Harvard John A. Paulson School of Engineering and Applied Sciences: Finding the right "dose" for solar geoengineering (Video)

"Research from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), in collaboration with MIT and Princeton University, finds that if solar geoengineering is used to cut global temperature increases in half, there could be worldwide benefits without exacerbating change in any large geographic area."

Mirror: Spraying chemicals into the atmosphere to DIM THE SUN could halve global warming

"A bizarre plan to mitigate climate change by spraying chemicals into the atmosphere to "turn down the sun" could actually work."

Arabnews: Time is right to lay down rules on geoengineering

"Although reducing greenhouse gas emissions must remain the highest priority, the UN Intergovernmental Panel on Climate Change (IPCC) says this is not enough. Some now suggest that we also need to remove huge amounts of carbon dioxide from the air. Others argue that we may also need to reflect sunlight back into space to buy the world more time to reduce and remove emissions."

VOANews: Governments Seek UN Scrutiny of Technologies to Cool the Climate

"As climate change accelerates, the United Nations Environment Assembly will this week consider whether to start assessing, and setting rules on, technologies that could pull carbon out of the atmosphere or block some of the sun's warmth to cool the Earth."

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)."

Dailymail Online: Is this the solution to global warming? Artificially cooling the Earth's atmosphere by spraying chemicals into the air could halve temperature rises from climate change, study says

"Artificially cooling Earth by injecting aerosols into the atmosphere could be a viable and safe option in combating global warming, despite fears it could cause huge monsoons around the world."
