With climate change threatening ski towns around the world, recent design graduate Tanay Wadodkar has created a small-scale geoengineering intervention in the form of snow-generating stickers. More about Snow-generating stickers help fight climate change effects in ski resorts
Following a proposal by MIT to create climate-change-fighting bubbles, here is a roundup of 10 inventions aimed at limiting the impact of architecture and design on our environment. More about Ten scientific inventions to reduce design and architecture's impact on the planet
Architect Carlo Ratti is among a group of MIT researchers exploring the feasibility of fighting climate change with a conglomeration of "space bubbles" that would float above the Earth to reflect the sun's rays. More about MIT researchers propose using Space Bubble shield to reflect the sun
One of the award-winning projects from this year's Design Academy Eindhoven graduation show explores how humans might use geoengineering to develop a more intimate relationship with the climate. More about Filips Staņislavskis' Human-Cloud Project turns human breath into clouds
Turning the USA into a net-zero carbon economy could involve covering a landmass equivalent to seven states in geoengineering infrastructure, according to environmental social scientist Holly Jean Buck. More about Persuading communities to accept the vast solar and wind farms needed to reach net-zero "will be a challenge"
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 about Iceberg-making submarine aims to tackle global warming by re-freezing the Arctic
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 about Salk Institute develops a plant that offers a solution to climate change
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 about Scientists turn carbon dioxide back into coal
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 about First geoengineering experiment to dim the sun on track for 2019
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 about Artificial mountain made of soil could soak up pollution in Turin
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?
