The Napkin Diagram: Understanding Climate Overshoot and Why SRM May Be Needed

When introducing climate engineering, I often begin with something deceptively simple: the napkin diagram. The story is regarding an esteemed colleague John Sheppard, who sketched the original while talking through climate pathways over a meal.… Read More »The Napkin Diagram: Understanding Climate Overshoot and Why SRM May Be Needed

“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

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

Geoengineering is necessary to refreeze the Arctic & stabilize the Northern Hemisphere’s weather system

Preserving the Arctic sea-ice is now an imperative that must be taken seriously by both the political and scientific research community. Professor Hugh Hunt presents a pathway forward for consideration. As the impacts of climate… Read More »Geoengineering is necessary to refreeze the Arctic & stabilize the Northern Hemisphere’s weather system
