Thanks for your comment.

Yes indeed I wrote that statement, and I stand by it. You can read it in context here:

http://sciencepolicy.colorado.edu/prometheus/archives/climate_change/000903is_ipcc_ar4_an_advoc.html

In his article Mr. Pearce labels me a climate skeptic. This is indeed wrong.

See this post:

Thanks!

I fear you are not your own best advocate. (Not that one should be surprised. Some top negoiators says that they don’t negoiate their own speaking and writing deals.)

I am a reader but I don’t know that “Mr. Pearce is just wrong”. Unfortunately, the best rebutal you have offered so far of Mr. Pearce is buried in these comments. But you haven’t addressed the factual question of whether you ever wrote or spoke such words about the IPCC? Or about anyone?

But regarding the quote: “seeing their role as political advocates rather than honest brokers”. Did you ever write or say such a thing in regard to the IPCC? It’s seems very likely that you wrote such a phrase about some topic at some time. I would think that the phrase might be found somewhere in your forthcoming book.

With Google I searched on the phrase in the quote and found only this blog.

I would note that making attibutions about what motivates someone else or “how they see their role” tends NOT to be your style. I applaud all those who avoid what I call the “attribution game” — making attributions of motivations and core beliefs without solid grounds for doing so.

Thanks for your comments. A few replies.

1. I find this game of trying to find some way to characterize me as a “skeptic” humorous, but I’ll play along. Please note that everyone who has policy preferences (i.e., all of us) are “skeptical” of those policies which we do not prefer. So we are all “skeptics” of something. Make no mistake, the effort to tar people with the skeptic lable on climate change is of a political strategy. Once you can label someone, it makes it far easier to dismiss the substance of their views. But if must give me a label, how about “Non-Skeptic Heretic”?

2. To characterize one end point in your spectrum, you write, “RPJr endorses the need to stabilize GHG concentrations at some level.” This statement is content-free, as ANY emissions path will stabilize GHG concentrations at “some level.”

3. At the other end of the spectrum, based on my post . . .

http://sciencepolicy.colorado.edu/prometheus/archives/climate_change/000923the_dismal_prospects.html

. . . you conclude that “RPJr opposes policies for stabilization at a doubling or less”

First, let me address your logic. My post was focused on handicapping the prospects for achieving stabilization at 550 ppm, which I find dismal (as, I should note, did the Stern Committee). This is not the same thing as advocating that we stabilize (or not) at 550 ppm. I might think that the weather will be fair and mild in Boulder this week, but it doesn’t mean that I am against snow.

4. More generally, I simply reject your spectrum as an ineffective way to frame the challenge of climate change — based on stabilizing atmospheric concentrations, a single approach (of many possible approaches) to the challenge of emissions reductions. I reject your framing for several reasons.

First, you are trying to frame the problem focused on “tuning” atmospheric GHG concentrations to some desirable level. Dan Sarewitz and I critiqued this particular framing in 2000 in this paper:

Sarewitz, D. and R. A. Pielke, Jr., 2000. Breaking the Global-Warming Gridlock. The Atlantic Monthly, 286(1), 55-64.
http://sciencepolicy.colorado.edu/admin/publication_files/resource-69-2000.18.pdf

Imagine if we were talking about poverty instead of climate change. Lets say that you proposed that we “stabilize” global poverty at no more than 5% of global population by 2075. And lets say I responded to you by saying that establishing such a target and timetable makes little sense from the standpoint of actually taking actions to reduce poverty. Would than make me a “poverty-reduction skeptic”?

No. It would mean that I favor policies that are (in my view) likely to be far more effective than the target and timetable approach to poverty reduction. Your (hypothetically in this thought experiment, of course) support for a target and timetable approach, doubting my favored policy, would thus make you the “skeptic” of my views. No?

In all of this, keep in mind that stabilizing greenhouse gas concentrations is a means, not an end.

5. I think that there are far better policy options on climate change than the targets and timetables approach. My views are supported by a large literature and now, years of experience under the FCCC and Kyoto. For example,

My own systhesis on how we might begin to reconstruct a climate policy that works on both adaptation and mitigation can be found in the following two papers:

Pielke, Jr., R.A., 2005. Misdefining ‘‘climate change’’: consequences for science and action, Environmental Science & Policy, Vol. 8, pp. 548-561.

http://sciencepolicy.colorado.edu/admin/publication_files/resource-2466-2006.09.pdf

[I won't have sympathy for responses that this is too much reading. The Stern Report is700 pp.;-)]

Are you skeptical of the policy proposals put forth in these various works? Does this make you a “skeptic of policies that might actually work”?

And if you are skeptical of policies that might actually work, is ist possible that you are in cahoots with Exxon and Senator Inhofe?

Are the true climate skpetics those favoring the current targets and timetables approach, because it is the option most likely to fail?

Hmmmmm . . .

OK, this last bit is obviously tongue-in-cheek, but the general point is that we ought to be able to have a debate about policy options on their merits without the reflexive urge to place each other into pejorative political categories.

Sorry for the length of this response.

Thanks to anyone who made it to the bottom!

(1) RPJr endorses the need to stabilize GHG concentrations at some level (based on the quote above from the disaster workshop which says emissions reductions are needed to avoid levels that could risk abrupt climate changes).

(2) RPJr opposes policies for stabilization at a doubling or less (based on your post in September on “The Dismal Prospects for Stabilization”, where you concluded that “stabilization at 550 is not in the cards”)

(whether you hold this position or not, this seems like a potentially untenable position if 550 ppm is sufficient, as some scientists believe, to induce abrupt climate changes)

As you have discussed, keeping concentrations to no more than a doubling is a widely stated goal among those who believe significant mitigation is needed (climate scientists and policy people alike). Is it fair, then, to say that you are a skeptic of this particular benchmark policy?

Best,
Scott

Thanks for commenting, but you completely miss the mark when trying to characterize my views. Below are a few statements that I’ve published in 2006 alone on mitigation. If you want to understand my views, have a look at my testimony this past summer at the House Government Reform Committee which provide the most concise and comprehensive perspective.

There is really no excuse for anyone to mischaracterize my views, they are all laid out in many publications and frequently here on this blog. So I do appreciate your asking rather than just assuming!

“Human-caused climate change is real and requires attention by policy makers to both mitigation and adaptation – but there is no quick fix; the issue will be with us for decades and longer. Nothing in this testimony should be interpreted as contradicting the assessment of climate change science provided by Working Group I of the Intergovernmental Panel on Climate Change (IPCC). The IPCC has concluded that greenhouse gas emissions resulting from human activity are an important driver of changes in climate. And on this basis alone I am personally convinced that it makes sense to take action to limit greenhouse gas emissions.”

http://sciencepolicy.colorado.edu/admin/publication_files/resource-2466-2006.09.pdf

“Mitigation of GHG emissions should also play a central role in response to anthropogenic climate change . . . Emission reductions are necessary to reduce the risk to reach levels of CO2 concentrations which might lead to abrupt climate changes and/or processes in the atmosphere which could become irreversible.”

http://sciencepolicy.colorado.edu/sparc/research/projects/extreme_events/munich_workshop/summary_report.pdf

“To emphasize, humans have an effect on the global climate system and reducing greenhouse-gas emissions makes good sense.”

http://sciencepolicy.colorado.edu/admin/publication_files/resource-2449-2006.02.pdf

(1) my impression, as a scientist doing climate-related research, is that there is a strong consensus that, in the words of a National Academy of Sciences report, “The changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability.” (Climate Change Science, 2001).

(2) The IPCC TAR Summary for Policy Makers (SPM) accurately represents this scientific consensus. In fact some of the most knowledgable and respected climate scientists are authors of the SPM, and they support this finding.

One’s position on the wisdom of mitigation must flow from a judgement of how the costs of mitigation are balanced against the benefits from climate change damages avoided by mitigation. Thus, one can oppose mitigation without questioning the science indicating that humans have caused the climate to change and are expected to cause it to change much more in the future.

Is that a fair characterization of your position?

Best,
Scott

At the end of the WG1 Chapter 4 Executive Summary: “Feedbacks between atmospheric chemistry, climate, and the biosphere were not developed to the stage that they could be included in the projected numbers here. Failure to include such coupling is likely to lead to systematic errors and may substantially alter the projected increases in the major greenhouse gases”

Or, from Chapter 7 Executive Summary: “significant deficiencies in ocean models remain.”

I certainly agree with the Executive Summary of Chapter 14:
