No matter how you drill it, using natural gas as an energy source is a smart move in the battle against global climate change and a good transition step on the road toward low-carbon energy from wind, solar and nuclear power.
That is the conclusion of a new study by Cornell Professor Lawrence M. Cathles, published in the most recent edition of the peer-reviewed journal Geochemistry, Geophysics and Geosystems. Cathles, a faculty member in Cornell’s Department of Earth and Atmospheric Sciences, reviewed the most recent government and industry data on natural gas “leakage rates” during extraction, as well as recently developed climate models.
He concluded that no matter the timeframe considered, substituting natural gas energy for all coal and some oil production provides about 40 percent of the global warming benefit that a complete switch to low-carbon sources would deliver.
