Integrating physical, engineering and social sciences to construct a framework for assessing effectiveness and side effects of geoengineering proposals.

The IAGP project was funded from October 2010 to February 2015.

IAGP Research: What have we learned?

Our key findings are presented in a series of Briefing Notes: 

Briefing note 1Briefing note 2Briefing note 3Briefing note 4


August 2015: A Comparison of Temperature and Precipitation Responses to Different Earth Radiation Management Geoengineering Schemes

In this latest study, published in the Journal of Geophysical Research: Atmospheres, IAGP researchers Julia Crook and Lawrence Jackson consider how effective different Earth radiation management schemes are at counteracting global warming. Read more.

February 2015: Not enough time for geoengineering to work?

In his latest article in the Bulletin for Atomic Scientists, IAGP Principal Investigator and IPCC Lead Author, Piers Forster describes the research and conclusions drawn from IAGP’s examination of geoengineering technologies over the past four years. Read more

January 2015: Could we Restore Arctic Sea Ice with Geoengineering?

In a paper just published in Geophysical Research Letters IAGP researchers perform a novel simulation where we see if it is possible to restore Arctic sea-ice using stratospheric aerosol injected by planes flying out of Svalbard. More

January 2015: Forcing, feedback and internal variability in global temperature trends

In this latest study, published in Nature, authors Piers Forster (IAGP Principal Investigator) and Jochem Marotzke, MPI, compared climate observations with simulated 15-year trends over the period 1900-2012. The research concluded that the claim that climate models systematically overestimate the response to radiative forcing from increasing greenhouse gas concentrations seems unfounded. More

Geoengineering Research: Where Next?

On 26th November 2014, three UK geoengineering research projects, IAGP, SPICE and CGG, held a joint event, Geoengineering Research: Where Next?, at The Royal Society in London to disseminate our research findings.

Read the press release for the dissemination event.
