Reduce methane or face climate catastrophe, scientists warn

Exclusive: IPCC says gas, produced by farming, shale gas and oil extraction, playing ever-greater role in overheating planet

Cutting carbon dioxide is not enough to solve the climate crisis - the world must act swiftly on another powerful greenhouse gas, methane, to halt the rise in global temperatures, experts have warned.

Leading climate scientists will give their starkest warning yet - that we are rushing to the brink of climate catastrophe - in a landmark report on Monday. The Intergovernmental Panel on Climate Change will publish its sixth assessment report, a comprehensive review of the world's knowledge of the climate crisis and how human actions are altering the planet. It will show in detail how close the world is to irreversible change.
