Katowice COP24: Protesters raise the alarm on climate

Talks billed as the most important U.N. conference since the Paris 2015 deal on climate change are nearing the end of a first week in the Polish city of Katowice, the capital of the Silesian mining district.
The aim is to make an end-of-year deadline for agreeing on a rule book on how to enforce global action to limit further warming of the planet.
At noon, demonstrators are expected to take to the streets of Katowice as well as cities around the world to demand an agreement that will prevent temperatures rising by more than 1.5 C.
The marchers' symbol is an alarm clock, as organizers seek to wake governments up to the urgency of action.
