Cop26: what are the chances of keeping the 1.5C target alive?

At the UN climate summit in Glasgow, global environment editor Jonathan Watts examines the emissions-cutting pledges from world leaders as time runs out to prevent catastrophic global heating

Boris Johnson began the Cop26 climate summit in Glasgow by telling fellow world leaders the world was at one minute to midnight" on the Doomsday Clock and must act now to avert a climate disaster.

The Guardian's global environment editor, Jonathan Watts, has been in Glasgow all week to follow the events as they unfolded. He tells Nosheen Iqbal there have been significant announcements on deforestation, methane reduction and climate finance, but the final week of the conference must have more commitments on reducing global emissions if the target of limiting global heating to 1.5C is to be kept alive.
