The Paris Agreement on climate change, signed on Dec. 12, 2015, by almost 200 states, was hailed as the turning point to keep global warming in check. Progress, however, has been insufficient. (UNclimate change/flickr)

The Paris Agreement at 5: Time’s running out. How to get the world back on track to meet its climate goals

The Paris Agreement set countries on a path to limit global warming. Five years on, some progress has been made, but not enough. Decarbonizing the economy will take leadership and imagination.

An effective climate change solution may lie in rocks beneath our feet

To avoid global warming on a catastrophic scale, nations need to reduce emissions and find ways to pull carbon from the air. One promising solution: spreading rock dust on farm fields.
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.

Why we can’t reverse climate change with ‘negative emissions’ technologies

The UN's panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5 degrees Celsius. But these techniques are largely unproven.
