The Conversation: COP24: here's what must be agreed to keep warming at 1.5°C

"The United Nations, in the IPCC Special Report on Global Warming of 1.5ºC has accepted that there isn’t any obvious pathway to zero emissions in such a short time frame, so they have pegged their hopes on NETs – Negative Emissions Technologies. These approaches include carbon capture and storage (CCS), which involves sucking CO₂ from the air and storing it deep underground."

ANU TV: 2018 Negative Emissions Conference (Videos)

"Earth is warming at an unprecedented rate due to anthropogenic carbon dioxide emissions. This was recognised at the 2015 Paris Climate Convention (COP21) in 2015 who agreed to limit warming at 2°C or less. Emission reductions are essential to help mitigate further warming, but we are already likely to exceed this 2°C warming. In response, COP21 recognised that some form of ‘negative emissions’ is required to stay within the 2°C warming target."

Gore, S.; et al. (2018): The potential environmental response to increasing ocean alkalinity for negative emissions

Gore, S.; Renforth, P.; Perkins, R. (2018): The potential environmental response to increasing ocean alkalinity for negative emissions. In: Mitig Adapt Strat Glob Change 47 (1), S. 199. DOI: 10.1007/s11027-018-9830-z.

"Increasing TA, however, did not significantly influence Corallina spp. primary productivity, respiration, or photophysiology. These results show that AOA may not be intrinsically detrimental for Corallina spp. and that AOA has the potential to lessen the impacts of ocean acidification. However, the experiment tested a single species within a controlled environment to constrain a specific unknown, the rate change of calcification, and additional work is required to understand the impact of AOA on other organisms, whole ecosystems, and the global carbon cycle."

Richter, R.; et al. (2018): Geoengineering. Sunlight reflection methods and negative emissions technologies for greenhouse gas removal

Richter, R.; Caillol, S.; Ming, T. (2018): Geoengineering. Sunlight reflection methods and negative emissions technologies for greenhouse gas removal. In: Letcher, T. (ed.): MANAGING GLOBAL WARMING. An interface of technology and human issues. [S.l.]: ELSEVIER ACADEMIC PRESS, p. 581–636.

"In order to keep global warming well below 2°C, the greenhouse gases emissions have to drastically drop by up to 70% till 2050, falling then to zero, and becoming negative by 2100. Negative emissions technologies or NETs are included in almost all scenarios of the integrated assessment models used by the Intergovernmental Panel on Climate Change to build the synthesis report that led to the Paris agreement. While intensive research is urgently needed to assess the numerous NETs proposed by scientists, others propose a technological fix to cool the Earth artificially and win time: those proposals are named geoengineering."

YaleEnvironment360:Climate Solutions: Is It Feasible to Remove Enough CO2 from the Air?

"Stephen Pacala, a professor of ecology and evolutionary biology at Princeton University, chaired the panel. In an interview with Yale Environment 360, he talks about why NETs are needed, what should be done to advance them, and why he believes that “direct air capture” technologies could come into widespread use within the next decade."

CarbonBrief: Guest post: Combining renewables with direct air capture for ‘net negative’ emissions

"The recent special report from the Intergovernmental Panel on Climate Change (IPCC) has shown that limiting global warming to 1.5C is still within reach, but that it requires rapid and stringent cuts to global CO2 emissions. Modelling pathways that achieve the Paris Agreement goals rely on swift decarbonisation of the power sector and scaling up of “negative emissions” – an array of techniques to remove CO2 from the atmosphere and store it on land or underground."

Forbes: Negative Emissions Won't Rescue Us From Climate Change

"The Intergovernmental Panel on Climate Change’s interim report on global warming, released earlier this month, is jarring stuff. It describes the extensive environmental and economic damage that will befall Earth as global warming approaches 1.5 degrees Celsius, even as we speed on a trajectory that will warm the planet twice as much by the end of this century."

Grist: The debate is over: We need to start sucking carbon from the air

"If we don’t suck carbon now, life will suck later. That’s the underlying theme of a report out Wednesday from the U.S. National Academy of Sciences. The 350-page paper looks at the prospects for carbon sucking — known to the fancy-talk types as 'negative emissions technologies.'"
