Green Left: US rejects climate action, plans geoengineering

"The Untied States is now the only country trying to undermine the Paris Agreement on climate change. While other countries are pledging to cut their emissions — often inadequately, but at least accepting the need — the US intends to raise them. Meanwhile, the US is taking a step forward on the geoengineering path. Geoengineering, specifically Solar Radiation Management (SRM), refers to large-scale human interventions into the Earth’s climate. These aim to cut the levels of solar radiation that reach the Earth’s surface to artificially cool the planet."

ABC Live: COP23 Warns Against Risks of Climate Engineering

"Climate Engineering, or climate intervention, is risky but needs to be explored as a supplement – not as a ‘Plan B’ – to greenhouse gas emissions reduction, said experts at the United Nations Climate Change Conference (COP23), in Bonn, Germany."

Ferrer-Gonzalez, Miriam (2017): Climate engineering by enhancement of ocean alkalinity: impacts on the Earth system and a comparison with solar radiation management

Ferrer-Gonzalez, Miriam (2017): Climate engineering by enhancement of ocean alkalinity: impacts on the Earth system and a comparison with solar radiation management. PhD Thesis. Edited by Universität Hamburg. Max-Planck-Institut für Meteorologie. Hamburg (Reports on Earth System Science, 193).

"For the rst time, the CE-driven e ects on the Earth system of large-scale AOA and SRM scenarios are consistently compared in a comprehensive Earth system model with interactive carbon cycle. Using the Max Planck Institute Earth
System Model (MPI-ESM) forced by fossil-fuel CO2 emissions, I explore the impacts of these CE methods on the global carbon uptake and ocean biogeochemistry. I design and run AOA scenarios that reduce atmospheric CO2 levels to the trajectory of the Representative Concentration Pathway (RCP) 4.5 in a high CO2 world following the RCP8.5 scenario."

Zomer, Robert J.; et al. (2017): Global Sequestration Potential of Increased Organic Carbon in Cropland Soils

Zomer, Robert J.; Bossio, Deborah A.; Sommer, Rolf; Verchot, Louis V. (2017): Global Sequestration Potential of Increased Organic Carbon in Cropland Soils. In Scientific reports 7 (1), p. 15554. DOI: 10.1038/s41598-017-15794-8.

"The importance of intensively cultivated regions such as North America, Europe, India and intensively cultivated areas in Africa, such as Ethiopia, is highlighted. Soil carbon sequestration and the conservation of existing soil carbon stocks, given its multiple benefits including improved food production, is an important mitigation pathway to achieve the less than 2 °C global target of the Paris Climate Agreement."

Reuters: Can carbon-sucking technologies hold back climate change?

"As the U.S. state of California tries to slash its climate-changing emissions by 40 percent by 2030 – and 80 percent by 2050 – it is looking at some unusual new technologies, beyond simply cutting its use of fossil fuels. A California company called Blue Planet is capturing carbon dioxide from a fossil fuel power plant and binding it to small rock particles, to produce the aggregate needed for concrete."

American Instiute of Physics: Geoengineering Research Receives Backing at House Science Committee Hearing

"Republican committee leaders expressed hope that geoengineering technologies could someday address climate change. Democratic members were more cautious, supporting research but emphasizing it should not be viewed as a substitute for emissions reductions or other approaches for combating climate change."
