Will the vanity of centrists doom us to climate disaster?
Knee-jerk moderation is not the same thing as sensible risk management
Since the release of the new IPCC report on the current and future effects of climate change, climate hawks (including myself) have made the same very basic argument that we always do: Climate change looks bad, potentially very bad, and therefore we should curtail the greenhouse gas emissions which cause it.
Clive Crook writes that this is approach is somehow responsible for public skepticism of climate change:
As I'll explain in detail below, Crook is completely, 100 percent wrong with his description of the new report. But his basic attitude reveals a deeper mistake which is unfortunately incredibly common.

First, the details. Crook asserts that the new WGII report is more carefully hedged and doesn't predict catastrophe — that it is less alarming than its predecessors. This is simply false. Compare this summary for policymakers to its predecessor from 2007: The new one is much more confident about its attribution of current negative effects, and if anything more blunt about future risks.
Then he all but accuses Secretary of State Kerry of lying, asserting that the IPCC doesn't predict catastrophe from unchecked climate change. To which I can only say, did he even read the report? (If past history is any guide, probably not.) Here are some handy excerpts from page 12 of the summary, all identified with high confidence:
I don't know what definition of catastrophe doesn't include that lot. But I'd think, at a minimum, he owes Kerry a detailed explanation as to why not. Remember Clive, page 12.
This lack of detail brings me to Crook's most serious mistake:
The striking thing about this tone of high-minded, serious moderation is that it contains no engagement with the evidence whatsoever. So if the greens are wrong about the dangers of climate change, how much warming is acceptable? Is the international consensus that two degrees Celsius is the maximum allowable wrong? If so, why?
He doesn't even begin to answer these questions.
Here's the nickel summary of the climate hawk case: According to the IPCC, to keep warming under two degrees Celsius, human society can emit roughly one trillion metric tons of carbon. As of 2011, we have emitted 531 billion tons, leaving 469 billion tons remaining to stay under the one trillion ton cap. Several years have since passed, and we are releasing roughly 10 billion metric tons per year, which is increasing — meaning on our current path we will blow through the cap by 2040.
You can dive in to the details here, but given the rough magnitudes of those numbers it is very easy to understand the case intuitively: To stay under two degrees of warming, we must sharply reduce our emissions very soon. The longer we procrastinate, the steeper the drop must be to stay under two degrees.
Even just stabilizing our emissions now and cutting them at a rate unprecedented in human history is totally inadequate. If we peak in 2015 — which, in case you've forgotten, is next year — then rich countries will probably have to cut their emissions by roughly 10 percent per year, an utterly unprecedented amount. And remember, this IPCC report barely even considers levels of warming of four degrees Celsius or higher. Studies on that kind of thing are truly the stuff of nightmares.
If you believe in the risks of climate change, as Crook claims he does, then that's the reasoning that really matters: How much greenhouse gas is being emitted, and how much we can emit overall. That leads directly, using nothing more than simple arithmetic, to a rough calculation of how fast emissions must be cut.
This is the problem with Crook's brand of High Broderist faux-moderation. Crook says he supports some kind of carbon tax and public funding for research and mitigation, but he quite obviously hasn't given the slightest thought as to whether that policy would be enough to achieve his climate goals, or even what those goals are. Instead, he just implicitly assumes that the best solution is one that doesn't disrupt the status quo very much.
Any position called "moderate" with respect to climate science would, at a minimum, engage with the evidence and predictions, which leads straightforwardly to a need for extremely aggressive action as soon as possible. But Crook's position is political moderation — that is, simply picking a point somewhere in the middle of the political spectrum.
Political moderation on climate change is many things, but perhaps the most important one is that, as we've seen, it is incredibly risky. Such a position is, in effect, courting tremendous damage to human civilization to avoid admitting that the greens might be right about something.
