Carbon dioxide emissions are rising so fast that some scientists are seriously considering putting Earth on life support as a last resort. But is this cure worse than the disease? 

Climate engineering reconsidered

Stratospheric injection of sulphate aerosols has been advocated as an emergency geoengineering measure to tackle dangerous climate change, or as a stop-gap until atmospheric carbon dioxide levels are

A resilience view on reframing geoengineering research and implementation

As it becomes harder to see how the world will keep GHGs in the atmosphere below levels at which global warming of at least 2°C is likely [1], calls for geoengineering approaches to climate managem...

Solar geoengineering reduces atmospheric carbon burden

Solar geoengineering is no substitute for cutting emissions, but could nevertheless help reduce the atmospheric carbon burden. In the extreme, if solar geoengineering were used to hold radiative

Hazy, cool and well fed?

Geoengineering that mimics volcanic activity to reflect incoming sunlight will not necessarily reduce crop yields.

Making War on the Planet

The dangers posed by climate change have inspired a desperate search for technological fixes in the form of geoengineering—massive human interventions to manipulate the entire climate or planet. But

Bioenergy and carbon capture with storage (BECCS): the prospects and challenges of an emerging climate policy response

There is increasing impetus for large-scale deployment of carbon dioxide removal geoengineering approaches to help keep temperatures to below 2 °C, as provided for under the Paris Agreement. The

Public Engagement with Biotechnologies Offers Lessons for the Governance of Geoengineering Research and Beyond

This Perspective looks back on recent experience of public engagement with biotechnologies and asks what can be learned for the governance of another controversial emerging area—geoengineering.

Fixing the Climate? How Geoengineering Threatens to Undermine the SDGs and Climate Justice

Both Carbon Dioxide Removal and Solar Radiation Management schemes are bound to exacerbate concomitant socio-ecological and socio-economic global crises, deepen societal dependence on technocratic elites and large-scale technological systems and create new spaces for profit and power for new and old economic elites.

Efficacy of geoengineering to limit 21st century sea-level rise

The least risky and most desirable way of limiting sea-level rise is bioenergy with carbon sequestration, however aerosol injection or a space mirror system reducing insolation at an accelerating rate of 1 W m-2 per decade from now to 2100 could limit or reduce sea levels.



Global environmental engineering

All the signs are that global ozone depletion is increasing and ideas to mitigate the problem should be considered.

Ocean acidification due to increasing atmospheric carbon dioxide

The oceans cover over two-thirds of the Earth’s surface. They play a vital role in global biogeochemical cycles, contribute enormously to the planet’s biodiversity and provide a livelihood for

Earth systems engineering and management

Imagine that we could let the world's economy continue to grow, bring the disadvantaged classes up from poverty and at the same time not threaten the atmosphere or global ecosystems with

A Combined Mitigation/Geoengineering Approach to Climate Stabilization

This work considers the deliberate injection of sulfate aerosol precursors into the stratosphere, which could substantially offset future warming and provide additional time to reduce human dependence on fossil fuels and stabilize CO2 concentrations cost-effectively at an acceptable level.

Transient climate–carbon simulations of planetary geoengineering

It is found that the climate system responds quickly to artificially reduced insolation; hence, there may be little cost to delaying the deployment of geoengineering strategies until such a time as “dangerous” climate change is imminent.

Geoengineering: Encouraging Research and Overseeing Implementation

It is proposed that research on geoengineering be considered separately from actual implementation, and a path in that direction is suggested.

Response of a Deciduous Forest to the Mount Pinatubo Eruption: Enhanced Photosynthesis

It is found that the aerosol-induced increase in diffuse radiation by the volcano enhanced the terrestrial carbon sink and contributed to the temporary decline in the growth rate of atmospheric carbon dioxide after the eruption.

Geoengineering Earth's radiation balance to mitigate CO2‐induced climate change

To counteract anthropogenic climate change, several schemes have been proposed to diminish solar radiation incident on Earth's surface. These geoengineering schemes could reverse global annual mean

Effects of Mount Pinatubo volcanic eruption on the hydrological cycle as an analog of geoengineering

The problem of global warming arises from the buildup of greenhouse gases such as carbon dioxide from burning of fossil fuels and other human activities that change the composition of the atmosphere

Albedo Enhancement by Stratospheric Sulfur Injections: A Contribution to Resolve a Policy Dilemma?

Fossil fuel burning releases about 25 Pg of CO2 per year into the atmosphere, which leads to global warming (Prentice et al., 2001). However, it also emits 55 Tg S as SO2 per year (Stern, 2005),
