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?
Earth is fast approaching the red lines that scientists have urged temperatures cannot cross if we have any hope of avoiding catastrophic climate change. Here are the emergency measures we need.
In the context of accelerating geopolitical, technological and environmental change, we need to radically reassess how we perceive airspace legally.
Climate mitigation efforts are unlikely to be enough to save critical ecosystems like the Great Barrier Reef. We may need to consider more radical environmental engineering.
Universities must train scientists to engage with the ethics of emerging technologies, rather than functioning as cogs in the engine of economic development. Integrating the arts into STEM can help.
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.
It's increasingly likely that at some point, the world's nations will need to broach the fraught discussion of geoengineering. The UN climate accord was a natural forum to do it.
Scientists want to exploit a natural process of carbon storage.
It's a daunting technical challenge. But the key question is whether such engineering is socially acceptable.
The Paris agreement has given us some solid targets to aim for in terms of limiting global warming. But that in turn begs a whole range of new scientific questions.
Yes, we blunt the effects of climate change by getting off fossil fuels. But countries' most ambitious targets imply use of climate engineering schemes – and that discussion should be done in public.
We're going to have to adapt to climate change, but some of the options on the table could do more harm than good if they destroy the ecosystems that protect us.
