The world will need "carbon sucking" technology by 2030s, scientists warn.
As efforts to cut planet-warming emissions fall short, large-scale projects to suck carbon dioxide out of the atmosphere will be needed by the 2030s to hold the line against climate change, scientists have said.
“If you’re really concerned about coral reefs, biodiversity [and] food production in very poor regions, we’re going to have to deploy negative emission technology at scale,” said Bill Hare of Climate Analytics, a science and policy institute.
