Technology briefings
Artificial Upwelling
Carbon Dioxide Removal
Pumping nutrient-rich deep ocean waters to the surface to stimulate phytoplankton growth.
Biochar
Carbon Dioxide Removal
Burning biomass in a low oxygen environment to make a charcoal-like substance and adding it to soils.
Bioenergy with Carbon Capture and Storage
Carbon Dioxide Removal
Capturing the carbon dioxide emitted from bioenergy generation and injecting it underground.
Carbon Capture and Storage
Carbon Dioxide Removal
Capturing carbon dioxide as it is released from smokestacks and injecting it into geological formations.
Carbon Capture Use and Storage
Carbon Dioxide Removal
Capturing carbon dioxide as it is released from industrial processes and using it for manufacturing.
Cirrus Cloud Thinning
Solar Radiation Management
Releasing substances at high altitudes that thin cirrus clouds.
Direct Air Capture
Carbon Dioxide Removal
Sucking carbon dioxide out of the air and then injecting it underground or using it for other purposes.
Enhanced Photosynthesis
Carbon Dioxide Removal
Manipulating the genetic make-up of plants or algae so that they exhibit “more efficient” photosynthetic traits.
Enhanced Weathering
Carbon Dioxide Removal
Crushing millions of tonnes of rocks and spreading them on land and in the oceans.
Marine Cloud Brightening
Solar Radiation Management
Spraying salt water aerosols into clouds so that they reflect more sunlight.
Microbubbles and Sea Foam
Solar Radiation Management
Injecting tiny air bubbles or spraying sea foam to reflect light away from the oceans.
Ocean Alkalinity Enhancement
Carbon Dioxide Removal
Making seawater more alkaline so that it can absorb more carbon dioxide from the atmosphere.
Ocean Fertilisation
Carbon Dioxide Removal
Drawing carbon dioxide out of the atmosphere by dumping iron into the ocean to stimulate plankton growth.
Seaweed Farming and Biomass Sinking
Carbon Dioxide Removal
Growing seaweed to capture carbon and sinking it in the deep ocean or utilising it for products.
Stratospheric Aerosol Injection
Solar Radiation Management
Spraying sulfur dioxide and other aerosols into the stratosphere to block the sun.
Surface Albedo Modification and Arctic Ice Management
Solar Radiation Management
Modifying the surface of the Earth in order to reflect more sunlight back into space.
Weather Modification
Weather Modification
Changing local weather patterns, usually in order to increase or reduce precipitation.

Why Geoengineering is “Untested and Untestable”
Feb 6, 2015
by Naomi Klein (This Changes Everything) Nature has a new opinion piece up that signals a bold new push for field experiments into techo hacking the climate system, usually known as “geoengineering.” Right now there are all kinds of geoengineering experiments going on...
Strange Bedfellows? Climate Change Denial and Support for Geoengineering
Oct 30, 2013
by David Appell (Yale Climate Connections) These days, an article headlined “Geo-Engineering Seen as a Practical, Cost-Effective Global Warming Strategy” would hardly be surprising. But what is surprising is that the headline came from a group denying global warming...
Climate Crisis: Radical Action or a New Battlefront in the War on Nature?
Jun 7, 2013
Arctic Methane Emergency Group (AMEG) warns of catastrophic release of methane from permafrost, peat and the thawing Arctic leading to unstoppable runaway warming. Scary, but does it warrant deployment of highly risky geoengineering technologies that are likely to only make matters worse?

Interactive map from ETC Group and Heinrich Boell Foundation shows growth of climate control efforts This interactive geoengineering map, prepared by ETC Group and the Heinrich Boell Foundation, is an attempt to shed light on the worldwide state of geoengineering by...
ETC Group and Heinrich Böll Foundation release interactive world map of geoengineering experiments
Nov 1, 2017
In an attempt to shed light on the worldwide state of geoengineering, ETC Group and Heinrich Böll Foundation have launched an interactive world map of geoengineering experiments, available at: https://map.geoengineeringmonitor.org/ The map is necessarily partial, as...
