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.'"

Harwatt, H. (2018): Including animal to plant protein shifts in climate change mitigation policy

Harwatt, H. (2018): Including animal to plant protein shifts in climate change mitigation policy. A proposed three-step strategy. In: Climate Policy 18, S. 1–9. DOI: 10.1080/14693062.2018.1528965.

"This outlook article outlines why animal to plant-sourced protein shifts should be taken up by the Conference of the Parties (COP), and how they could feature as part of countries’ mitigation commitments under their updated Nationally Determined Contributions (NDCs) to be adopted from 2020 onwards. The proposed framework includes an acknowledgment of ‘peak livestock’, followed by targets for large and rapid reductions in livestock numbers based on a combined ‘worst first’ and ‘best available food’ approach. Adequate support, including climate finance, is needed to facilitate countries in implementing animal to plant-sourced protein shifts."

Nature: Global warming will happen faster than we think

"Prepare for the “new abnormal”. That was what California Governor Jerry Brown told reporters last month, commenting on the deadly wildfires that have plagued the state this year. He’s right. California’s latest crisis builds on years of record-breaking droughts and heatwaves. [...] Such environmental disasters will only intensify. Governments, rightly, want to know what to do. Yet the climate-science community is struggling to offer useful answers."
