Climate change: World will need 'carbon sucking' technology by 2030s, scientists warn https://www.theguardian.com/environment/2017/oct/11/world-will-need-carbon-sucking-technology-by-2030s-scientists-warn 11 Oct 2017
We’re going to have to deploy negative emission technology at scale,” said Bill Hare of Climate Analytics, a science and policy institute. “I don’t think we can have confidence that anything else can do this,” But efforts to store captured carbon underground are “showing no progress … and even backwards steps in some cases”, said Corinne Le Quéré, director of the Tyndall Centre for Climate Change Research at the University of East Anglia.
Similarly, planting more forests – a technology known as Beccs, or bioenergy with carbon capture and storage – raises questions about food security and land rights, scientists said.
New methods to capture and store emissions, such as planting more forests and pumping carbon underground,
are currently costly and need testing
