Robock, Alan. 2020: “Benefits and Risks of Stratospheric Solar Radiation Management for Climate Intervention (Geoengineering).” Spring Bridge Issue on Engineering and Climate Change (50/1).[nbsp]
“Even if it becomes possible, stratospheric geoengineering would come with benefits but also risks and concerns. Quantifying these benefits and risks requires more research.“
The following events from the CE News Calendar have been rescheduled or cancelled due to COVID-19 (state of week 13 of 2020):
„For two decades,[nbsp]Klaus Lackner has been fixated on trees and how they pull carbon dioxide from the air. What if, the Arizona State University engineering professor theorized, you could create a machine that worked like a tree—but a thousand times more efficiently—thereby reducing the effects of climate change?“
„These scientists and inventors set out to change the planet with these out-of-the-box ideas.“
„The concept of stratospheric aerosol geoengineering involves adding a layer of aerosol particles to the upper atmosphere to decrease climate changes due to greenhouse gases like carbon dioxide.“
„A study suggests solar geoengineering could work most effectively by trying to blunt half of expected global warming, rather than all of it.“

“Climate models predict that significant deployment of negative emissions technologies (NETs) will be needed to avoid warming beyond 1.5°C.“
„The Arbor Day Foundation hosted and participated in a large number of forestry events at the United Nations Climate Change Conference during the 25th[nbsp]Conference of the Parties (COP25)[nbsp]in Madrid, Spain.“

“Here, we show that there is likely to be a widespread and consistent increase in the global CCSF (ranging from + 9.8% (RCP4.5) to + 17.1% (RCP8.5)) over the period 1950–2100.“
„Coastal enhanced silicate weathering[nbsp](ESW) as a negative emissions technology (NET) is an approach that uses the[nbsp]natural process of silicate weathering[nbsp]for the removal of CO2[nbsp]from the atmosphere.“
