World Will Need "Carbon Sucking" Technology by 2030s, Scientists Warn

Scientists say that large-scale projects to suck carbon dioxide out of the atmosphere will be needed by the 2030s to hold the line against climate change: 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. But "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.

World leaders agreed in 2015 an aim of holding global warming to 1.5C above pre-industrial times. Scientists believe this is key to protecting small island nations from sea level rises, shoring up food production and preventing extreme weather. Carbon-sucking technologies may even be needed to hold the planet to a less ambitious two degrees of warming, said scientists at Chatham House, a British thinktank. The world has already seen an average of about one degree of warming, they said.
