Key Biosphere Scientist in Revolving Door

Will he stay or will he go? ScienceNOW reported in a story yesterday that Columbia University geochemist Wallace Broecker had quit as research coordinator for Biosphere 2, the ecology lab in the Arizona desert. Now it appears that Broecker may stay.

Last week, Peter Eisenberger, vice provost of Columbia's Earth Institute, which runs the facility, said that Broecker had resigned of his own volition. Broecker and Biosphere 2 Executive Director William Harris have refused to comment on the matter. This morning, however, Earth Institute spokesperson Faye Yates told ScienceNOW that Broecker "has not officially resigned" and that a reorganization is "being negotiated right now." Personnel matters in the biosphere, it seems, are as uncertain as its wildly fluctuating carbon dioxide levels.
