Planes or Volcano? | Information Is Beautiful (via @johngoldsby)
We were wondering this today.
UPDATE 1: A few people have asked so here’s how we estimated the CO2 emissions of Eyjafjallajoekull.
Data here: http://bit.ly/planevolcanoWe couldn’t find a direct CO2 emissions figure for the icelandic volcano but we did find an emissions figure for Sulphur Dioxide (SO2) – 3,000 tons a day (Source)
When Mount Pinatubo in the Philippines erupted in 1991, it emitted 42 million tons of CO2 (source) and 17 million tons of SO2 (source). That’s a CO2-to-SO2 ratio of 2.47:1
Applying that ratio to the 3,000 tons of SO2 emitted by Eyjafjallajoekull gives us the figure of 7,412 tons of CO2 per day.
Clearly, this is a ballpark figure and it’s likely to be more complex. If any vulcanologists are passing by and would like to enhance or correct our numbers, please help yourselves to the data!
UPDATE 2: We’ve been sent some new figures from the Nordic Volcanological Institute of the University of Iceland (thanks Nicole!). They’ve measured the CO2:SO2 ratio as 5:1 (source). So Eyjafjallajoekull is emitting an estimated 15,000 tons of CO2 a day – twice our original estimate. We’ve updated the diagram accordingly.

The MODIS instrument on NASA's Aqua satellite captured an Ash plume from Eyjafjallajokull Volcano over the North Atlantic at 13:20 UTC (9:20 a.m. EDT) on April 17, 2010.The Eyjafjallajokull volcano in Iceland erupted Wednesday, April 14, for the second time this month. The volcano is still spewing ash into the air and the ash clouds are impacting air travel in Northern Europe.

The Auto-Tune Meme (Video)
November 16, 2009
Much has been written about Auto-Tune in the mainstream media. Whether you love or hate the tool (and its effect), the public beyond recording engineers, producers and musicians has become hyper-aware of its use. And many people are starting to get annoyed.
A friend sent this video along this morning, and I thought those of you who find the T-Pain effect annoying might find this interesting. Though the video is humorous (and features "Weird Al" Yankovic--awesome!), it poses an interesting idea of where we are in the cycle of the Auto-Tune meme, referencing the history since Cher's release in 1998, and that we may soon reach a point of equilibrium. The effect will not go away, but rather be less overused and more balanced.
In the meantime, enjoy the video (5:52).
