Oil and gas production is contributing even more to global warming than was thought, study finds

(CNN)Among greenhouse gases, carbon dioxide is the most significant contributor to global warming and therefore, public enemy No. 1 when it comes to stopping the climate crisis.

But methane — the main component in natural gas and an even more effective heat-trapping gas — is a close second. Scientists say that atmospheric methane is now responsible for about 25 percent of the human-caused warming we see today.
