“We Can’t Be Sidelined Forever”: Why Stratospheric Aerosol Injection Must Move From Taboo to Testing

A decade ago, I helped convene SRM Science 2015 in Cambridge to focus squarely on the science and engineering of solar radiation management. We brought ethics and governance into the room too, but the goal… Read More »“We Can’t Be Sidelined Forever”: Why Stratospheric Aerosol Injection Must Move From Taboo to Testing

Greenhouse Gas Removal: a critical component to cool the Earth system

It is important to note from the outset that reducing emissions is, without question, critical. But it is equally vital to understand that it won’t be enough on its own. The simple truth is that… Read More »Greenhouse Gas Removal: a critical component to cool the Earth system

COP29 must acknowledge geoengineering as necessary to fight extreme climate impacts

Carbon emission reductions are not happening fast enough and, even if they were, Professor Hugh Hunt argues they are now not enough to prevent dangerous climate impacts. Here he gives his reasons why future COP’s… Read More »COP29 must acknowledge geoengineering as necessary to fight extreme climate impacts

The Imperative for Marine Cloud Brightening: A Call for $100 Million to Preserve Arctic Sea Ice

In this sequel to Professor Hunt’s previous article on preserving Arctic sea ice, he addresses the need for a large-scale research initiative to investigate marine cloud brightening (MBC). The Arctic is often referred to as… Read More »The Imperative for Marine Cloud Brightening: A Call for $100 Million to Preserve Arctic Sea Ice
