"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."

"For the rst time, the CE-driven eects 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."

"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."

"Stopping the flow of carbon dioxide into the atmosphere is not enough. It has to be sucked out, too"
