MyStatesman: Commentary: The climate crisis will not be solved by technology alone

"Optimism needs to be distinguished from hope. Much of the optimism surrounding climate change is dominated by technological imaginaries and proposals such as geoengineering the planet through solar radiation management."

Hemes, Kyle S.; et al. (2018): A Biogeochemical Compromise. The High Methane Cost of Sequestering Carbon in Restored Wetlands

Hemes, Kyle S.; Chamberlain, Samuel D.; Eichelmann, Elke; Knox, Sara H.; Baldocchi, Dennis D. (2018): A Biogeochemical Compromise. The High Methane Cost of Sequestering Carbon in Restored Wetlands. In: Geophys. Res. Lett. 121 (8), S. 777. DOI: 10.1029/2018GL077747.

"Here we present 14 site years of continuous CH4 and CO2 ecosystem‐scale gas exchange over a network of restored freshwater wetlands in California, where long growing seasons, warm weather, and managed water tables result in some of the largest wetland ecosystem CH4 emissions recorded. These large CH4 emissions cause the wetlands to be strong greenhouse gas sources while sequestering carbon and building peat soil. The terms of this biogeochemical compromise, dictated by the ratio between carbon sequestration and CH4 emission, vary considerably across small spatial scales, despite nearly identical wetland climate, hydrology, and plant community compositions."

Popular Mechanics: NASA Is Stepping Into the Twilight Zone

"Tiny ocean plankton pull carbon dioxide out of the air during photosynthesis and stash it in the deeper ocean when they die. NASA scientists want to study this "twilight zone" when the CO2 ends up to better understand how tiny organisms affect climate change. They're taking two boats rigged with scientific equipment to the Pacific Ocean to study the twilight zone."

Project ongoing: Reviewing the potential impacts of geoengineering on ecosystems and biodiversity

Project by University of Cambridge and UNEP / WCMC. "Work on this review is ongoing, and it will provide a very useful reference guide for those seeking to research or respond to developments in geoengineering. It will also help people to access the latest information on twenty of the geoengineering techniques currently being discussed and their potential positive or negative impacts on biodiversity."
