Earth Day and Auctions

Here’s a half-baked post that I started months ago. I decided to rush it to press for Earth Day, which is today.

The first U.S. auction for carbon emission pollution rights occurred in December of 2008. It raised over $38.5B, which will go to six states in New England. From ScienceNOW Daily News:

The auction’s premise is that putting a price tag on pollution–so-called carbon trading–will eventually reduce emissions industrywide. Companies must pay for the right to emit greenhouse gas emissions and are penalized for excess pollution.

The ten states shown in dark green are participating in RGGI. Observers are represented in lime green.

How did the auction work? online, reserve price, open to investors and environmental groups, required for power companies in RGGI states. Not required for manufacturing or transportation. Any earth-day-interested readers out there to fill in these details? Or, to do a little follow up research about how things have gone? (I wrote this last December.)

Finally, here is a humorous critique of carbon trading, based on the observation that carbon credits are a scarce resource. This is highlighted by a paired example from cheatneutral. I find it compelling.

California foreclosures, mosquitoes, and skate punks

Do you remember last summer’s health scare around the housing market collapse? There was a theory that all the swimming pools in all the foreclosed houses in California would become major mosquito breeding grounds, leading to major crops of mosquitoes, leading to West Nile virus or maybe even the reintroduction of malaria in the US.

There have been some fun ideas for tackling this potential problem, like filling the foreclosed pools with exotic fish. But I woke up today to learn about my new all-time favorite approach: let skateboarder to drain the pools and skate in them. (thx @omarkhalifa)

Bonus points opportunity for my influential readers: WSJ reports that local disease control agencies are doing aerial surveillance for abandoned pools. Can you convince them to release their aerial photos of abandoned pool locations to the local skaters?

@healthyalgo is twittering

I guess I’m one to follow the latest fads. I have a blog, right?

I held off even considering “Twitter” for a long time, however. Who cares what I’m doing, right now, in 140 characters?

But that’s not actually what twitter is about (at least its not all that twitter is about). It’s more like having an IRC chat room, but in a public park. But the fauna is synthetic.

Anyway, I’m giving it a try. You can see how it’s going for me here.

My ego does depend a little bit on how many “followers” I have, but I’ve got practice dealing with this. When I was a college radio deejay, I usually had no idea if anyone was listening out there in radio land, so I’d put on my most depressive college radio voice, get on the mic and ask for callers. Then while I waited to see if anyone would call in, I’d dedicate this song to myself:

Welcome to National Public Health Week

Since 1995, presidential decree has designated the first full week of April to be National Public Health Week in the United States. The American Public Health Association is kicking things off with an online “viral video” campaign. Public health has much more experience trying to stop the spread of viruses, so this campaign has some underdog appeal. It’s also got nice motion graphics, but definitely not my first choice for inspirational music.

(Hey, this soundtrack would be so easy to remix, if only it had an appropriate Creative Commons license. APHA could probably get a bit of notice from folks who wouldn’t otherwise see a public health video by changing the license today and send CC and friends a nice press release. Hint hint.)

Matching Algorithms and Reproductive Health: Part 0

One of the first things on Obama’s agenda after being sworn in as President last week was lifting the “global gag rule”, a Regan-era innovation that tied US aid to strict anti-choice regulations. Meanwhile, the TCS reading group at UW has been studying matching problems and Edmond’s blossom algorithm. Together, this has been the motivation I needed to launch a series of posts about applications of matchings in reproductive health metrics. Part 1 will have more about matchings.

Harvey Milk, Mathematician

Movie I sawI had time to see a movie on Christmas day! And it turned out to be a great movie, Milk, with great acting by Sean Penn and many others. It is a true story of the first openly gay politician elected to public office in California.

It was mentioned only in passing in the movie, but it turns out that Harvey Milk was a mathematician. He wasn’t publishing research papers or teaching calculus classes as an academic professor, but, as he mentions in the movie, before getting into politics, he worked in insurance. Wikipedia has a little more to say about this: Milk was a “actuarial statistician”, and after that, but before becoming a political organizer,

Milk abruptly stopped working as an insurance salesman and became a researcher at the Wall Street firm Bache & Company. He was frequently promoted despite his tendency to offend the older members of the firm by ignoring their advice…

Milk was a quant! Any quants looking for a change of pace, Milk is an inspiring example of what a person did in 8 years, without doing a bit of activism before turning 40. I came across this youtube video of a speech Milk gave, that has some music mixed under it and motion graphics layered on top.

Holiday Viewing

It’s been snowing in Seattle for a week now, and that never happens. Things were already getting quiet around here for the holidays, but now there are almost no cars on the roads and it’s been really quiet. I’ve been watching healthy algorithm videos to pass the nice, quiet time:


Gaussian Process Basics
David MacKay


GP Covariance Functions
Carl Edward Rasmussen


Unnatural Causes
California Newsreel


The Trap
Adam Curtis
