Methane emissions head towards catastrophic levels

Surging methane emissions threaten to undermine efforts to slow climate change, a team of international experts has warned.

Concentrations of methane, a powerful greenhouse gas, are now growing faster in the atmosphere than at any time in the past two decades, it is claimed.

The scientists call for urgent action to avoid methane jeopardising efforts to cap global warming at 2C above pre-industrial levels.
