Greased lightning

Here's an interesting biodiesel stat:

[T]he region's supply of fryer grease is limited. Each Oregonian contributes about a gallon of used cooking oil a year to the grease market. [Emphasis added.]

That's really not much grease -- especially considering that Oregon residents consume about a gallon and a half of highway fuels per person each day. So as much as I love biodiesel, fryer grease just isn't going to power rush hour.

The debate on plug-ins begins

Alan Durning's article makes a lot of good points about the need to do more than just improve the efficiency of our personal transport. It's a great article, but it also contains a few inaccuracies that I feel obligated to clear up before the global warming deniers (among others) try to use them.

I can tell from the comments on Alan's post that some readers are under the mistaken impression that his conclusions are a reflection of the EPRI/NRDC (PDF) report cited, but many are actually counter to that report. For example:

Latest IPCC climate report comes out strong, lays groundwork for Bali talks

“Warming of the climate system is unequivocal,” warned the Nobel Prize-winning Intergovernmental Panel on Climate Change in its hardest-hitting report yet, released on Saturday. Delegates from more than 140 countries came to agreement on the document, which summarizes three previous reports and warns of the grave dangers posed by climate change. The new report is […]

Contents of the IPCC Sythesis Report Summary for Policymakers

For those not familiar with it, the Intergovernmental Panel on Climate Change was set up in 1988 to write periodic assessments of the state of climate science. Its goal is to produce policy-neutral reports that inform policymakers about the best thinking of the scientific community. These reports have tremendous impact on the debate, owing to the credibility of the IPCC process.

The IPCC is actually split into three working groups. Working group 1 focuses on basic climate science, working group 2 focuses on the impacts of climate change and human adaptation to it, and working group 3 focuses on mitigation efforts (efforts to reduce carbon dioxide emissions). In 2007, as part of the IPCC's fourth assessment report, each of the three working groups issued a report (e.g., see here for a discussion of the working group 1 report).

Now comes the final part of the fourth assessment report: the synthesis report. This report ties together the three working group reports in an effort to create a single unified picture of what we know about climate change.

IPCC says debate over, further delay fatal, action not costly

In its definitive scientific synthesis report (PDF), the Intergovernmental Panel on Climate Change (IPCC) today issued its strongest call for immediate action to save humanity from the deadly consequences of unrestrained greenhouse gas emissions.

This report -- signed off by 130 nations including the U.S. and China -- slams the door on any argument for delay and makes clear we must under no circumstances listen to those who urge that we wait (who knows how long) to develop as yet non-existent technology [this means you President Bush, Newt Gingrich, Bjorn Lomborg]. As The New York Times put it:

Members of the panel said their review of the data led them to conclude as a group and individually that reductions in greenhouse gasses had to start immediately to avert a global climate disaster that could leave island states submerged and abandoned, African crop yields decreased by 50 percent, and cause over a 5 percent decrease in global gross domestic product.

... this summary was the first to acknowledge that the melting of the Greenland ice sheet from rising temperature [which would raise the oceans 23 feet] could result in sea-level rise over centuries rather than millennia.

Readers of this blog know the IPCC almost certainly underestimates the timing and severity of likely impacts because it ignores or downplays key amplifying feedbacks in the carbon cycle (see "Are scientists overestimating or underestimating climate change," especially Part II and Part III). Indeed, IPCC head Rajendra Pachauri -- a scientist and economist -- admitted as much:

He said that since the panel began its work five years ago, scientists have recorded "much stronger trends in climate change," like a recent melting of polar ice that had not been predicted. "That means you better start with intervention much earlier."

How much earlier? The normally understated Pachauri warns:

"If there's no action before 2012, that's too late. What we do in the next two to three years will determine our future. This is the defining moment."

In short: time's up! America, we better pick the right President in 2008.

To balance the bad news, the IPCC and its member governments agree on the good news -- action is affordable:

IPCC synthesis report confirms global warming is a force to be reckoned with

And now, ladies and gents, the moment you’ve all been waiting for. The Nobel Prize-winning Intergovernmental Panel on Climate Change, with input from delegates of more than 140 countries, has synthesized three previous reports into one 70-page summary document and a 20-page summary of that summary, meant to be an “instant guide” to policymakers who […]

Giving up car-lessness for Rob Lowe’s plug-in hybrid

This essay is part of a series on not owning a car.

-----

The weekend before Halloween, my car-less family got a loaner plug-in hybrid-electric car to try. You see, the City of Seattle and some other local public agencies are testing the conversion of some existing hybrids to plug-ins to accelerate the spread of these near-zero-emissions vehicles. As a favor and, perhaps, for some publicity (this post), the city's program manager offered me four days' use of the prototype -- previously driven by actor Rob Lowe.

Enthusiasm about plug-in hybrids -- like their now-almost-mainstream siblings the gas-electric hybrids -- has been running high of late. For example, the California Air Resources Board is among the toughest air quality regulators in the world. When members of the board's expert panel reviewed the evidence on plug-in hybrids, they issued a boosterish report predicting widespread adoption and fast market penetration. The Western Governors' Association is similarly smitten (MS Word doc). The tone of some popular press reports makes it seem that the vehicular second coming may be at hand.

For this auto (pictured in our back yard, with our Flexcar visible out front), I wondered, would my family give up its car-less ways? Would the joy of these 100+ mpg wheels cause us to end our 21 months of car-free-ness, emulate Rob, and buy our own plug-in?

The short answer? No. Plug-in hybrid-electric cars hold great promise, as long as we can fix the laws. And the technology. Oh, and the price.

None of those fixes are "gimmes." Without fixing the laws -- and specifically, without a legal cap on greenhouse gases -- plug-ins could actually do more harm than good. And without the second two fixes -- working technology and competitive prices -- plug-ins won't spread beyond the Hollywood set. (Echoes of this point are in Elizabeth Kolbert's latest article in The New Yorker.)

But I'm getting ahead of myself. Let me start at the beginning.

L.A. bereft of clouds, rain; climate change the culprit?

I arrived in L.A. yesterday in the midst of an unusual meteorological phenomenon. The sky seems to have been wiped out, replaced entirely with a deep, featureless expanse of turquoise blue. And that’s not the weirdest part. All day long, a strong, bright light was falling from the sky on inhabitants, as though we were […]

IPCC Synthesis Report coming out Saturday

Policymakers of the world, get ready. Tomorrow, the Intergovernmental Panel on Climate Change releases its Synthesis Report that will attempt to summarize the world’s climate-y plight in a language governments can understand. Saturday’s report will be the official abbreviated version of the 2,500 pages of scientific reports the IPCC churned out earlier this year. The […]
