Steffen, W.; et al. (2018): Trajectories of the Earth System in the Anthropocene. In: Proceedings of the National Academy of Sciences of the United States of America

Steffen, W.; Rockström, J.; Richardson, K.; Lenton, T. M.; Folke, C.; Liverman, D. et al. (2018): Trajectories of the Earth System in the Anthropocene. In: Proceedings of the National Academy of Sciences of the United States of America. DOI: 10.1073/pnas.1810141115.

"We explore the risk that self-reinforcing feedbacks could push the Earth System toward a planetary threshold that, if crossed, could prevent stabilization of the climate at intermediate temperature rises and cause continued warming on a “Hothouse Earth” pathway even as human emissions are reduced. Crossing the threshold would lead to a much higher global average temperature than any interglacial in the past 1.2 million years and to sea levels significantly higher than at any time in the Holocene. We examine the evidence that such a threshold might exist and where it might be. If the threshold is crossed, the resulting trajectory would likely cause serious disruptions to ecosystems, society, and economies."

C2G2: Breaking the Deadlock between Gaians and Prometheans

"While some people view geoengineering as a creative and responsible technological option that must be considered in the face of a climate emergency, critics see it as a hubristic attempt to gain full-scale mastery of the planet and play God."

Bond-Lamberty, B.; et al. (2018): Globally rising soil heterotrophic respiration over recent decades

Bond-Lamberty, B.; Bailey, V. L.; Chen, M.; Gough, C. M.; Vargas, R. (2018): Globally rising soil heterotrophic respiration over recent decades. In: Nature 560 (7716), S. 80–83. DOI: 10.1038/s41586-018-0358-x

"Here we use an updated global soil respiration database9 to show that the observed soil surface RH:RS ratio increased significantly, from 0.54 to 0.63, between 1990 and 2014 (P = 0.009). Three additional lines of evidence provide support for this finding. By analysing two separate global gross primary production datasets10,11, we find that the ratios of both RH and RS to gross primary production have increased over time."

Goldberg, David; et al. (2018): Geological storage of CO 2 in sub-seafloor basalt. The CarbonSAFE pre-feasibility study offshore Washington State and British Columbia

Goldberg, David; Aston, Lara; Bonneville, Alain; Demirkanli, Inci; Evans, Curtis; Fisher, Andrew et al. (2018): Geological storage of CO 2 in sub-seafloor basalt. The CarbonSAFE pre-feasibility study offshore Washington State and British Columbia. In: Energy Procedia 146, S. 158–165. DOI: 10.1016/j.egypro.2018.07.020.

"Sub-seafloor basalts are very common on Earth and enable CO2 mineralization as a long-term storage mechanism, permanently sequestering the carbon in solid rock form. Our project goals include the evaluation of this reservoir as an industrial-scale CO2 storage complex, developing potential source/transport scenarios, conducting laboratory and modeling studies to determine the potential capacity of the reservoir, and completing an assessment of economic, regulatory and project management risks."

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."
