For example, the absence from AR5 of last January's Ramanathan paper indicating a large and very significant Albedo Loss feedback forcing can not be rectified until about 2019 under the current system of periodic IPCC reports advising the UNFCCC as to the climate predicament.

However, these feedbacks are part of the real climate system, as recognized in the IPCC's most recent Assessment Report (the AR - 5).

The presence of feedback effects and tipping points calls into question some of the most fundamental assumptions of climate change negotiations, including the belief that we can «overshoot» to, say, 550 ppm and then work back to 450 ppm (the path advocated in the Stern and Garnaut reports), that greenhouse gas concentrations in the atmosphere can be stabilised at some level, and the belief that we can adapt to some given degree of warming.

The «Physical Science» report finds that negative feedbacks in the climate system reduce the model model derived temperature sensitivity to values an order of magnitude smaller.

Webb et al (2013)[ix], who examined the origin of differences in climate sensitivity, forcing and feedback in the previous generation of climate models, reported that they «do not find any clear relationships between present day biases and forcings or feedbacks across the AR4 ensemble».

and add up to 1.5 °F to warming in 2100 by itself, «Participating modeling teams have completed their climate projections in support of the [IPCC's] Fifth Assessment Report, but these projections do not include the permafrost carbon feedback.»

It is intellectually dishonest to devote several pages to cherry - picking studies that disagree with the IPCC consensus on net health effects because you don't like its scientific conclusion, while then devoting several pages to hiding behind [a misstatement of] the U.N. consensus on sea level rise because you know a lot reasonable people think the U.N. wildly underestimated the upper end of the range and you want to attack Al Gore for worrying about 20 - foot sea level rise.On this blog, I have tried to be clear what I believe with my earlier three - part series: Since sea level, arctic ice, and most other climate change indicators have been changing faster than most IPCC models projected and since the IPCC neglects key amplifying carbon cycle feedbacks, the IPCC reports almost certainly underestimate future climate impacts.

In particular: i) the emphasis on reconstructions of historical temperature records; ii) the over-sensitivity of climate models; iii) the exaggeration of positive feedback mechanisms and the opposite with respect to negative feedbacks; iv) the over-statement of second and Nth - order effects of warming on natural processes and society as «impacts»; v) the IPCC reports are not written exclusively by scientists, but in the case of WGII and WGIII especially, are, as has been discovered — by sceptics — written by academics from other disciplines, often without any remarkable expertise, and by activists, with particular agendas.

Although it is reported that there are some relationships between the present states of cloud (e.g. Williams and Webb 2008, Yokohata et al. 2010) or water vapour (Sherwood et al. 2010) and climate feedback processes, it is not straightforward to relate the reliability of the present behavior and the climate sensitivity as discussed in Sect. 2.3.

The NIPCC report exaggerates the uncertainty in climate science, but seems to put a lot of faith in elusive and hardly quantified processes such as natural aerosol feedbacks coming to our rescue.

In its Arctic Climate Feedbacks: Global Implications Report, WWF says that the effects of the warming of the Arctic will be worse than previously prediced on everything from farming to forestry worldwide.

The model studies plus the theory of chemical feedbacks in the CH4 - CO-OH system (Prather, 1994) firmly established that the atmospheric lifetime of a perturbation (and hence climate impact and GWP) of CH4 emissions was about 50 % greater than reported in the FAR.

Is it or is it not that case that the author's of the IPCC reports have systematically conspired to silence intelligent climate science and the divine negative feedback theory?

Thinner snow cover may be the culprit, because it creates a feedback loop, Climate Central reports.
