It is my sad duty to report that Dr. Charles David Keeling
died of a heart attack while hiking with is son on his ranch
in Montana this Monday, the 20th of June. Those of us
who frequent alt.global-warming are well aware of both
Dr. Keeling's works: directly measuring atmospheric CO2
concentrations, and the curve of CO2 concentrations
named after him. Please see:
