ALBANY, N.Y.: Two groups of scientists at Cornell University are dueling over whether natural gas from shale is better or worse than coal when it comes to global climate change.
It’s a significant question because proponents of shale gas development using the controversial practice of high-volume hydraulic fracturing argue that natural gas is a cleaner-burning “bridge fuel” from the age of coal to an era of wind, solar and other sustainable energy sources.
Last spring, Cornell scientist Robert Howarth said in the journal Climatic Change that methane releases give shale gas development a worse greenhouse gas footprint than that of coal.
Cornell colleague Anthony Cathles countered the study in the same journal this month, challenging Howarth’s calculations and conclusions.
On Thursday, Howarth presents new evidence against gas as a bridge fuel.
