Newcastle Herald: Negative emissions technology and global warming

"To avoid 2 degrees average global warming before 2100, widespread negative emissions technologies that remove CO2 from the air need to start by 2030 – in 11 years – ramping up to global net negative emissions by 2070."

Peter Frase Blog: Geoengineering for the people

"The first issue of the group’s revived publication concerns geoengineering, an issue on which I’ve thrown in my own two cents. The prospect of directly attempting to manipulate the earth’s climate, in order to mitigate the effects of climate change, has begun to seem more and more like a reality, and perhaps a necessity. So an intervention from scientists with solid leftist politics is timely and urgent."

Techradar: Could geoengineering be used to manage our climate?

"This is geoengineering, a range of complex and controversial techniques that are set to one day be used to tinker with global weather systems."

Pawlok, D.; et al. (2018): Grasslands may be more reliable carbon sinks than forests in California

Pawlok, D.; Houlton, B. Z.; Wang, Y.; Warlind, D. (2018): Grasslands may be more reliable carbon sinks than forests in California. In: Environ. Res. Lett. 13 (7), S. 74027. DOI: 10.1088/1748-9326/aacb39.

"Using a set of modeling experiments, we show that California grasslands are a more resilient C sink than forests in response to 21st century changes in climate, with implications for designing climate-smart Cap and Trade offset policies. The resilience of grasslands to rising temperatures, drought and fire, coupled with the preferential banking of C to belowground sinks, helps to preserve sequestered terrestrial C and prevent it from re-entering the atmosphere."

Mueller, B. L.; et al. (2018): Attribution of Arctic sea ice decline from 1953 to 2012 to influences from natural, greenhouse-gas and anthropogenic aerosol forcing

Mueller, B. L.; Gillett, N. P.; Monahan, A. H.; Zwiers, F. W. (2018): Attribution of Arctic sea ice decline from 1953 to 2012 to influences from natural, greenhouse-gas and anthropogenic aerosol forcing. In: J. Climate. DOI: 10.1175/JCLI-D-17-0552.1.

"We show that fingerprints from greenhouse-gas, natural and other anthropogenic forcings are detected in the three observed records of Arctic sea ice extent. Beyond that, our findings indicate that for the 1953 to 2012 period roughly 23% of the greenhouse-gas induced negative sea ice trend has been offset by a weak positive sea ice trend attributable to other anthropogenic forcing. We show that our detection and attribution results remain robust in the presence of emerging non-stationary internal climate variability acting upon sea ice using a perfect model experiment and data from two large ensembles of climate simulations."

The Guardian: Pollution is slowing the melting of Arctic sea ice, for now

"The authors concluded that the combined cooling effect from human aerosols was detected in all three datasets of ice. That means, it didn’t matter whose measurements you used – the effect of aerosol cooling was present."
