Cox, E.; et al. (2019): Beyond carbon pricing: policy levers for negative emissions technologies

Cox, E.; Edwards, N. (2019): Beyond carbon pricing: policy levers for negative emissions technologies. In: Climate Policy 6 (38), p. 1–13. DOI: 10.1080/14693062.2019.1634509.

„This paper explores policies for Negative Emissions Technologies (NETs), in an attempt to move beyond the supply-side focus of the majority of NETs research, as well as the current dominance of carbon pricing as the main NETs policy proposal. The paper identifies a number of existing policies from four key areas[nbsp]– energy/transport, agriculture, sub-soil, and oceans[nbsp]– which will have an impact on three NETs: Bioenergy with Carbon Capture and Storage (BECCS), Direct Air Capture (DAC), and terrestrial Enhanced Rock Weathering (ERW).“

Bock, L.; et al. (2019): Contrail cirrus radiative forcing for future air traffic

Bock, L.; Burkhardt, U. (2019): Contrail cirrus radiative forcing for future air traffic. In: Atmos. Chem. Phys 19 (12), S. 8163–8174. DOI: 10.5194/acp-19-8163-2019.

„The climate impact of air traffic is to a large degree caused by changes in cirrus cloudiness resulting from the formation of contrails. Contrail cirrus radiative forcing is expected to increase significantly over time due to the large projected increases in air traffic. We use ECHAM5-CCMod, an atmospheric climate model with an online contrail cirrus parameterization including a microphysical two-moment scheme, to investigate the climate impact of contrail cirrus for the year 2050.“

Schubert, J. (2019): Measuring, Modeling, Controlling the Climate? Numerical Expertise in U.S. Climate Engineering Politics

Schubert, J. (2019): Measuring, Modeling, Controlling the Climate? Numerical Expertise in U.S. Climate Engineering Politics. In: Markus J. Prutsch (Hg.): Science, Numbers and Politics. Cham: Palgrave Macmillan US, p. 181–201.

„This contribution explores the role of quantified scientific expertise for U.S. geoengineering politics. Drawing on empirical evidence from federal proceedings, it assesses how climate measures, models, targets, and thresholds have shaped the trajectory of geoengineering within U.S. climate policy between 1990 and 2015.“

Huffpost: A Longshot 2020 Candidate Wants To Push Geoengineering Into The Climate Debate

Geoengineering is a catch-all term for technologies that could counter the effects of global warming. Ideas range from the relatively benign, like sucking carbon dioxide out of the atmosphere; to the quirky, like building berms at the base of Arctic glaciers to slow melting from the warming ocean; to the radical, such as solar radiation management, which involves spraying sulfur gases into the atmosphere to reflect the sun’s warming rays back into space.

Carbon Engineering: Government of Canada invests $25m in clean energy technology that creates fuel from air

„The Honourable Jonathan Wilkinson, Minister of Fisheries, Oceans, and the Canadian Coast Guard, today announced an investment of CAN$25 million in Carbon Engineering Ltd. (CE), a Canadian clean energy company that is pioneering technologies to capture and reuse carbon dioxide (CO2) from the atmosphere. This announcement highlights Canada’s continuing support for home-grown cleantech innovations and signifies the government’s commitment to deploy technologies that support the transition to a low carbon economy. It follows the company’s recently completed private investment round of CAN$91 million.“

Gunderson, R.; et al. (2019): Materialized ideology and environmental problems: The cases of solar geoengineering and agricultural biotechnology

Gunderson, R.; Stuart, D.; Petersen, B. (2019): Materialized ideology and environmental problems: The cases of solar geoengineering and agricultural biotechnology. In: European Journal of Social Theory 57 (3), 136843101983925. DOI: 10.1177/1368431019839252.

„This article expands upon the notion of ideology as a material phenomenon, usually in the form of institutionalized, taken-for-granted practices. It draws on Herbert Marcuse and related thinkers to conceptualize technological solutions to environmental problems as materialized ideological responses to social-ecological contradictions, which, by concealing these contradictions, reproduce existing social conditions.“
