Ken Caldeira

Ken Caldeira conducts research at the Carnegie Institution for Science's Department of Global Ecology, located at Stanford University. His work there focuses on the global carbon cycle, climate change, and the interactions between atmospheric carbon dioxide and marine ecosystems.

Caldeira is widely recognized for his research on ocean acidification, the process by which excess atmospheric carbon dioxide dissolves into seawater and lowers its pH. His work has been influential in documenting how acidification threatens marine organisms that build calcium carbonate shells and skeletons.

Yes, Caldeira has published research on various climate intervention strategies, including solar radiation management and direct carbon capture approaches. His modeling work suggests that while some geoengineering techniques could temporarily reduce global temperatures, they carry significant ecological and political risks and cannot substitute for reducing greenhouse gas emissions.

The Department of Global Ecology is part of the Carnegie Institution for Science, a private research organization founded by Andrew Carnegie in 1902. The department is physically located on the campus of Stanford University in California, where it conducts interdisciplinary research on Earth's environmental systems.
