Research Letters, ocean iron fertilization can only prove successful as a climate
geoengineering approach

While teaching about this I got excited about doing more
research and ultimately, at John Hopkins, Simon Nicholson from American University and I decided that there should be a think tank that would try to ensure that
if we do decide to look at climate
geoengineering as a society, that we include all of the stakeholders... That was one of the fears we had, so the purpose of these kind of forums are to ensure that other stakeholders like NGOs and the general public — who would be affected by these technologies — are a part of the conversation.

research on any
