Because of the many risks of solar geoengineering, we urgently need an International Non-Use Agreement on Solar Geoengineering, which is supported by 550+ academics and 2000 civil society organizations. More information at www.solargeoeng.org.

Solar Geoengineering Non-Use Agreement

Our initiative stands against such emerging initiatives to explore planetary techno-fixes as a climate policy option.

This is what should be on every front page right now. What's happening in the US right now is an illegal power grab by a private citizen. IT'S A COUP.

It's a digital coup. It's Musk who's leading it. The consequences are terrifying. And it's coming for us next.

Just interviewed by "Undark" magazine on the many risks and dangers of solar geoengineering. The article also highlights the alarming private investments pouring into this speculative, planet-altering tech. Open access: undark.org/2024/12/03/u... #ClimateRisk #Geoengineering

Geoengineering Could Alter Global Climate. Should It?

Scientists and companies increasingly support blocking some sunlight to avoid the worst impacts of global warming.

Vanuatu stands firmly against solar geoengineering, linking it to crime of ecocide: “Vanuatu is advocating for a ban or non-use agreement on solar geoengineering. ...such an agreement is necessary to ... protect the world’s most vulnerable peoples & ecosystems.”

Can I please draw attention to this important initiative which is now joining us here. Solar radiation manipulation (i.e. the direct injection of particles into the stratosphere) implies truly existential risks and it offers - regrettably - no solution for the currently ongoing planetary crisis.
