Axios: We asked five experts about engineering the climate

"What do we need to know before someone pushes start on a large-scale geoengineering attempt? And what Earth-altering experiment should we try first? Five leading researchers answered those questions and gave us their take on the risks, as well as the thorny ethical and legal issues that come with unleashing a technology that could span countries, cultures, and generations."

Reuters: Reversing climate change with carbon-sucking plantations not realistic, scientists warn

On Boysen et al. (2017). "A proposal to turn back climate change by planting vast swathes of land with fast-growing trees and plants that can be burned for electricity, with the carbon they release captured and stored, is not “realistic and feasible”, scientists said Thursday. The idea, included in many economic and science models on how the world might try to reverse runaway climate change, cannot serve as an emergency back-up if the world fails to rapidly switch from fossil fuels to renewable energy and then regrets the consequences, said scientists at the Potsdam Institute for Climate Impact Research in Germany."

Boysen, Lena R.; et al. (2017): The limits to global-warming mitigation by terrestrial carbon removal

Boysen, Lena R.; Lucht, Wolfgang; Gerten, Dieter; Heck, Vera; Lenton, Timothy M.; Schellnhuber, Hans Joachim (2017): The limits to global-warming mitigation by terrestrial carbon removal. In: Earth's Future 4, S. 514. DOI: 10.1002/2016EF000469 

"Massive near-term greenhouse gas emissions reduction is a precondition for staying “well below 2°C” global warming as envisaged by the Paris Agreement. Furthermore, extensive terrestrial carbon dioxide removal (tCDR) through managed biomass growth and subsequent carbon capture and storage is required to avoid temperature “overshoot” in most pertinent scenarios."

Sandler, Todd (2017): Collective action and geoengineering

Sandler, Todd (2017): Collective action and geoengineering. In: Rev Int Organ 39 (1), S. 45. DOI: 10.1007/s11558-017-9282-3

"This paper investigates some of the myriad collective action implications of geoengineering. Its two major components – carbon dioxide reduction and albedo modification – present diverse collective action and strategic aspects. Carbon dioxide reduction may be characterized by Prisoners’ Dilemma, threshold, or harmony games, depending on capture and sequestration procedures. In contrast, albedo modification may abide by chicken, coordination, or threshold games."

IASS Blog: Stop shaming geo-engineering researchers!

"Environmentalists are often critical of technological fixes problems caused by technology. But when it comes to geo-engineering, a clear distinction needs to be made between the message and the messenger."

Mobi Picker: Negative Emissions Technology May Solve Climate Change, But It’s Not Going To Be A Cakewalk For Sure

"Worth noting, as the carbon dioxide in the atmosphere reaches 400 parts per million for the first ever time in human history, some scientists and environmentalists are also pondering over the idea of directly capturing carbon dioxide from the atmosphere using huge versions of atmospheric scrubbers designed to remove CO2 from the air above and around us on board spacecraft."
