Science Newsline: Geoengineering Risks Losers as Well as Winners for Climate And Wildfire Risks

"However, the new research suggests that this method of geoengineering could also introduce its own new impacts by shifting global rainfall patterns. The research by scientists at the University of Exeter and the Met Office Hadley Centre, carried out as part of the EU-funded project HELIX, looked at the implications of this for global patterns of wildfire using computer models of the global climate."

Phys.org: Geoengineering risks losers as well as winners for climate and wildfire risks

"Artificially altering the climate system to limit global warming to 1.5C could increase the risks of wildfires in some areas, new research suggests. While the international community is already aiming to limit global warming to below 2C by reducing greenhouse gas emissions, the more ambitious aim of a 1.5C limit is known to be challenging to reach in this way.

Burton, C.; et al. (2018): Will fire danger be reduced by using Solar Radiation Management to limit global warming to 1.5°C compared to 2.0°C?

Burton, C.; Betts, R. A.; Jones, C. D.; Williams, K. (2018): Will fire danger be reduced by using Solar Radiation Management to limit global warming to 1.5°C compared to 2.0°C? In Geophys. Res. Lett. DOI: 10.1002/2018GL077848.

"Here we assess one theoretical solution using Solar Radiation Management to limit global mean warming to 1.5°C above pre‐industrial temperatures, and use the McArthur fire danger index to evaluate the change in fire danger. The results show that globally fire danger is reduced in most areas when temperatures are limited to 1.5°C compared to 2.0°C. The number of days where fire danger is ‘high’ or above is reduced by up to 30 days per year on average, although there are regional variations. In certain regions, fire danger is increased, experiencing 31 more days above ‘high’ fire danger. "

Burns, Wil; Nicholson, Simon (2017): Bioenergy and carbon capture with storage (BECCS). The prospects and challenges of an emerging climate policy response

Burns, Wil; Nicholson, Simon (2017): Bioenergy and carbon capture with storage (BECCS). The prospects and challenges of an emerging climate policy response. In J Environ Stud Sci 15 (2), p. 1360. DOI: 10.1007/s13412-017-0445-6.

"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 primary option that has been discussed to date is Bioenergy with carbon capture and storage (BECCS). While BECCS could sequester very large amounts of carbon dioxide, it also poses substantial socio-economic risks to society, as well as threats to biodiversity. This essay suggests that a human rights-based approach can help to protect the interests of those who might be adversely impacted by BECCS deployment."

Bulletin of the Atomic Scientists: The trouble with geoengineers “hacking the planet”

"Harvard crosses the Rubicon. But what has really catapulted the idea into the public eye is Harvard’s reckless plan for a privately-funded field trial testing some of the key elements needed for albedo modification"

ETC Group: Why SRM experiments are a bad idea

"Solar Radiation Management (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. Some advocates have started using the term “solar geoengineering” – but these techniques are not related to solar power production."

Global Priorities Project (2017): Existential Risk. Diplomacy and Governance

Global Priorities Project (2017): Existential Risk. Diplomacy and Governance.

"Geoengineering technologies like Solar Radiation Management have the potential to mitigate risks from climate change, while at the same time posing risks of their own. The current lack of international norms on acceptable research practices may well be holding back safe exploration of climate engineering options."

Keith, David W.; Irvine, Peter J. (2016): Solar geoengineering could substantially reduce climate risks—a research hypothesis for the next decade

Keith, David W.; Irvine, Peter J. (2016): Solar geoengineering could substantially reduce climate risks—a research hypothesis for the next decade. In Earth’s Future, n/a‐n/a. DOI 10.1002/2016EF000465.

"We offer a hypothesis that if SG were deployed to offset half of the increase in global-mean temperature from the date of deployment using a technology and deployment method chosen to approximate a reduction in the solar constant then, over the 21st Century, it would (a) substantially reduce the global aggregate risks of climate change, (b) without making any country worse off, and (c) with the aggregate risks from side-effects being small in comparison to the reduction in climate risks."
