Adding industrial chemicals and natural alkaline minerals could slow climate change, but like other geoengineering proposals, it comes with many complex technical and legal challenges.
For the second year in a row global greenhouse emissions from fossil fuels have risen, putting 2018 on course to set a new record, according to an annual audit from the Global Carbon Project.
Technology exists to capture carbon dioxide from the atmosphere but it has a big cost.
A disaster fantasy raises questions about tinkering with Earth's climate. With real-life scientists exploring geoengineering, what conversations should we be having now around these technologies?
The prospect of attempting to engineer the world's climate has become a lot more real since the Paris Agreement.
Global warming and carbon emissions, left unchecked, could cause rising sea levels and displace almost 200 million people. But we can still prevent the worst case scenario if we act now.
Carbon capture and storage gets a bad rap from its associations with 'clean coal'. But the technology could prove vital in cutting emissions from other industries like steel, cement and chemicals.
Phasing out greenhouse gas emissions entirely by mid-century is possible, and promising trends are emerging. But the next five to ten years will be the real test of whether we can make that happen.
Despite advances in technology, carbon capture and storage could be unsettled by renewable upstarts.
Sometime soon we'll need to take more carbon out of the atmosphere than we emit – but how?
A new method for creating a form of graphene with carbon dioxide sucked from the air has been announced with misleading claims.
Like it or not we are going to have to figure out how to suck lots of carbon out of the atmosphere.
