Ken Caldeira of Stanford University’s Carnegie Department of Global Ecology, says global warming will likely continue even if emissions of green house gases and carbon fall. For the earth to cool would take zero emissions, he starkly points out.
One route to mitigate global warming is geoengineering or using human-developed technologies to alter climate on a global scale. Caldeira is at the forefront of this controversial process, having just shared a $4.5 million funding from Bill Gates to to find and support promising geoengineering technologies.
