Mary Robinson, former UN high commissioner for human rights, is set to argue in a speech that climate change is an issue of global injustice.

An excerpt from the BBC story:

The ex-UN high commissioner for human rights will urge policymakers to adopt "a radically different approach".

She will also urge rich nations to meet their climate change obligations.

"We can no longer think of climate change as an issue where we the rich give charity to the poor to help them cope," she is expected to say.

"Climate change has already begun to affect the fulfilment of human rights and our shared human rights framework entitles and empowers developing countries and impoverished communities to claim protection of these rights."

Ms Robinson will argue for the revival of multilateral efforts that led to the global eradication of smallpox and the phasing out of CFC gases.
