Reef Trust Partnership (2019): Annual Work Plan 2019-2020

Reef Trust Partnership (2019): Annual Work Plan 2019-2020. Ed.: Australian Government, Reef Trust und Great Barrier Reef Foundation.

"The Great Barrier Reef is globally recognised as one of the seven natural wonders of the world and attracts over two million visitors each year. Australians are proud of the Reef and want to ensure that everything is being done to protect and restore our national icon. This is a defining moment for the Reef and this partnership is an unprecedented opportunity to drive the collaboration and action needed for the Great Barrier Reef, now and for the future."

Allgaier, J.: Science and Environmental Communication via Online Video: Strategically Distorted Communications on Climate Change and Climate Engineering on YouTube

Allgaier, J.: Science and Environmental Communication via Online Video: Strategically Distorted Communications on Climate Change and Climate Engineering on YouTube. In: Frontiers in Communication 2019. DOI: 10.3389/fcomm.2019.00036.

"The online video-sharing website YouTube is extremely popular globally, also as a tool for information on science and environmental topics. However, only little is known about what kind of information users find when they are searching for information about climate science, climate change and climate engineering on YouTube. This contribution presents results from an exploratory research project that investigates whether videos found on YouTube adhere to or challenge scientific consensus views."

Surprise, K. (2019): Stratospheric imperialism: Liberalism, (eco)modernization, and ideologies of solar geoengineering research

Surprise, K. (2019): Stratospheric imperialism: Liberalism, (eco)modernization, and ideologies of solar geoengineering research. In: Environment and Planning E: Nature and Space 38 (2), 251484861984477. DOI: 10.1177/2514848619844771.

"Once a fringe notion, solar geoengineering via Stratospheric Aerosol Injection (SAI) is gaining traction as a climate management tactic within mainstream institutions and factions of the climate justice movement. [...] In this context, I identify three dominant ideologies undergirding SAI research at Harvard—ecomodernism, Realist International Relations theory, and Keynesianism—that construct a specific narrative whereby established climate solutions (liberal-capitalist ecomodernism) are frustrated by “anarchical” international politics, leaving the poor vulnerable to near-term climate impacts."

Francaviglia, R.; et al. (2019): Assessing “4 per 1000” soil organic carbon storage rates under Mediterranean climate: a comprehensive data analysis

Francaviglia, R.; Di Bene, C.; Farina, R.; Salvati, L.; Vicente-Vicente, J. (2019): Assessing “4 per 1000” soil organic carbon storage rates under Mediterranean climate: a comprehensive data analysis. In: Mitig Adapt Strat Glob Change 24 (5), S. 795–818. DOI: 10.1007/s11027-018-9832-x.

"Soil Organic Carbon (SOC) is considered a proxy of soil health, contributing to food production, mitigation, and adaptation to climate change and other ecosystem services. Implementing Recommended Management Practices (RMPs) may increase SOC stocks, contributing to achieve the United Nations Framework Convention on Climate Change 21st Conference of the Parties agreements reached in Paris, France. In this framework, the “4 per 1000” initiative invites partners implementing practical actions to reach a SOC stock annual growth of 4‰."

Caves Rugenstein, J.; et al. (2019): Neogene cooling driven by land surface reactivity rather than increased weathering fluxes

Caves Rugenstein, J.; Ibarra, D.; Blanckenburg, F. von (2019): Neogene cooling driven by land surface reactivity rather than increased weathering fluxes. In: Nature 571 (7763), S. 99–102. DOI: 10.1038/s41586-019-1332-y.

"The long-term cooling, decline in the partial pressure of carbon dioxide, and the establishment of permanent polar ice sheets during the Neogene period have frequently been attributed to increased uplift and erosion of mountains and consequent increases in silicate weathering, which removes atmospheric carbon dioxide. However, geological records of erosion rates are potentially subject to averaging biases, and the magnitude of the increase in weathering fluxes—and even its existence—remain debated. "

Bastin, J.; et al. (2019): The global tree restoration potential

Bastin, J.; Finegold, Y.; Garcia, C.; Mollicone, D.; Rezende, M.; Routh, D. et al. (2019): The global tree restoration potential. In: Science (New York, N.Y.) 365 (6448), S. 76–79. DOI: 10.1126/science.aax0848.

"The restoration of forested land at a global scale could help capture atmospheric carbon and mitigate climate change. Bastin et al. used direct measurements of forest cover to generate a model of forest restoration potential across the globe (see the Perspective by Chazdon and Brancalion)."

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 – energy/transport, agriculture, sub-soil, and oceans – 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."
