itself in the late 20th century.

The extent of the offset depends on whether climate sensitivity to CO2 is on the larger or smaller end of the range of estimates, and the magnitude of the solar impact.

This is because our level of knowledge today is so rudimentary that we can not make any reasonable estimates of what the impact on climate of human CO2 emissions has been in the past or will be in the future.

Based on this information and published atmospheric CO2 data I can now estimate the CO2 impact on observed past warming and the observed 2xCO2 impact (or climate sensitivity), leaving out (for now) any notions of energy «hidden in the pipeline»..

Until someone can either corroborate and quantify (or falsify) the CO2 GH impact empirically, I'd be prepared to accept this estimate.
