Future Shorelines

Been way too busy with the book project (Ten Years That Shook the City: San Francisco 1968-1978) and a fascinating oral history project (“Ecology Emerges”) that has had me doing sixteen interviews in the past few weeks… sorry for my poor blog here, which has lost out in the tussle for my time… anyway, wah wah wah.

These are now available from me via my personal website... perfect for hanging on your bike as the oceans rise!

I’m planning to be in Copenhagen at the Climate Conference (not inside, but outside) in December, and along with a whole lot of other folks on the planet, I’m thinking more and more about the dire facts piling up… We’ll be riding this Saturday in San Francisco along one possible future shoreline, as part of the thousands of actions across the country clamoring for meaningful policy change on Climate Change. We’re hosting a Talk next Wednesday at CounterPULSE on “Climate Change/Climate Justice” and I hope a lot of folks will come out for it.

I’ve been expecting to see a major rise in ocean levels in my life time, in spite of the commonly cited figures of a meter rise by 2100 or even less. I think it’s all going a lot faster than anyone can measure, and the synergistic reactions among different factors, like melting ice sheets, thawing arctic tundra, etc., are coalescing into a perfect storm. Inundation of coastal areas seems like it could happen rather suddenly, like within 10-20 years. Here’s a piece I came upon today that drives it home with a bit more science:

And what of that lodestone, global sea level? This happens to be a very interesting question, because ocean levels are set to rise dramatically. According to UCLA scientists, the last time carbon dioxide levels were as high as they are today was 15 million years ago. At that time, the sea level was between 20 and 36 metres higher (75 to 120 feet), there was no permanent ice cap in the arctic, and very little ice in Antarctica or Greenland. That is where we are headed. The only remaining question is, How long will it take us to get there?

The authors of the Hadley Centre report predict a rise of just 1.4 metres by 2100. The IPCC in their 2007 4th Assessment Report predicted something like half a metre by 2100 based on a combination of the fattening of the oceanic envelope caused by thermal expansion and the increased runoff from glaciers and minor ice sheets. None of this sounds particularly catastrophic just yet, but then it turns out that these predictions are not based on anything particularly relevant: the British Antarctic Survey, in 2008, made it clear that the IPCC had not included the source of nearly 100% of the world’s potential ice melt ““ the major ice caps of Antarctica and Greenland ““ simply because they had little idea of how the ice caps would behave in a heating world:

The Intergovernmental Panel on Climate Change (IPCC) highlighted the issue by suggesting that current knowledge is inadequate to estimate confidently the contribution that ice sheets might make to sea-level rise in coming centuries. While technology makes sea-level rise easier to observe, and we can predict some contributions to future sea-level rise with increasing certainty, we cannot yet fully predict the ice sheets’ contribution. There is thus a risk that sea-level rise could be higher than the (incomplete) estimates provided by the IPCC.

Thus, the most peer-reviewed piece of climate science ever written turns out to be completely inadequate when it comes to estimating the level of disruption associated with a very important aspect of climate change: the rising seas. If Antarctica contains 90% of the world’s land ice (sea ice, like that in the Arctic, does not directly cause the oceans to rise when it melts) and Greenland contains most of the rest, then what’s going to happen when they start to melt with a vengeance, and when are they going to start melting? Official science is mute on the subject.

New Generation Meets Iconic Bicycle Messenger

I’m happy to welcome my media naranja, Adriana Camarena, as a guest blogger. This is her first but I hope not last contribution to The Nowtopian!

When I think of bicycles in Mexico beautiful images of workers spring to mind. Delivery men flutter on the streets on two or three wheels pollinating the neighborhoods with water, bread, telegrams, mail, newspapers, flowers, pharmacy errands, tacos de canasta, and other daily comforts. The factory workers also arrive on their bicycles. The films of the Golden Age of Mexican Cinema — often in the same category as cult Mexican films — nurtured the national imagination with an abundance of characters on bicycle. Pedro Infante -““ a legendary Mexican singer and actor of that era — in a biographical film about his life is depicted as a humble bicycle mechanic in his beginnings. Among my favorite cast of characters on bicycle is the knife sharpener. He blows a sharp whistle as he rides through the street, telling his clients that he is available. When I lived in Mexico City, many times I called out from my top window “I’ll be right out!” El Afilador de Cuchillos places his back wheel on a stand. He sits and peddles backwards on his bike to whirl the sharpening stone; sparks fly to give knives a new edge. For more than a century, such workers have peddled the streets of Mexico. Even in the most populated cities of Mexico, the flowers, the bread, the water, the news, the mail, still arrive on bicycle.

On Saturday, September 19th 2009, Chris and I wandered the pedestrian zones of the historical colonial center of Guadalajara during the lunch hour, here known as la hora de la comida or la hora de la siesta. La hora lasts about two hours. We spent the hour eating pistachio and prune ice paletas, while window shopping, buying a wooden spatula on the street, and people watching; I even tried on a sparkly Quinceañera crown made of silver and crystals because it was rather remarkable. In other words, we were making time before the afternoon conferences of the second day of the Second Annual National Cycling Conference. (I say making time, because while English speakers “kill time” whenever they have a surplus of time on their hand before an event, we Spanish speakers say we are haciendo tiempo: making time.)

While we wander around, making time, I see an elder gentleman with his bicycle in front of a pharmacy. I shamelessly ask him “Disculpe, señor, are you a messenger?” Messengers are on my mind. Later that afternoon, we will attend a conference delivered by a panel of bike messengers.

Well, this is my own purchase, right now”, he says pointing to a bag in the crate on the back of his bike, “But, I am a messenger in everyday life. “¦ Once upon a time, I delivered telegrams.”

We have a conversation, and part ways. Chris and I retrace our steps to the Museo de la Ciudad to attend the Bicycle Messenger Talk headed by bike messenger Jimmy Lazima from Los Angeles, California, one young bike messenger from Ciudad Guzman, Jalisco, and fixie bike aficionados from Guadalajara. Jimmy engages the audience with stories about riding and working through gridlocked Los Angeles streets. The Mexican messenger talks about his on-going and painstaking efforts to set-up business, create a clientele basis, and promote ecological culture in Ciudad Guzman without yet being able to make a living from his efforts.

Kafka Mexicana

Tag this one as fine whine…

Mexicana airlines is probably among the world’s worst. I’ve had my bad experiences with them in the past, but this trip to Guadalajara has reached a new depth. It all started back in April when I was invited to speak at the 2nd Annual Mexican Cycling Congress in Guadalajara. They kindly offered to cover my airfare, which was handled by a sponsor with lots of frequent flyer miles on Mexicana (their program is known as “Frecuenta”). I was excited since Adriana’s family is mostly in Guadalajara, so she made plans to join me, using some of her surplus of Frecuenta miles to cover her airfare. We had our flights arranged, flying down on the last day of April, going to the conference and then flying home about 10 days later from Mexico City where we planned to go overland…

That’s when the fun started. The Big Flu Scare caused the conference to be postponed, so the tickets were put on hold, pending the new dates. Eventually, after many calls, our friends in Guadalajara got my ticket rescheduled for this trip. The problem is, now we didn’t want to go Mexico City ten days later. We wanted to go home after a week in Guadalajara. The ticket was switched to the right dates, but there was no connecting flight between Guadalajara and Mexico City and we had to return from there! Adriana’s ticket was even more ridiculous because though she got on the same flight down (which itself is just awful–leaving SFO at 12:20 a.m. and arriving in Guadalajara at 6:15 a.m. or 4:15 a.m. for us! no sleep), but her return ticket was scheduled for the same original return date, May 12, but now in 2010!!

We ate SO well here! Mexican cuisine is among the best in the world, easily!

I spent over an hour going through Mexicana’s 800 number in the U.S. trying to rebook my flight to the U.S. direct from Guadalajara. I was told, after 3 different operators passed me along, that I was not able to do it. Only the original Frecuenta account holder could alter the ticket. So I asked the friends in Guadalajara to do it, and they weren’t able to either. We were quite puzzled. Adriana spent two entire afternoons, almost 6 hours, on the phone with various Mexicana operators, trying to change her flight (they were HER miles for her flight), but at first they wouldn’t even credit her with the original miles they’d “spent” on the May trip that got postponed! After many hours she was told her miles had been returned to her. Still she could not alter the return date of the trip! Nor could she change the itinerary to return directly from Guadalajara (though on the phone two different operators had indicated that we COULD change that).
