Bednar, J.; et al. (2019): Field Grand Challenge: Negative Emission Technologies

Bednar, J.; Obersteiner, M.; Wagner, F. (2019): On the financial viability of negative emissions. In: Nat Comms 10 (1), S. 1783. DOI: 10.1038/s41467-019-09782-x.

"The United Nations painted a dire picture of humanity’s future in its recent climate report (IPCC 2018). It warned that failing to act on carbon dioxide (CO2) emissions will lead to vanishing sea ice and melting glaciers, increased storm events, and ports and islands at risk due to rising sea levels. The report was sobering to many, but not to scientists tasked with developing solutions to climate change."

The Economist: Political economy suggests that geoengineering is likely to be used

"A much warmer and more hostile climate might yet be avoided, however, through geoengineering: tinkering with climate processes to reduce the global temperature. [...] The longer climate targets are missed, the more likely geoengineering is to be used—and the more urgent it is that governments understand its tricky political economy."

Los Angeles Times: The real climate change controversy: Whether to engineer the planet in order to fix it

"Most climate experts agree that the best way to keep global temperatures in check is to rapidly reduce emissions of carbon dioxide and other greenhouse gases by transitioning to clean energy sources. But scientists and policymakers are deeply divided over which forms of geoengineering also deserve serious consideration — and when the world might want to use them."

Digital Trends: Climeworks wants to clean the atmosphere with a fleet of truck-sized vacuums

"Engineers at Climeworks think they have a solution. Using machines that resemble jet engines, the Swiss startup wants to extract CO2 from thin air. From there, the gas can be siphoned off and sold to carbonated drink companies as fizz for sodas and agriculture companies as fuel for crops. Climeworks already has a deal with Coca-Cola, and it pipes CO2 to a greenhouse that grows tomatoes and cucumbers adjacent to its flagship plant in Hinwil, Switzerland."

The Conversation: New CO₂ capture technology is not the magic bullet against climate change

"According to a recent major UN report, if we are to limit temperature rise to 1.5 °C and prevent the most catastrophic effects of climate change, we need to reduce global CO₂ emissions to net zero by 2050. This means eliminating fossil fuel use fast – but to cushion that transition and offset the areas in which there is currently no replacement for combustibles, we need to actively remove CO₂ from the atmosphere. Planting trees and rewilding are a large part of this solution, but we are highly likely to need further technological assistance if we are to prevent climate breakdown. "

CBSnews: Capturing carbon, once a fringe idea, may be key to fighting climate change (video)

"Despite decades of warnings from climate scientists, the world is still struggling to cut down its CO2 emissions, the main driver of climate change. But a handful of researchers and private companies are trying to fill in some of the gaps with an idea that was once considered fringe: capturing carbon."
