My birthday and International Day of Climate Action

Friday was my birthday, and to celebrate I went bowling with a few folks from the lab. Saturday was the 350.org International Day of Climate Action. 350 ppm is the maximum amount of CO2 in the atmosphere that is compatible with life on Earth as we know it, according to American climate expert Jim Hansen. The idea is for people around the world to create elaborate displays of the number 350 and take pictures, which are distributed throughout the media. Hopefully those pictures will convince world leaders attending the climate conference in Copenhagen in December to agree on a powerful carbon tax.

An article in the New York Times mentioned that 350 ppm is an impossible goal to achieve, and so by publicizing 350 this movement is actually telling people that we've already blown it, so might as well enjoy life while we can. I think this is a valid point, but on the other hand the role of the 350 number was mostly to create a common rallying call for people who speak many different languages and provide a simple symbol of the climate change movement. The actual numerical value of 350 is not as important as what it symbolizes: a coordinated and passionate movement among people of all cultures on earth demanding action from world leaders to avoid catastrophic climate change.

I started Saturday by participating in a human thermometer on Baldwin Street to depict 350 ppm CO2. Somewhere between 50 and 100 people showed up for this morning event. Then I rode into town to the Dunedin train station, the site of the 350 food festival. I had only a few minutes to do a preliminary walk-around before the 350 riders bike ride began. We rode about 5k out to the Vauxhall boat club, snapped a few pictures with all the riders arranged in a 350, and then rode back to the food festival. There were hundreds of riders participating.

The food festival was similar to the usual Dunedin Farmer's Market, except there were additional workshops and a live band. I attended a workshop on beekeeping. At midday hundreds of people gathered in the garden in front of the train station for a photo taken by a guy in the bucket of a fire truck.

Here's a link to pictures on the 350 website. And here are a few I got myself.
