"In terms of resolving these two problems of peak fossil fuels and climate change... mitigation policies for peak oil, peak coal and peak gas should be done in tandem with mitigation policies for climate change. And I think there's no reason that that shouldn't happen. In fact it makes the most sense to me." NASA research scientist Dr. Pushker Kharecha speaks with David Room about "Implications of 'peak oil' for atmospheric CO2 and climate," a paper Kharecha co-wrote with one of the world's foremost climate scientists, Dr. James Hansen. The paper, which has been submitted for peer-reviewed publication in a scientific journal, is one of few that consider both climate instability and oil depletion.
