Solar geoengineering for profit

A pile of one hundred dollar bills scattered and overlaid with a warm, golden light effect.

The Israeli-U.S. startup Stardust Solutions announced last week that it raised $60 million in venture capital in its latest funding round – the largest venture investment to date for a for-profit company developing solar geoengineering technology, particularly injection of reflective particles into the stratosphere. Advocates of solar geoengineering are dismayed. But why are they surprised? […]

Launching the Tyndall Centre Amidst Floods, a Hung Vote and a COP Failure

A panel of five people sit on stage under banners for the Tyndall Centre and University of East Anglia, as one man speaks at a podium about climate challenges like floods at COP.

Is the quest for net-zero a form of scientism?

Discussing a tendency in contemporary politics to reduce issues to questions of scientific measures of climate change, Mike Hulme argues for more diverse understandings of climate and change and its impacts on society. I discussed these ideas in my lecture at the London School of Economics, ‘Epistemic Pluralism and Climate Change’ on 10 March 2025, […]
