Apparently the science is settled — to the bottom:

Red Sea Huge Source of Air Pollution, Greenhouse Gases: Study

Hydrocarbon gases bubbling from the bottom of the Red Sea are polluting the atmosphere at a rate equivalent to the emissions of some large fossil fuel exporting countries, researchers said Tuesday.

The gases [are] seeping from the waters—which are ringed by the resorts and ports of several countries, including Egypt, Israel, Jordan and Saudi Arabia . . .

(“Saud DARE You!?!”)

During a 2017 expedition around the Gulf, researchers at the Max Plank Institute for Chemistry noticed that levels of ethane and propane in the air above the Northern Red Sea were up to 40 times higher than predicted, even accounting for regional manmade emissions.

The team analysed possible sources for the gas emissions, including traffic, agriculture, burning of biomass, and power generation from hydrocarbons.

They came to an unexpected conclusion: the two gases had to be seeping out of the sea bed after escaping natural subterranean oil and gas reservoirs.

I’m sure this is the only place on earth this is happening. I guess volcanoes and farting cows will just have to wait and see.
