Mandal, S.; et al. (2019): Transforming Atmospheric CO2 into Alternative Fuels. A Metal-Free Approach under Ambient Conditions

Mandal, S.; Sau, S.; Bhattacharjee, R.; Hota, P.; Vardhanapu, P.; vijaykumar, g. et al. (2019): Transforming Atmospheric CO2 into Alternative Fuels. A Metal-Free Approach under Ambient Conditions. In: Chem. Sci. DOI: 10.1039/C8SC03581D.

"The capture of CO2 from air can even proceed in the solid state via the formation of a bicarbonate complex (aNHC-H, HCO3, B(OH)3), which was also structurally characterized. A detailed mechanism for this process is proposed based on tandem density functional theory calculations and experiments."

ANU TV: 2018 Negative Emissions Conference (Videos)

"Earth is warming at an unprecedented rate due to anthropogenic carbon dioxide emissions. This was recognised at the 2015 Paris Climate Convention (COP21) in 2015 who agreed to limit warming at 2°C or less. Emission reductions are essential to help mitigate further warming, but we are already likely to exceed this 2°C warming. In response, COP21 recognised that some form of ‘negative emissions’ is required to stay within the 2°C warming target."

npr: How 1 Company Pulls Carbon From The Air, Aiming To Avert A Climate Catastrophe

"At a major climate meeting in Poland, nearly 200 countries are trying to reach a deal on dramatically reducing carbon emissions. But a recent U.N. report found that may not be enough to avoid dangerous impacts from the warming climate. In fact, the world is falling so far short of what's needed, it said, that it may be necessary to pull massive amounts of carbon dioxide out of the air."

Akademien der Wissenschaften Schweiz (2018): Reverse emissions or influence solar radiation: Is “geoengineering” worthwhile, feasible and if so, at what price?

Akademien der Wissenschaften Schweiz (2018): Reverse emissions or influence solar radiation: Is “geoengineering” worthwhile, feasible and if so, at what price? Swiss Academies Factsheets 13 (4). Doi: 10.5281/zenodo.1409025

"The aim of the Paris Agreement is to limit global warming to well below 2 degrees Celsius, if possible even 1.5 degrees Celsius. Various scenarios show that very great efforts are necessary to achieve these goals through emission reduction measures alone. This motivates the search for additional solutions. Technical interventions in the climatesystem, often referred to by collective terms such as “geoengineering” or “climate intervention”, are therefore discussed."

Independent: First ever sun-dimming experiment will mimic volcanic eruption in attempt to reverse global warming

"Scientists plan to mimic the effects of a massive volcanic eruption in a bid to tackle global warming. Plans to geoengineer the atmosphere by blocking out sunlight have been floated before, but an experiment launched next year by Harvard researchers will be the first to test the theory in the stratosphere."

Rissman, J. (2018): Cement's role in a carbon-neutral future

Rissman, J. (2018): Cement's role in a carbon-neutral future. November 2018. Energy Innovation. Online: https://docs.google.com/viewer?a=v&pid=forums&srcid=MDg3MzExNzQ5NTQ5MTYwODk5OTMBMTU1OTIzMzM1NTcwNDcwODA0MjgBa2x5SjhqS25CZ0FKATAuMQEBdjI&authuser=0.

"After its manufacture, cement naturally sequesters CO2 from the atmosphere in a process called
“carbonation.” Carbonation rates vary considerably with concrete properties, which differ by
world region. Globally, roughly a third of cement’s process emissions are re-absorbed within the
first two years, and over the course of decades, this share rises to 48%. Cement carbonation is
relevant on a global scale but has been omitted from national emissions inventories and global
estimates."

Green Faith: Playing God?

"As policymakers face the magnitude of the 1.5-degree challenge, new technologies and approaches for capping temperature increases—referred to as climate engineering or geoengineering—are under growing discussion."

New Security Beat: Panelists Call for Creation of World Commission to Handle Solar Radiation Management

"'Right now, it’s the Wild West in regard to governance with geoengineering,' said Paul Wapner, a professor at the School of International Service at American University at a recent panel about solar radiation management (SRM) at the Arizona State University’s Washington Center. According to the Governing Solar Radiation Management report which was the focus of the event, SRM, which theoretically would cool the planet by reflecting sunlight back into space, may be a viable last-resort option if climate change mitigation and adaptation efforts fail. Wapner said that 'there’s a danger in SRM, there’s a danger in climate change. And, balancing those risks is part of the exercise and will continue to be part of the exercise.'"
