PhysOrg: Climate: Removing CO2 from the air no longer optional

„The burning question going into the Glasgow climate summit is whether major economies can, by 2050, reduce emissions enough to deliver a carbon neutral world in which humanity no longer adds planet-warming gases to the atmosphere. Less talked about—but rising quickly on the climate agenda—are tools and techniques to pull CO2 straight out of the air. Even scientists sceptical about its feasibility agree that without carbon dioxide removal (CDR)—aka „negative emission“—it will be extremely difficult to meet the Paris Agreement goal of capping global warming below two degrees Celsius. ‚We need drastic, radical emissions reductions, and on top of that we need some CDR,‘ said Glen Peters, research director at the Centre for International Climate Research.“
