The Guardian: Radical plan to artificially cool Earth's climate could be safe, study finds

"A new study contradicts fears that using solar geoengineering to fight climate change could dangerously alter rainfall and storm patterns in some parts of the world."

Irvine, P.; et al. (2019): Halving warming with idealized solar geoengineering moderates key climate hazards

Irvine, P.; Emanuel, K.; He, J.; Horowitz, L.; Vecchi, G.; Keith, D. (2019): Halving warming with idealized solar geoengineering moderates key climate hazards. In: Nature Climate change. DOI: 10.1038/s41558-019-0398-8.

"Solar geoengineering (SG) has the potential to restore average surface temperatures by increasing planetary albedo, but this could reduce precipitation. Thus, although SG might reduce globally aggregated risks, it may increase climate risks for some regions. Here, using the high-resolution forecast-oriented low ocean resolution (HiFLOR) model—which resolves tropical cyclones and has an improved representation of present-day precipitation extremesalongside 12 models from the Geoengineering Model Intercomparison Project (GeoMIP), we analyse the fraction of locations that see their local climate change exacerbated or moderated by SG. Rather than restoring temperatures, we assume that SG is applied to halve the warming produced by doubling CO2 (half-SG)."

Project Syndicate: Governing Geoengineering

"New technologies to combat global warming could complement reductions in greenhouse-gas emissions. But their potential impact is highly uncertain, and failure to govern their use properly could aggravate existing threats to international peace and security."

Call for Sessions: Securing sustainable futures. Designing, planning, and making decisions on policies, practices, and infrastructures under deep uncertainty

Deadline: 1. April 2019

"We are now inviting proposals for sessions related to the theme of ‘Securing sustainable futures’. Session proposals can focus on specific methods or approaches and how these are or could be used across different application domains, or instead focus on the treatment of deep uncertainty within a specific domain or context."

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

"Geoengineering – large-scale intentional manipulation of the Earth’s natural systems such as oceans, lands, atmosphere and carbon cycles – is increasingly being presented as a strategy to counteract, dilute or delay climate change and its effects. The UN Environment Assembly (UNEA) is expected to address the issue at its fourth session, convening in Nairobi, Kenya, from 11-15 March 2019, and should do so with caution."

Chatham House: Cool idea or hi-tech madness?

"As the threat from climate change looms ever larger, growing attention is being paid to proposals that sound as if they come straight from a sci-fi novel. One idea is to spray the stratosphere with particulates to reflect sunlight, thus reducing the temperature of planet Earth."

Legal Planet: Does the Fossil Fuel Industry Support Geoengineering?

"Geoengineering is controversial in the climate change community, and understandably so. Proposed interventions like negative emissions technologies (a.k.a. carbon dioxide removal) and solar geoengineering (a.k.a. solar radiation management or SRM) involve large-scale intervention in the climate system that could have adverse physical or social impacts. At the same time, some geoengineering methods could substantially reduce climate change."

Project Syndicate: Geoengineering is a Dangerous Distraction

"A growing number of people are now considering the once-unthinkable strategy of geoengineering our way out of the climate crisis. Proposed approaches vary widely, but all share a few key features: they are technologically uncertain, environmentally risky, and more likely to accelerate the climate crisis than to reverse it."

Khaleej Times: Tampering with the weather could end in disaster

"To avoid crossing the 1.5°C threshold, the world must nearly halve its CO2 emissions by 2030, and reach net zero emissions by 2050. This will be possible only if we completely eliminate fossil fuels from the economy within the next few decades. Attempts to circumvent that reality will only make matters worse. We're at risk of doing just that. A growing number of people are now considering the once-unthinkable strategy of geoengineering our way out of the climate crisis."
