China claims breakthrough in mining 'flammable ice'

China has for the first time extracted gas from an ice-like substance under the South China Sea considered key to future global energy supply.

Chinese authorities have described the success as a major breakthrough.

Methane hydrates, also called "flammable ice", hold vast reserves of natural gas.

Many countries including the US and Japan are working on how to tap those reserves, but mining and extracting are extremely difficult.

A potential threat is that methane can escape, which would have serious consequences for global warming. It is a gas that has a much higher potential to impact climate change than carbon dioxide.
