On my last couple of days in Cancun, while vestiges of the sense of despondency and low achievement of the initial days remain, Indian environment minister Jairam Ramesh's impromptu statement on "binding commitments" and "appropriate legal form" has jerked many pundits -- especially those from the subcontinent -- up.

How does the UNFCCC select its various locations for its annual climate change meets? What I am hinting at is, why Cancun? Why, for that matter, Copenhagen, Poznan or Bali? I have been told that cities vie for the honour, just like a sporting event such as the Olympics or the Asiad, and pay for it.
