Largest Methane Leak

The world's largest cruise ship is set for its maiden voyage on Saturday, but environmental groups are concerned that the liquefied natural gas-powered vessel - and other giant cruise liners to follow - will leak harmful methane into the atmosphere.

A natural gas well in California that spewed more than 100,000 tons of the harmful greenhouse gas methane into the atmosphere was the largest methane leak in US history, researchers said Thursday.
