Bloomberg Op-ed: Methane Emissions Could Cancel Out Progress on Carbon Dioxide

The biggest cause of global warming is all the carbon dioxide we’ve expelled into the atmosphere since the beginning of industrial times. The greenhouse gas traps heat in the atmosphere, raising temperatures on Earth. Even so, about one-quarter of the warming we’ve had so far is due to a less notorious greenhouse gas: methane, the major component of natural gas. Methane wasn’t much of a worry 20 years ago, but that’s changed since 2007, as methane emissions have accelerated, spiking in 2014 and again in 2018.
