As the week wears on here in Copenhagen, attention will keep focusing on who is promising to do what and when, and whether the aggregate results can possibly keep the earth's 21st-century warming from exceeding 2 degrees Celsius, the stated goal of the COP15 conference.
Yesterday, standing in a seven-hour line to get into the Bella Center, I found myself by happy coincidence standing next to Tom Fiddaman, who created the global pledge thermometer or barometer that I recommended in an earlier post. Fiddaman, who obtained a doctorate in systems dynamics at MIT's Sloan School and now lives in Montana where he telecommutes for Ventana Systems, turned me on to a carbon pledge inventory maintained by UNEP, the United Nations Environment Programme.
