UN hosts drive to suck back carbon and reverse climate change

New York forum aims to 'restore' the climate by reducing atmospheric levels of carbon to those of a century ago

A new effort to rally governments and corporations behind technologies that suck greenhouse gases from the atmosphere to help stave off disastrous global heating will be launched at the United Nations on Tuesday.

The first annual Global Climate Restoration Forum, held in New York, aims to spur international support for emerging and sometimes controversial methods to claw back planet-warming gases after they have been emitted from power plants, cars, trucks and aircraft.
