Stenzel, F.; et al. (2019): Freshwater requirements of large-scale bioenergy plantations for limiting global warming to 1.5 °C

Stenzel, F.; Gerten, D.; Werner, C.; Jägermeyr, J. (2019): Freshwater requirements of large-scale bioenergy plantations for limiting global warming to 1.5 °C. In: Environ. Res. Lett. 14 (8), S. 84001. DOI: 10.1088/1748-9326/ab2b4b.

"This paper provides a first-order quantification of the biophysical potentials of BECCS as a negative emission technology contribution to reaching the 1.5 °C warming target, as constrained by associated water availabilities and requirements. Using a global biosphere model, we analyze the availability of freshwater for irrigation of BPs designed to meet the projected NEs to fulfill the 1.5 °C target, spatially explicitly on areas not reserved for ecosystem conservation or agriculture."

CarbonBrief: Direct CO2 capture machines could use ‘a quarter of global energy’ in 2100

"Machines that suck CO2 directly from the air could cut the cost of meeting global climate goals, a new study finds, but they would need as much as a quarter of global energy supplies in 2100."

Realmonte, G.; et al. (2019): An inter-model assessment of the role of direct air capture in deep mitigation pathways

Realmonte, G.; Drouet, L.; Gambhir, A.; Glynn, J.; Hawkes, A.; Köberle, A.; Tavoni, M. (2019): An inter-model assessment of the role of direct air capture in deep mitigation pathways. In: Nat Comms 10 (1), S. 3277. DOI: 10.1038/s41467-019-10842-5.

"The feasibility of large-scale biological CO2 removal to achieve stringent climate targets remains unclear. Direct Air Carbon Capture and Storage (DACCS) offers an alternative negative emissions technology (NET) option. Here we conduct the first inter-model comparison on the role of DACCS in 1.5 and 2 °C scenarios, under a variety of techno-economic assumptions."

The Japan Times: Scientists' 'terrible' idea calls for snow cannons to pump ice in bid to save Antarctic ice shelf

"Scientists seeking to avoid catastrophic sea-level rises from the melting West Antarctic ice sheet have come up with a 'terrible' solution: use snow cannons to pump trillions of tons of ice back on top."

Feldmann, J.; et al. (2019): Stabilizing the West Antarctic Ice Sheet by surface mass deposition

Feldmann, J.; Levermann, A.; Mengel, M. (2019): Stabilizing the West Antarctic Ice Sheet by surface mass deposition. In: Science Advances 5 (7), eaaw4132. DOI: 10.1126/sciadv.aaw4132.

"There is evidence that a self-sustaining ice discharge from the West Antarctic Ice Sheet (WAIS) has started, potentially leading to its disintegration. The associated sea level rise of more than 3m would pose a serious challenge to highly populated areas including metropolises such as Calcutta, Shanghai, New York City, and Tokyo. Here, we show that the WAIS may be stabilized through mass deposition in coastal regions around Pine Island and Thwaites glaciers."

Geoengineering Monitor: Direct Air Capture: Recent developments and future plans

"In the early 1990s, the European Space Agency launched a technology to extend space missions by filtering exhaled CO2 out of the air on board of shuttles and space stations. During the past two decades, the technology – known as Direct Air Capture (DAC) – has been further developed, but in a different context: researchers are considering the technology as a means to remove CO2 or other greenhouse gases from the earth’s atmosphere."
