Geoengineering

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.

Our three explanatory videos describe how geoengineering technologies are supposed to work on land, in the oceans and in the atmosphere, and the risks associated with these large-scale technological approaches.

Solar Geoengineering: Warnings from Scientists, Indigenous Peoples and Climate Activists

Greta Thunberg, Vandana Shiva, Tom Goldtooth, Naomi Klein, Åsa Larsson Blind, Bill McKibben, Michael Mann, Raymond Pierrehumbert and Jennie Stephens share their perspectives — and their warnings — on the growing issue of solar geoengineering.

SolarGeoengineering is a dangerous bogus solution to the climate crisis that poses serious risks to the environment and society.

Frequently Asked Questions on 1.5°C and Geoengineering

What's the difference between 1.5°C and 2°C? What are "negative emissions"? What's the problem with geoengineering? Why and how is the Heinrich Böll Foundation working on the topic of geoengineering and the 1.5°C limit? Answers to the most frequently asked questions about the 1,5°C target and the topic of geoengineering.

Webinar

Join CIEL, Heinrich Böll, Oil Change International, and DiCaprio Foundation/OneEarth for three short presentations and a Q&A on three seminal reports on geoengineering.The presenters answered questions following presentations about each of these reports.

Geoengineering at UNEA-4: Why the SDGs Require a Governance Debate Based on Precaution, Rights and Fairness

Commentary

Setting aside the false promise of geoengineering and focusing on both accelerating the energy transition and truly protecting and restoring our ecosystems so that they can act as carbon sinks, is the safest and surest way to confront the climate crisis.

Geoengineering is a dangerous distraction

Analysis

Geoengineering technologies are considered by many to be the most practicable solution to overcome the climate crisis. They are mainly a means to secure the predominant role of fossil fuels in the economy.

Fuel to the Fire

The present report investigates the early, ongoing, and often surprising role of the fossil fuel industry in developing, patenting, and promoting key geoengineering technologies.

Radical Realism for Climate Justice

Dossier

Limiting global warming to 1.5°C above pre-industrial is feasible. Our Dossier is a civil society response to the challenge of such a limitation that's also paving the way for climate justice. Because it’s is neither ‘naïve’ nor ‘politically unfeasible’, it is radically realistic.

The Big Bad Fix: The case against geoengineering

Report

The “Big Bad Fix” provides a comprehensive overview of the key actors, technologies and fora relevant in the geoengineering discourse. It opposes geoengineering as a technofix for climate change and as a threat to world peace, democracy and human rights.

Governing the Big Bad Fix? What to do about geoengineering

Geoengineering – large-scale manipulation of the Earth’s natural systems – is increasingly being presented as a strategy to counteract, dilute or delay climate change. Which international legal norms and agreements would contradict the different measures?

By Duncan Currie

The geoengineering fallacy

Geoengineering technologies are not yet deployable globally, but support for them is advancing fast, thanks to backing by powerful advocates eager to start experiments. But no silver bullet for climate change exists, and we must not abandon proven methods for the sake of a promise that one will be found.

Geoengineering Briefing: Stratospheric Controlled Perturbation Experiment (SCoPEx)

Briefing on the details and possible impacts of the Stratospheric Controlled Perturbation Experiment - a planned experiment in a form of geoengineering known as Solar Radiation Management (SRM). SRM aims to block or reflect sunlight before it reaches the earth’s atmosphere.

The risks of large-scale biosequestration in the context of Carbon Dioxide Removal

The Paris Agreement’s target of limiting global temperature rise to 1.5 degrees is largely dependent on Carbon Dioxide Removal (CDR) approaches and climate finance institutions are already supporting such afforestation schemes. The report describes existing trends in the field of large-scale biosequestration and examines the social and ecological impacts of such projects.

Using Data and Technology to Solve Social, Environmental and Political Problems

This essay adopts broader conceptual analysis on technology deployment for social change. It looks at how data-driven technologies are currently deployed to solve problems. And makes a case for why we cannot leave the challenges posed by data-driven technologies to technologists.

What is wrong with Solar Radiation Management?

A briefing explaining why Solar Radiation Management (SRM) experiments are a bad idea. SRM describes a set of geoengineering techniques that aim to counter human-made climate change by artificially increasing the reflection of heat from sunlight (solar radiation) back into space.

Climate change, smoke and mirrors - A civil society briefing on Geoengineering

For the past decade, a small but growing group of governments and scientists, the majority from the most powerful and most climate-polluting countries in the world, has been pushing for political consideration of geoengineering, the deliberate large-scale technological manipulation of the climate.

Riding the GeoStorm - A briefing from civil society on Geoengineering Governance

The prospect of controlling global temperatures raises serious questions of power and justice: Who gets to control the Earth’s thermostat and adjust the climate for their own interests? Who will make the decision to deploy if such drastic measures are considered technically feasible, and whose interests will be left out?

There is no complete record of weather and climate control projects so this map is necessarily partial.

Last-ditch climate option or wishful thinking?

This report summarises the key evidence which must be considered about BECCS. It looks at the overwhelmingly destructive impacts of existing large-scale bioenergy production and use and the implications of massively scaling it up, as would be required for a global BECCS programme.

A change of course - How to build a fair future in a 1.5° world

In Paris in 2015 governments agreed to keep global warming to well below 2 degrees. The mainstream pathways pin theirhopes to risky and costly technologies. In this joint publication, together with Friends of the Earth Germany (BUND) and Misereor, we present alternatives that are possible and necessary for a change of course.
