Three climate negotiators walk into a bar …

Analogies can be dangerous when you don’t know their limitations, but they can be a good way of distilling a lot of technical details into a central point. A flurry of emails last week resulted in this story at Climate Interactive, about some inebriated decision makers who can’t predict the consequences of their actions. It reminds me of another favorite, cited in Cloudy Skies:

The article gives a fascinating insight into the way international politics struggles with complex technical issues. I was inspired to set up an experiment to test some of the ideas, and hit upon the analogy of using my bath instead of the Earth and taking the water as carbon dioxide. I jammed the plug firmly, and turned one tap to full. I observed that the bath was filling with water. I turned the flow down to 80% – a massive 20% reduction – only to discover that it was still filling but slightly more slowly. At this point I was joined by my neighbour, an American. He pointed out that reducing the flow by 20% was out of the question; we haggled for a bit before agreeing on a reduction to 94.8%. We thought the 5.2% reduction had a nice ring to it. Oddly, the bath was still filling up with water at almost the same rate that it had been initially. My friend then gave me a five pound note to turn the tap down by another 20%. I did so. He then turned on the other tap to exactly counter the 20% saving. I complained, only to be told that he had bought my credits, whatever that means. He then rushed out, returning with a bucket which he put under the second tap. I was so impressed that I did not notice for a moment that the bath was still filling up and that the bucket would soon overflow. We decided we had experimented enough for one day and went off to the pub. We were on our third pint when we remembered that the experiment was still running.

Letter to The Chemical Engineer from A. Lodge (1999)

Unfortunately, even in simple systems, intuition often deserts us. The fact that mental models fail to capture the essence of climate dynamics is but one symptom of this. This Thursday, Drew Jones and I will present a simple model designed to close the gap at the Tällberg Forum’s Washington Conversation, “the climate deal we need.”

Inflection Point Oil

Peak oil gets all the attention, but the peak isn’t the problem. Unless your assumptions about the dynamics of oil production are rather artificial, there will be an inflection point before the peak. Symptoms of strain in the system appear as soon as the production rate grows more slowly more slowly than GDP less intensity improvements, or simply more slowly than expected. That’s when price has to begin rising to clear the market, creating the signal to alternatives (efficiency, biofuels, unconventional oil …) that they are needed, so that’s when the pain hits. Whether the pain is brief and results in an orderly transition, or something rockier, is a matter for some debate. Either way, arguing about when the peak might come is the wrong question; we should be considering whether we’re past the inflection point, and thus in a period of rising stress, and what to do about it.

Jay Forrester honored in POMS

Production and Operations Management 17(4) honors Jay Forrester as an important person in the history of operations management. He joins Kenneth Arrow, Ronald Coase, and William Cooper in the distinction this year. Congratulations Jay!

Hat tip to John Sterman on the SD email list. I don’t have fulltext access to the journal, but if someone sends me a snippet, I’ll post it.

WCI Design Recommendations

Yesterday the WCI announced its design recommendations.

Update 9/26: WorldChanging has another take on the WCI here.
I haven’t read the whole thing, but here’s my initial impression based on the executive summary:

Scope

Major gases, including CO2, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride.

What? In scope? How/where?
Large Industrial & Commercial, >25,000 MTCO2eq/yr

Combustion Emissions

Yes Point of emission

Process Emissions

Yes Point of emission
Electricity Yes “First Jurisdictional Deliverer” – includes power generated outside WCI
Small Industrial, Commercial, Residential Second Compliance Period (2015-2017) Upstream (“where fuels enter commerce in the WCI Partner jurisdictions, generally at a distributor. The precise point is TBD and may vary by jurisdiction”)
Transportation

Gasoline & Diesel

Second Compliance Period (2015-2017) Upstream (“where fuels enter commerce in the WCI Partner jurisdictions, generally at a terminal rack, final blender, or distributor. The precise point is TBD and may vary by jurisdiction”)

Biofuel combustion

No
Biofuel & fossil fuel upstream To be determined ?
Biomass combustion No, if determined to be carbon neutral  
Agriculture & Forestry No  

(See an earlier Midwestern Accord matrix here.)

Bailout without Representation

The NYT has the draft text and an explanation of the Bush administration’s $700 billion bailout proposal. It audaciously creates a budget authority almost as big as the federal government’s total discretionary spending and bigger than every on-budget agency, seven times the California state budget, without any checks and balances at all:

Sec. 8. Review.

Decisions by the Secretary pursuant to the authority of this Act are non-reviewable and committed to agency discretion, and may not be reviewed by any court of law or any administrative agency.

We used to dump tea in harbors for things like this.

Backing Off on Ethanol

ST. PAUL (Reuters) –

U.S. Republicans called on Monday for an end to a controversial requirement that gasoline contain a set amount of ethanol, a policy backed by the Bush administration that critics say has helped drive up world food prices.

In their 2008 platform detailing policy positions, Republicans said markets — not government — should determine how much ethanol is blended into gasoline, and pushed for development of a cellulosic version, which could be made from grasses rather than corn.

It will be interesting to see what this implies for California’s LCFS design.

Update

Corn belt Republicans are not pleased.

Contrast the new platform with the situation in 2005.

McCain seems to have done a double-flip-flop, reversing his 2006 reversal of his 2000 campaign position: Continue reading “Backing Off on Ethanol”

Better Get a Bucket

Nature News and Climate Feedback report that cooling of sea surface temperatures ca. 1945 is an artifact of changes in measurement technology. ClimateAudit claims priority. Lucia comments.

Will this – like the satellite temperature trend – be another case of model-data discrepancies resolved in favor of the models?

Update: Prometheus wonders if this changes IPCC conclusions.
