Geoengineering Technologies explained
The notion of geoengineering includes a wide array of technologies centred around reflecting sunlight back into space or removing carbon dioxide from the atmosphere. All seek to intervene in and alter earth systems on a large scale – a “technofix” to climate change.
The technologies proposed all come with far-reaching and profound social, political, and environmental risks and impacts. The effects would - by nature of the intervention - be transboundary, as well as potentially large-scale, unpredictable and irreversible.

Geoengineering worldwide
This interactive geoengineering map, prepared by ETC Group and the Heinrich Boell Foundation, sheds light on the worldwide state of geoengineering by showing the scope of research and experimentation. There is no complete record of weather and climate control projects so this map is necessarily partial.

Podcast on geoengineering
Can and should the global climate be regulated by technological means, the so called geoengineering? In our first episode of our podcast "Tipping point" our host took off to hear from experts what these approaches mean for the planet’s environment and society.
