Campaigners frustrated at how women and indigenous people have struggled to have voices heard

Youth climate activists have called for a global strike on Friday to protest that human rights and social justice have been sidelined at the UN climate talks in Madrid, where governments look set to wrap up two weeks of negotiations without a breakthrough on the pressing issue of greenhouse gas reduction.

Campaigners have been frustrated not only at the slow progress of the talks but also that groups representing women, indigenous people and poor people have struggled to have their voices heard within the conference halls where the official negotiations are taking place, even while 500,000 people took part in a mass protest in the streets outside last Friday.
