A team of designers led by Faris Rajak Kotahatuhaha proposes re-freezing sea water in the Arctic to create miniature modular icebergs using a submarine-like vessel, in a bid to combat climate change. More
California's Salk Institute for Biological Studies is developing a plant that can store excess carbon dioxide in its roots, in a bid to curb the effects of climate change. More
Carbon dioxide could be removed from the atmosphere and stored as a solid in a bid to manage climate change, using a new technique pioneered at Australia's RMIT University. More
Harvard scientists will attempt to replicate the climate-cooling effect of volcanic eruptions with a world-first solar geoengineering experiment set for early 2019. More
Sponge Mountain is a proposal by architect Angelo Renna for a 90-metre-high mound of soil, which would absorb carbon dioxide from the air in Turin. More
If humans can't reduce greenhouse-gas emissions, can we design our way out of climate-change catastrophe? Last week's UN report shone a light on geoengineering, a discipline that proposes large-scale interventions to counteract global warming. So what ideas are geoengineers proposing? More
A groundbreaking plant where carbon dioxide is sucked from the air before being resold has opened in Switzerland. More
