It is quite strange that this paper seems to review future of tropical rainforest in the face of rising CO2 and rising temperature — unfortunately, it completely lacks to
mention change in precipitation, which is just - another - very - important (
climate change) metric — and it completely fails to
mention modelling work of Peter Cox group — that predicts decline in rain forest productivity and growth due to decline in precipitation..
Hence, we feel that the most important result of the study of Stainforth et al. is that by far most of the
models had
climate sensitivities between 2ºC and 4ºC, giving additional support to the widely accepted range (Update: As
mentioned in the follow up post, this clustering is mainly a function of the sensitivity of the original
model and the random nature of the perturbations).

1) Regarding the 1970s shift, Ray

Other studies of the Amazon
climate tipping point The existence of an Amazonian

Before discussing this, a methodological point affecting estimates of S needs to be
mentioned: results from methods estimating a PDF of
climate sensitivity depend strongly on their assumptions of a prior distribution from which
climate models with different S are sampled [Frame 2005].
The conviction that
climate model outputs are credible predictions for the future propagates beyond IPCC texts, often without
mentioning their origin (for which we can not imagine anything else but
climate models).
Curiously, this time around he doesn't
mention that the
models not only disagree with each other but also don't reproduce the
climate observed today.
As
mentioned there, I have Ph.D. in natural resource management (forestry,
modeling, ecology) and now have 149 publications — this means I can tell the difference between the usual case and anything I submit related to
climate change.
Your adoring reference to complex
climate models makes we wonder of you are aware of their staggering weaknesses, or are just choosing not to
mention them.
Other honourable
mentions in the Carbon Brief survey of most influential
climate papers go to Norman Phillips, whose 1956 paper described the first general circulation
model, William Nordhaus's 1991 paperon the economics of the greenhouse effect, and a paper by Camile Parmesan and Gary Yohe in 2003, considered by many to provide the first formal attribution of
climate change impacts on animal and plant species.
As you
mention, the response to CO2 is logarithmic, and this is the basis for almost all
modeling of CO2 / temperature relationships as well as estimates of past CO2 contributions to
climate change.
I have not gone through the list to see if Steel is correct, but none of the articles
mentioned deal with recent
climate change or
climate models.
The second and more interesting (to me) observation is that the simulated temperature changes are punctuated by multiple short term peaks and dips, differing from one
model run to another, although the
climate variables
mentioned above were omitted from the simulations — there were no changes in
model input in solar or aerosol forcing, and ENSO was largely eliminated by smoothing.
A point I've not seen
mentioned anywhere yet is that if Anthony Watts» paper is accepted then it blows a massive hole in the regional
modelling of the US and hence the global
modelling of
climate, because the
models have to hindcast as well as forcast.
Shouldn't you
mention the increasing number of OBSERVATIONS that appear inconsistent with the output of
climate models (assuming you think any are credible).
«The recent dramatic cooling of the average heat content of the upper oceans, and thus a significant negative radiative imbalance of the
climate system for at least a two year period, that was mentioned in the Climate Science weblog posting of July 27, 2006, should be a wake - up call to the climate community that the focus on predictive modeling as the framework to communicate to policymakers on climate policy has serious issues as to its ability to accurately predict the behavior of the climate

If systematic errors in their
model global
climate can be shown, that would indicate a problem, but none have been specifically
mentioned by David Young or others, so it makes it hard to answer except in general terms, like validation with plenty of global data has been done on GCMs.
Accurately
modeling precipitation in a geographically and topographically complex region like California can be tricky, and none of the studies I've
mentioned in this article explicitly link the extremely low 2013 - 2014 precipitation in California to
climate change.
There has been no attempt to propagate uncertainty through the FUND, DICE and PAGE

To summarize, both the

Our 2015 study examines the impact of 21st - century projected

Dr. Curry, Surely it would seem, a priori, that since
climate modeling treats a different regime of fluid dynamics
modeling than these you
mention — with different assumptions, scales, and approximations — it is quite possible that there are problems with certain types of
climate models without invalidating «all gas phase fluid dynamics
modelling».
Especially now with
climate models finally starting to include the EUV relationship to stratospheric effects, how can the solar effects not be
