The world’s worst ever oil spill is also the biggest methane leak in human history, US government scientists have said.
The US Geological Survey’s “flow team” has estimated between 4.5 billion to 9 billion cubic feet of natural gas have escaped from BP’s Deepwater Horizon rig since it exploded in April, Associated Press said on June 19.
John Kessler, an oceanographer at the Texas A&M University, told AP the leak was “the most vigorous methane eruption in modern human history”. Scientists think methane makes up 40% to 70% of what is spilling from the damaged BP rig.
