Job: PhD student with a degree in physics, chemistry, environmental sciences or a related field for a three-year position. Topic: Stratospheric Ozone Loss in Midlatitudes in Summer − a Potential Risk of Climate Engineering?

Deadline: 30. September 2016

"We are seeking a new Ph.D. student (physics, chemistry, environmental sciences) in the ''Theory'' group (with the focus on numerical simulations of chemical and physical processes in the atmosphere). The Ph.D. project is part of the DFG Priority Program 'Climate Engineering: Risks, Challenges, Opportunities?'. The Ph.D. work will be performed within a three-year program of the Graduate School HITEC."

Mashable: Geoengineering is a bonkers plan, but it may be needed to tackle global warming

"Solar geoengineering is nuts. That, at least, is the reaction of many who hear about it for the first time. And how can it not be? Serious scientists are talking about deliberately trying to reflect a small fraction of sunlight back to space in order to cool planet Earth. But calling it ‘nuts’ is beside the point. The real question is: nuts compared to what?"

Vaughan, Naomi E.; Gough, Clair (2016): Expert assessment concludes negative emissions scenarios may not deliver

Vaughan, Naomi E.; Gough, Clair (2016): Expert assessment concludes negative emissions scenarios may not deliver. In Environ. Res. Lett. 11 (9), pp. 1–7. DOI 10.1088/1748-9326/11/9/095003.

"Here we present the results of an expert elicitation process that explores the explicit and implicit assumptions underpinning the feasibility of BECCS in IAM scenarios. Our results show that the assumptions are considered realistic regarding technical aspects of CCS but unrealistic regarding the extent of bioenergy deployment, and development of adequate societal support and governance structures for BECCS."

Rockström, Johan; et al. (2016): The world's biggest gamble

Rockström, Johan; Schellnhuber, Hans Joachim; Hoskins, Brian; Ramanathan, Veerabhadran; Schlosser, Peter; Brasseur, Guy Pierre et al. (2016): The world's biggest gamble. In Earth's Future. DOI 10.1002/2016EF000392 .

"Only a global zero carbon roadmap will put the world on a course to phase-out greenhouse gas emissions and create the essential carbon sinks for Earth-system stability, without which, world prosperity is not possible. [...] Therefore, we will focus here on conventional carbon capture and storage (CCS), bioenergy with carbon capture and storage (BECCS), and biosphere carbon uptake through sustainable land management practices."

Schrogl, K.-U.; Summerer, L. (2016): Climate engineering and space

Schrogl, K.-U.; Summerer, L. (2016): Climate engineering and space. In Acta Astronautica. DOI 10.1016/j.actaastro.2016.08.033 

"The article describes these currently discussed measures for such climate engineering. It will particularly analyse the expected contributions from space to these concepts. Based on this it evaluates the economic and political implications and finally tests the conformity of these concepts with space law."

Science Daily: Seeing the forest for the trees: World's largest reforestation program overlooks wildlife

"New research found that China's reforestation program, the world's largest, overwhelmingly leads to the planting of monoculture forests that fall short of restoring the biodiversity of native forests -- and can even harm existing wildlife. The researchers found, however, that multi-species forests could be planted without detracting from the economic benefits China's poor and rural citizens receive for replanting forests."

Forest News: Q & A: Lessons from Ethiopia for forest landscape restoration

"An interview with CIFOR Scientist Habtemariam Kassa. [...] Every year trees are planted, but nobody comes and looks at their survival rate – and in fact our quick assessment indicated that trees planted by smallholder framers themselves on their own land had a much higher survival rates while tree planted through state-led tree planting campaigns showed very low survival rates."

UCAR Atmos News: The 2-degree goal and the question of geoengineering

Response to Tilmes, S.; et al. (2016). "In a new study, the scientists found that if society doesn't make steep cuts in greenhouse gas emissions in the next couple of decades, injections of planet-cooling sulfates into the atmosphere could theoretically limit warming to 2 degrees Celsius (3.6 degrees Fahrenheit) above preindustrial levels. But such geoengineeing would mean a sustained effort stretching over more than a century and a half, and it would fail to prevent certain aspects of climate change."
