It’s a big day for climate news:

  • Just for the record, I’m a bit annoyed by this predictable critique of all of the fuel-guzzling limos crowding the Copenhagen streets during the talks.  Sure, the optics of limos at a climate conference are bad.  But focusing on appearances, and more generally on personal choices, is exactly the wrong way to think about climate change. If all the celebrities, dignitaries, and heads of state had decided to bike the streets of Copenhagen for the next two weeks, the net effect on global emission would be essentially zippo.  The real measure of success is the substance of the talks, not the carbon footprint of the attendees.

What’d I miss?
