THE world鈥檚 richest man has been funding geoengineering research, it emerged last week. According to , Bill Gates has committed $4.5 million of his own money to funding a number of climate scientists interested in geoengineering.
It is not clear whether all of that has gone to geoengineering studies. Atmospheric scientist Ken Caldeira of the Carnegie Institution for Science in Stanford, California, says he received $1.1 million over three years for 鈥渂lue skies鈥� research. He estimates about one-third of that was spent on investigating geoengineering.
Caldeira says he sees no moral dilemmas in Gates funding geoengineering. 鈥淭here is no attempt to profit from this,鈥� he says. He contrasts Gates鈥檚 involvement with commercial geoengineering ventures.
