Here's a tool that tries to connect the best available science directly to the international climate change negotiations and commitments, and the politicians are using it!
Perhaps that, in itself, is progress.
"How Does It Work? In the run-up to COP-15, we are scanning UNFCCC submissions and news sources from around the world to collect a list of what we call 'current proposals' — possible scenarios for greenhouse gas emissions by UNFCCC parties. We share our compilation and use the C-ROADS-CP climate simulation to calculate the expected long-term impacts (in terms of GHG concentration, temperature increase, and sea level rise) if those proposals were to be fully implemented."

But this year, I was also looking forward to some vacation time following the conference. Jerelyn and I took five days' of vacation after Greenbuild to explore southern Arizona and celebrate our 25th anniversary. As day transitions to night on the flight back east, I reflect on that time.
On Saturday morning, we traveled southeast from Phoenix, past Tucson, to the Hacienda Corona do Guevavi bed & breakfast in Nogales, Arizona, just a stone's throw from the Mexican border. The region is rich with wildlife and draws thousands of birders and others from throughout the world each year. Along with hundreds of bird species in the canyon oases sprinkled throughout Cochise Country (we saw about 60 species in our travels) are such exotic mammals as coati, ringtail, antelope jackrabbit, collared peccary (javalina), cougar (mountain lion), bobcat, and maybe (at least before the border fence) the rare cats ocelot and jaguar. Other than the antelope jackrabbit, we didn't see any others of those mammals, but it was great imagining them watching us from hidden spots rock ledges during our daily hikes.
On all of these hikes, at least when I wasn't trying to identify another new bird species, I spent time thinking about — and discussing with Jerelyn — the water crisis facing this region.
The press release says, "Yosemite black bears select minivan as 'Car of the Year'":
An article in the October 2009 issue of the Journal of Mammalogy examines the number of vehicles, by make and model, that black bears broke into from 2001 to 2007 in California's Yosemite National Park. In all years, minivans had the largest or second largest number of break-ins by bears.
Based on a survey of the types of vehicles visitors to the park drive, it was found that "only minivans were broken into at a rate higher than expected based on their availability."
According to the article, titled "Selective Foraging for Anthropogenic Resources by Black Bears: Minivans in Yosemite National Park":
Black bears forage selectively to balance energetic and nutritional gains with foraging costs. Selection of minivans by bears in Yosemite National Park was the likely consequence of efforts to maximize caloric gain and minimize costs by targeting vehicles with higher probabilities of payoff. Potential costs to bears came in the form of energy spent breaking into vehicles and considerable risk because park rangers were deployed nightly for surveillance and bears detected in or around campgrounds and parking lots received aggressive negative conditioning. The trade-off between food acquisition and penal actions by humans likely pressured bears to target vehicles with the highest probability of attaining food.
Cost-benefit analysis. Bears aren't so different from us.
I received an email from a Design student at Kingston University (London) writing a dissertation on "why people are drawn to design inspired by nature." Three questions were sent; I went overboard answering the first one, and basically wussed out on the second two. I'd be interested in your takes on this highly subjective stuff, and will be sure to let our dissertation author in on the discussion.
1. Why in your opinion are people so drawn to design inspired by nature?
2. What in your opinion is the finest example of design inspired by nature in the field of product and furniture design (my course)?
3. Do you think there are psychological benefits to design inspired by nature, and what do you think they are?
1. Why in your opinion are people so drawn to design inspired by nature?
I don't think everyone is drawn to design inspired by nature. Some like Le Corbusier's buildings at their boxiest, and contemporary glass and aluminum offices and homes, and Danish Modern furniture, while others like nature-inspired design... simply because they do. There's no accounting for taste. I know that speaks to the shallowest part of peoples' immediate and visceral reactions to aesthetics, but I think that most of the time — especially in this day and age — that's all there is to it. It's certainly not true of everyone, but most people in these harried times never have any need or desire to consider why some fashion appeals to them while some other fashion doesn't. It is what it is, and there are ten thousand other urgent things to attend to. If pressed, they'll tend to latch onto any available notions that support their position without actually considering them. Look to politics as an independent example of that. Trying to detangle rationalizations from pure impulse is a tricky business. (But it would probably be a much better world if more people tried.)

We need to continue these efforts to reduce greenhouse gas emissions and sequester carbon dioxide, but the reality is that it's too little, too late to prevent climate change. Even if the CO2 spigot were turned off tomorrow, the earth would still see significant warming and the other predicted impacts of climate change: more intense storms, flooding, drought, wildfire, and power interruptions. It's time to design our buildings and the built environment to adapt to the very different climate that scientists say is going to be with us.
That's the subject of the feature article in our September 2009 issue of Environmental Building News: "Design for Adaptation: Living in a Climate-Changing World" (requires log-in) (no login required — see Alex Wilson's note in the comments, below).
Andrea Ward and I interviewed some of the nation's top climate scientists, including Stephen Schneider, Ph.D., of Stanford, and Jonathan Overpeck, Ph.D., of the University of Arizona, to establish context for the article — making the case that not only is climate change happening, but it's happening more rapidly than the best climate models predicted just two years ago.
We address the question of mitigation vs. adaptation — whether we should put effort into preventing climate change or adapting to it — and argue that we must do both simultaneously. "The bottom line is that you've got to adapt to what won't get mitigated," says Schneider in the article.
Moving on, we focus on measures for adapting to climate change. We describe 36 strategies, organized into five categories, providing context for each of the categories and succinct explanation for each strategy. These strategies are listed briefly here (details appear in the full article):
As a follow-on to the previous post (Natural Building in the Shadow of the U.S. Capitol), the strawbale journal The Last Straw — which started publishing right around the same time as Environmental Building News — has expanded its web presence in a donation- and ad-supported bloggish setting at http://tls.buildearth.org.
A number of articles have been posted, including Earth Plastering Guidelines for Finishes, Figuring the Hidden Costs in Your Building Plans, Native to Place: Sustainable Design Can Forge Stronger Communities, Finishing Bale Walls with Siding, and more.
In what must be a marketing oversight, it's difficult to find a link from the blog to the journal's actual website.

In 2008, the USBG (that's the US Botanic Garden — not the USGBC) organized "One Planet — Ours!" to showcase sustainable techniques and technologies including things like edible school yards, urban orchards, a solar greenhouse, photovoltaic panels, residential wind turbines, green roofs, and rainwater harvesting. Part of the exhibition was a gorgeous little strawbale demonstration building (video link).
One of the results of that exhibition — besides the huge public exposure — was a Congressional briefing about straw bales as a building material.
Last winter (after the inauguration), the demonstration building was lifted in one 8-ton piece by crane and trucked to a new location where it now lives on as a studio. And there's video of that, too.
Even though you've missed the little strawbale house, there's more natural building on the next block. Always Becoming is an art installation on the grounds of the National Museum of the American Indian. "The five sculptures range in height from seven and a half to sixteen feet tall, and are made entirely of natural materials: dirt, sand, straw, clay stone, black locust wood, bamboo, grass, and yam vines." Here's some pictures I took while it was going up in 2007.
Men should pee sitting down.
Now before you call me a strident feminist, let me say that I'm backed up on this one by male colleagues and the reasons aren't what you think. I'm not arguing for toilet equality here.
I'm talking about urine-separating toilets, which are much easier to use for men and women when sitting down. The bowl of these toilets takes urine in the front, feces in the back. It's hard enough to aim for the whole bowl (or so the evidence of many bathroom floors tells me), much less the front part of the bowl. One guy put a pee can in the corner, but that seems inefficient: pee in the can, then pour it down the toilet. Why not just pee in the toilet?
Why should you care? Because urine contains up to 90% of the nitrogen and 50% of the phosphorous in domestic wastewater. Those chemicals make for great fertilizer — stuff we have to use a lot of energy to produce artificially. In healthy populations, urine is sterile, and removing it from feces makes composting the solids easier and more effective.
Two models of these toilets are available in the U.S., both from Ecovita. But before you rush out to buy one and change your life, remember that composting solids and using urine to irrigate your tomatoes isn't legal in most places. You might be able to get special dispensation from the building code folks, but like most things involving wastewater treatment alternatives, it won't be easy.
Watch for the coming article in the September issue of EBN.
