Solar geoengineering could limit global warming, but Canada should study risks and benefits first

Solar geoengineering could theoretically cool the Earth to slow global warming, and it has been controversial. Still, countries should research its risks and benefits.
Trapping carbon dioxide in minerals happens naturally over thousands of years. Can humans speed it up – safely? Simon Clancy

Can we tweak marine chemistry to help stave off climate change?

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.

STEAM not STEM: Why scientists need arts training

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.
The Paris Agreement could provide a forum for international cooperation on risky, planet-scale engineering to cool the Earth. Tatiana Grozetskaya/

US exit from Paris climate accord makes discussing how and whether to engineer the planet even harder

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.
