Hydraulic fracking is getting a pretty bad reputation for its potential to pollute water, cause cancer, and trigger earthquakes — need we go on? But a new study from Cornell reports that the natural gas extraction technique may be more harmful than even coal when it comes to global warming. The research team has updated their controversial findings with fresh data to support the conclusion that fracking in a major source of released methane. The study looks at how much gas is released into the atmosphere, revealing a significant jump in atmospheric methane. Methane, as compared to CO2, has the potential to trap over 100 times more heat over the course of ten years, making fracking one of the most environmentally destructive ways to source energy.
