California methane leak 'largest in US history'
Geege Schuman stashed this in Geology
The blowout pushed enough of the gas into the air every day to fill a balloon the size of a football stadium.
At its peak, the flow doubled the rate of methane emissions from the entire Los Angeles basin.
The leak was permanently sealed on 18 February. By then almost 100,000 tonnes of methane had poured into the atmosphere.
Wow. The article says it had a larger climate impact than the BP Oil Spill.
