Filtering out a portion of sunlight from entering the Earth's atmosphere is being explored as a way of reducing some of the impacts of climate change.
It's a theoretical proposal known as Solar Radiation Management or SRM, and is referred to as solar geo-engineering, climate engineering and climate intervention.
The SRM Governance Initiative is looking at its potential as a weapon in the climate change mitigation arsenal particularly for countries at the forefront of climate change.
The initiative is a partnership between the Royal Society, The World Academy of Sciences, and the Environmental Defense Fund.
The initiative's project director Andy Parker says it's a conversation climate communities in the Pacific should start having.
