Pisoft, Petr; et al. (2021): Stratospheric contraction caused by increasing greenhouse gases

Pisoft, Petr; Sacha, Petr; Polvani, Lorenzo M.; Añel, Juan Antonio; La Torre, L. de; Eichinger, Roland et al. (2021): Stratospheric contraction caused by increasing greenhouse gases. In Environ. Res. Lett. DOI: 10.1088/1748-9326/abfe2b.

„The layer in between, the stratosphere, has not been studied extensively with respect to changes of its global structure. Here we show that this atmospheric layer has contracted substantially over the last decades, and that the main driver for this are increasing concentrations of GHG.“

Available online at https://scholarlycommons.law.northwestern.edu/cgi/viewcontent.cgi?article=1307[&]context=nulr_online[&]fbclid=IwAR0kQGReczRbpsuRrn1WgZnh5QI2QwEsULw5irDYt1fBz-cCKoN6vtMY-as.

„Congress recently instructed the National Oceanic and Atmospheric Administration (NOAA) to investigate stratospheric aerosols, materials that could be injected in the atmosphere as a means of solar climate intervention. This action has been widely interpreted as the first-ever federal research project into solar geoengineering—proposals to slightly “dim the sun” to limit the harms of climate change. This Essay argues that NOAA should use its discretion to conduct a programmatic environmental assessment under the National Environmental Policy Act (NEPA) as an initial step in governing this research program.“
