“For this to be effective, we need to be there for 20, 30, 40 years, have a long-term data set and then we can start to make useful predictions. We know there is so much complexity involved, we want to tread more cautiously. Maybe in 10 years time, it’ll all start to freeze over, we just don’t know.”
Wayne Hocking professor of physics, University of Western Ontario, Head of the Atmospheric Dynamics Group
