Climate change activists vow to step up protests around world

Campaigners say they will force governments to act after lack of progress at UN summit

Civil society groups have pledged growing international protests to drive rapid action on global warming after the UN climate summit in Poland.

The summit agreed rules for implementing the 2015 Paris agreement, which aims to keep global warming as close to 1.5C (2.7F) as possible, but it made little progress in increasing governments' commitments to cut emissions. The world remains on track for 3C of warming, which scientists says will bring catastrophic extreme weather.
