Dailymail: Could dimming the sun save the Earth?

"The plan sounds like science fiction — but could be fact within a decade; every day more than 800 giant aircraft would lift millions of tonnes of chalk dust to a height of 12 miles above the Earth's surface and then sprinkle the lot high around the stratosphere. In theory, the airborne dust would create a gigantic sunshade, reflecting some of the Sun's rays and heat back into space, dimming those that get through and so protecting Earth from the worsening ravages of climate warming."

Call for Application: Gordon Research Conference: Climate Engineering

Deadline: 31. May 2020

"This conference focuses on better understanding the processes and impacts associated with radiation management. This includes processes specific to individual methods, the projected climate response and its uncertainties, and the impacts, including those in the developing world, as well as the engineering aspects and the design of research to address risk."

IPCC: Land is a Critical Resource, IPCC report says

"Land is already under growing human pressure and climate change is adding to these pressures. At the same time, keeping global warming to well below 2ºC can be achieved only by reducing greenhouse gas emissions from all sectors including land and food, the Intergovernmental Panel on Climate Change (IPCC) said in its latest report on Thursday."

Duan, L.; et al. (2019): Climate Response to Pulse Versus Sustained Stratospheric Aerosol Forcing

Duan, L.; Cao, L.; Bala, G.; Caldeira, K. (2019): Climate Response to Pulse Versus Sustained Stratospheric Aerosol Forcing. In: Geophys. Res. Lett., S. 1. DOI: 10.1029/2019GL083701.

"Solar geoengineering has been suggested as a potential means to counteract anthropogenic warming. Major volcanic eruptions have been used as natural analogues to large‐scale deployments of stratospheric aerosol geoengineering, yet difference in climate responses to these forcings remains unclear."

Science: Bioenergy not a climate cure-all, panel warns

"In the effort to keep the planet from reaching dangerous temperatures, a hybrid approach called BECCS (bioenergy with carbon capture and storage) has a seductive appeal. Crops suck carbon dioxide (CO2) from the atmosphere, power plants burn the biomass to generate electricity, and the emissions are captured in a smokestack and pumped underground for long-term storage."

Shi, X.; et al. (2019): Sorbents for Direct Capture of CO2 from Ambient Air

Shi, X.; Xiao, H.; Azarabadi, H.; Song, J.; Wu, X.; Chen, X.; Lackner, K. (2019): Sorbents for Direct Capture of CO2 from Ambient Air. In: Angewandte Chemie (International ed. in English). DOI: 10.1002/anie.201906756.

"The urgency to address global climate change induced by greenhouse gas emissions is growing. In particular, the rise in atmospheric CO2 levels is generating alarm. [...] This paper reviews major types of sorbents designed to capture CO2 from ambient air, which are categorized by sorption mechanism: physisorption, chemisorption, and moisture‐swing sorption."

Wu, Z.; et al. (2019): Biochar can mitigate methane emissions by improving methanotrophs for prolonged period in fertilized paddy soils

Wu, Z.; Song, Y.; Shen, H.; Jiang, X.; Li, B.; Xiong, Z. (2019): Biochar can mitigate methane emissions by improving methanotrophs for prolonged period in fertilized paddy soils. In: Environmental Pollution 253, S. 1038–1046. DOI: 10.1016/j.envpol.2019.07.073.

"Biochar application to fertilized paddy soils has been recommended as an effective countermeasure to mitigate methane (CH4) emissions, but its mechanism and effective duration has not yet been adequately elucidated. A laboratory incubation experiment was performed to gain insight into the combined effects of fresh and six-year aged biochar on potential methane oxidation (PMO) in paddy soils with ammonium or nitrate-amendment."

Nbcnews: This ice-making submarine would pop out bergs to help fight climate change

"From building floating cities and towering sea walls to erecting snow cannons in Antarctica to help replenish melting polar ice, scientists and urban planners have proposed all sorts of schemes to defend against rising seas — one of the most worrisome consequences of climate change."

Science: Bioenergy plantations could fight climate change—but threaten food crops, U.N. panel warns
