Gasparini, Blaž; et al. (2020): To what extent can cirrus cloud seeding counteract global warming?

Gasparini, Blaž; McGraw, Zachary; Storelvmo, Trude; Lohmann, Ulrike (2020): To what extent can cirrus cloud seeding counteract global warming? In Environ. Res. Lett. DOI: 10.1088/1748-9326/ab71a3.

"Previous studies that analyzed modifications of cirrus clouds by seeding of ice nucleating particles showed large uncertainties in both cloud and surface climate responses, ranging from no effect or even a small warming to a globally averaged cooling of about 2.5°C. We use two general circulation models that showed very different responses in previous studies, ECHAM6-HAM and CESM-CAM5, to determine which radiative and climatic responses to cirrus cloud seeding in a 1.5 x CO2 world are common and which are not."

Courthouse News Service: House Tackles Nat-Sec Implications of Climate Manipulation

"Injecting the stratosphere with chemicals so that humans can alter the effects of climate change sounds like a scheme from a disaster flick. But as the Earth warms and endures the effects of rising seas, temperatures and storms, the intelligence community told Congress Wednesday that scenario is just one of many ethical climate quandaries the world will face in coming years."

Business Insider Deutschland: We’re altering the climate so severely that we’ll soon face apocalyptic consequences. Here are 11 last-ditch ways we could hack the planet to reverse that trend.

"Geoengineering is a term that refers to technology that can alter Earth's natural cycles to cool down the planet. It's being increasingly discussed as a potential way to address climate change. Putting mirrors in space, capturing carbon dioxide, and seeding clouds with particles are all ways of manipulating weather or the atmosphere. But some scientists and politicians think geoengineering could damage the planet or lead to war."
