Mengis, N.; et al. (2019): Climate engineering–induced changes in correlations between Earth system variables—implications for appropriate indicator selection

Mengis, N.; Keller, D.; Rickels, W.; Quaas, M.; Oschlies, A. (2019): Climate engineering–induced changes in correlations between Earth system variables—implications for appropriate indicator selection. In: Climatic Change 104 (C7), S. 669. DOI: 10.1007/s10584-019-02389-7.

"Climate engineering (CE) deployment would alter prevailing relationships between Earth system variables, making indicators and metrics used so far in the climate change assessment context less appropriate to assess CE measures. Achieving a comprehensive CE assessment requires a systematic and transparent reevaluation of the indicator selection process from Earth system variables. Here, we provide a first step towards such a systematic assessment of changes in correlations between Earth system variables following simulated deployment of different CE methods."

MIT Technology Review: This alarmingly simple hack could let anyone tinker with the climate

"Adapting balloons into geoengineering devices may simply require mixing helium with a few kilograms of sulfur dioxide, a compound that in the stratosphere is converted into sulfuric acid, which in turn casts away heat. Pressure will build inside each balloon as it ascends, until it bursts somewhere above 20 kilometers (12 miles), scattering its contents into the atmosphere."

Belfer Center: Governance of the Deployment of Solar Geoengineering

"The Harvard Project on Climate Agreements has released a volume of 26 briefs that explores a range of topics related to how we might govern the deployment of solar geoengineering. “Solar geoengineering” (SG) refers to the deliberate alteration of the earth’s radiative balance in order to reduce the risks attributed to the accumulation of greenhouse gases in the atmosphere. The method most commonly discussed as technically plausible and potentially effective involves adding aerosols to the lower stratosphere, where they would reflect some (~1%) incoming sunlight back to space."

C2G2: Geoengineering: the need for governance. February 2019

"Geoengineering refers to a broad set of methods and technologies that aim to deliberately alter the climate system on a sufficiently large scale to alleviate the impacts of climate change. While definitions and terminology vary, in line with recent scientific consensus this paper gives separate consideration to the two main approaches considered as geoengineering: Solar Radiation Modification (SRM) and large-scale Carbon Dioxide Removal (CDR)."

MIT Technology Review: We’re about to kill a massive, accidental experiment in halting global warming

"Studies have found that ships have a net cooling effect on the planet, despite belching out nearly a billion tons of carbon dioxide each year. That’s almost entirely because they also emit sulfur, which can scatter sunlight in the atmosphere and form or thicken clouds that reflect it away.  In effect, the shipping industry has been carrying out an unintentional experiment in climate engineering for more than a century."

Khaleej Times: Tampering with the weather could end in disaster

"To avoid crossing the 1.5°C threshold, the world must nearly halve its CO2 emissions by 2030, and reach net zero emissions by 2050. This will be possible only if we completely eliminate fossil fuels from the economy within the next few decades. Attempts to circumvent that reality will only make matters worse. We're at risk of doing just that. A growing number of people are now considering the once-unthinkable strategy of geoengineering our way out of the climate crisis."
