Bernie Sanders backs new climate plan to curb US fossil fuel extraction

Senator co-sponsors Keep it in the Ground Act in bid to ban all new fossil fuel leases on public lands, something activists view as a gap in Obama's climate plan

Bernie Sanders launched a new climate campaign on Wednesday, aimed at fighting global warming by banning new coal, oil and gas mining on public land.

The Keep it in the Ground Act co-sponsored by the senator and Democratic presidential candidate aims at plugging one of the big gaps in Barack Obama's climate change plan: his administration's continued sanction of fossil fuel extraction on the government's lands and waters.
