Vox: Bali’s fiery volcano could end up temporarily cooling the entire planet

"Scientists are also toying with the controversial idea of imitating volcanoes to keep global warming in check, a strategy known as geoengineering. This includes deliberately seeding clouds or spraying sulfuric acid into the stratosphere to offset some of humanity’s impacts on the world’s climate. "

CNN: Far-fetched fixes for climate change, from solar shields to air-scrubbing

"In the battle against climate change, efforts to reduce emissions of harmful gases like carbon dioxide have consumed most of the headlines. But many scientists say that simply minimizing man-made pollution is not enough to limit global warming to two degrees Celsius, as agreed in the 2015 Paris climate agreement -- humans must also devise other means to help cool the planet. There's no shortage of imaginative proposals to achieve this goal. Some involve sucking carbon dioxide out of the atmosphere; others, including a giant space-based solar shield, would reduce the amount of sunlight that reaches Earth."

Reuters: Games offer familiar structures designed to allow us to play with the unfamiliar and rethink what is possible

"At a 2017 conference in Berlin, a dice-based game session explored potential governance mechanisms for geoengineering, the potential manipulation of the global climate by spreading sulphur in the stratosphere to block sunlight and cool the planet. When one participant tried to alter the climate, a remarkable range of reactions emerged from other individuals and teams -– from silent endorsement to self-sacrifice and even threat of nuclear war."

Jackson, R. B.; et al. (2017): Focus on negative emissions

Jackson, R. B.; Canadell, J. G.; Fuss, S.; Milne, J.; Nakicenovic, N.; Tavoni, M. (2017): Focus on negative emissions. In Environ. Res. Lett. 12 (11), p. 110201. DOI: 10.1088/1748-9326/aa94ff.

" One option increasingly invoked in integrated assessment models (IAMs) is negative emissions, defined as the net removal of CO2 from the atmosphere. Two of the most commonly proposed alternatives are biomass energy with carbon capture and sequestration (BECCS) and direct air capture (DAC). However, little is known about the global potential of emerging and future negative emissions technologies, the sustainability and cost of large-scale deployment needed to meet "safe" climate stabilization targets, and the carbon-climate feedbacks of entering a new carbon-negative world. These knowledge-gaps are the focus of the proposed special issue: [...]"

Geden, Oliver; Löschel, Andreas (2017): Define limits for temperature overshoot targets

Geden, Oliver; Löschel, Andreas (2017): Define limits for temperature overshoot targets. In Nature Geosci 6, p. 827. DOI: 10.1038/s41561-017-0026-z.

"Temperature overshoot scenarios that make the 1.5 °C climate target feasible could turn into sources of political flexibility. Climate scientists must provide clear constraints on overshoot magnitude, duration and timing, to ensure accountability."

Bioenergy Insight: Bioenergy combined with CCS will help UK to transition to low-carbon energy economy, expert says

"Bioenergy technologies combined with carbon capture and storage (CCS) can play a significant role in the UK’s future UK energy system, according to Energy Technologies Institute (ETI) strategy manager for bioenergy Hannah Evans. The ETI is a UK-based company formed from global industries and the UK government. It was formed in 2007, but its programme is officially ending at the end of this year."

Ingenioren: Geoengineering can create hurricanes or drip on opposite hemisphere (Danish)

"Using aerosols as a sun shield can have catastrophic consequences in parts of the world unless both hemispheres of the earth are covered. It shows a new study published in Nature, which calls for immediate regulation to be introduced in this area." (Google Translate)

CEC17: Opening Event (Video)

"Due to the limited success of efforts to reduce greenhouse gas emissions, climate engineering (CE) has been increasingly studied in recent years. Often defined as intentional, large-scale interventions in the global climate to counteract some of the effects of climate change, climate engineering techniques continue to be the subject of contentious debate in different in political, scientific and cultural fora. Following the success of the first large international conference on climate engineering in 2014, the IASS and its partners hosted the Climate Engineering Conference 2017: Critical Global Discussions – in Berlin from 9 to 12 October 2017."
