World will need 'carbon sucking' technology by 2030s, scientists warn
by Reuters from Environment | The Guardian on (#34PJB)
New methods to capture and store emissions, such as planting more forests and pumping carbon underground, are currently costly and need testing
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.
Many new technologies that aim to capture and store carbon emissions, thereby delivering "negative emissions", are costly, controversial and in the early phase of testing.
