Vox: Good news! Avoiding catastrophic climate change isn’t impossible yet. Just incredibly hard

"Even rapidly bringing our net greenhouse gas emissions down to zero probably won’t be enough to ensure that temperatures peak and begin falling before 2 C. To ensure that, we need to start sucking carbon back out of the atmosphere. We need to go carbon negative."

Climate Home: Did limiting warming to 1.5C just get easier?

"A new report has revised the ‘carbon budget’, apparently putting a 1.5C limit to warming within reach. But how useful is this measure? [...] The carbon budget concept is less useful for emission pathways, particularly with tight carbon budgets and given that it is possible to exceed the carbon budget using negative emissions."

Flegal, Jane A.; Gupta, Aarti (2017): Evoking equity as a rationale for solar geoengineering research? Scrutinizing emerging expert visions of equity

Flegal, Jane A.; Gupta, Aarti (2017): Evoking equity as a rationale for solar geoengineering research? Scrutinizing emerging expert visions of equity. In Int Environ Agreements 7 (5), p. 311. DOI: 10.1007/s10784-017-9377-6.

"This paper examines how notions of equity are being evoked by expert advocates of more research into solar geoengineering. We trace how specific understandings of equity figure centrally—although not always explicitly—in these expert visions. We find that understandings of equity in such ‘‘vanguard visions’’ are narrowly conceived as epistemic challenges, answerable by (more) scientific analysis."

Call for Participation: Advisory group members on mitigation deterrence

Deadline: 30. October 2017

"We are convening an advisory group to help us find good parallels, design credible scenarios for deliberation, and generally advise on how best to make the project useful in practice. We have identified a range of people from various climate stakeholders (from researchers to campaigners), but we are also holding two seats for self-nominating members of the public. If you are interested in the future of the climate, maybe as a parent, or even an activist, and could spare 8-10 hours over the next two years to join a series of virtual, on-line advisory meetings, we’d like to hear from you."

American Towns: Earth Talk: Geoengineering solutions to address climate woes

"Dear EarthTalk: Are there any realistic geoengineering solutions to our climate woes and why haven’t we started employing them yet? -- A.M.

Geoengineering our way out of the climate crisis is something so drastic that no one really wants to admit it might be our only hope."

Kemena, Tronje Peer; et al. (2017): Atmospheric feedbacks in North Africa from an irrigated, afforested Sahara

Kemena, Tronje Peer; Matthes, Katja; Martin, Thomas; Wahl, Sebastian; Oschlies, Andreas (2017): Atmospheric feedbacks in North Africa from an irrigated, afforested Sahara. In Clim Dyn 66, p. 57. DOI: 10.1007/s00382-017-3890-8.

"Here, we investigate changes in precipitation and circulation in response to Saharan large-scale afforestation and irrigation with NCAR’s CESM-WACCM Earth system model. Our model results show a Saharan temperature reduction by 6 K and weak precipitation enhancement by 267 mm/year over the Sahara."

ScienceDaily: New climate risk classification created to account for potential 'existential' threats

On Xu, Yangyang; Ramanathan, Veerabhadran (2017). "With these scenarios in mind, the researchers identified what measures can be taken to slow the rate of global warming to avoid the worst consequences, particularly the low-probability high-impact events. Aggressive measures to curtail the use of fossil fuels and emissions of so-called short-lived climate pollutants such as soot, methane and HFCs would need to be accompanied by active efforts to extract CO2 from the air and sequester it before it can be emitted. It would take all three efforts to meet the Paris Agreement goal to which countries agreed at a landmark United Nations climate conference in Nov 2015."
