Some geoengineering techniques are better understood than others. The US is investing in capturing carbon dioxide from the air, but ideas to block the Sun’s rays are raising big concerns.

Can we engineer oceans to store more carbon dioxide in the fight against climate change? A new bill before parliament seeks to regulate such activity, but holds back on research incentives.
An elaborate scheme to shade Earth with millions of tonnes of Moon dust floating in space is unlikely to get off the ground.
Injecting reflective particles into the atmosphere won’t immediately cool the entire planet. A new study shows how parts of the US, China and Europe might still see temperatures rising a decade later.
Here are two possible forms of regional geoengineering.
A climate scientist looks at what works and some popular ideas that aren’t as cheap or effective as people hope.
New modelling shows how tectonic plate movements, carbon-rich deep-sea sediment, and mountain weathering have regulated Earth’s climate.
Solar geoengineering could temporarily address the worst impacts of global warming.
The risks of using aerosols to reflect sunlight and cool the planet include creating extreme weather and worsening catastrophes.
An engineered climate recovery needs to be taken seriously — in addition to cutting emissions.
Solar geoengineering could theoretically cool the Earth to slow global warming, and it has been controversial. Still, countries should research its risks and benefits.
Is it time to take drastic steps to modify Earth’s climate to avoid catastrophic warming? A panel of experts says the idea deserves study.
The plan has plenty on reducing emissions, but less on removing already-emitted carbon from the atmosphere.
Countries are not on track to meet Paris Agreement goals. A climate researcher argues that a range of technologies that take CO2 out of the air are needed.
The world economy collapsed when homeowners couldn’t repay subprime mortgages. We’re now making a similar bet on ‘repaying’ carbon emissions.
Migration offers a fix for the islands ‘drowning’ as a consequence of the climate crisis – but are there better alternatives?
George Monbiot talks with an ecologist about natural solutions to the climate crisis.
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.
Nations may soon be desperate enough about global warming to consider deliberately engineering the world’s climate.
The realities of climate change look bleak, but is relying on a climate engineering project like solar radiation management the answer?
