Forbes: Giant Floating Solar Farms Could Extract CO2 From Seawater, Producing Methanol Fuel

"Millions of floating islands, clustered together, that convert carbon dioxide to methanol fuel could help reduce the amount of green house gases in the atmosphere, according to researchers from Norway and Switzerland."

Asayama, S.; et al. (2019): Engineering climate debt: temperature overshoot and peak-shaving as risky subprime mortgage lending

Asayama, S.; Hulme, M. (2019): Engineering climate debt: temperature overshoot and peak-shaving as risky subprime mortgage lending. In: Climate Policy 33 (3), p. 1–10. DOI: 10.1080/14693062.2019.1623165.

"Whilst some view optimistically the strategic interdependence between SRM and CDR, we argue that this strategy comes with a risk of escalating ‘climate debt’. We explain our position using the logic of debt and the analogy of subprime mortgage lending. In overshoot and peak-shaving scenarios, the role of CDR and SRM is to compensate for delayed mitigation, placing the world in a double debt: ‘emissions debt’ and ‘temperature debt’."

Call for Abstracts: Solar Geoengineering Benefits and Risks: Modeling, Impacts, Analogs, Engineering, Ethics, and Governance (AGU 100)

Deadline: 31. July 2019

"With continued unabated increase of greenhouse gas emissions, it is increasingly unlikely that climate change can be limited to prevent significant impacts on society and the ecosystem. Therefore, interest in potential geoengineering schemes is increasing, including solar radiation management (SRM) methods. In this session, we invite abstracts that analyze benefits and side effects of different SRM approaches from global to local scales."

Hemingway, J.; et al. (2019): Mineral protection regulates long-term global preservation of natural organic carbon

Hemingway, J.; Rothman, D.; Grant, K.; Rosengard, S.; Eglinton, T.; Derry, L.; Galy, V. (2019): Mineral protection regulates long-term global preservation of natural organic carbon. In: Nature 570 (7760), S. 228–231. DOI: 10.1038/s41586-019-1280-6.

"The balance between photosynthetic organic carbon production and respiration controls atmospheric composition and climate. [...] Here we present a global dataset of the distributions of organic carbon activation energy and corresponding radiocarbon ages in soils, sediments and dissolved organic carbon. We find that activation energy distributions broaden over time in all mineral-containing samples."

Futurism: How Geoengineering Could Lead to World War III

"To help protect the planet, many experts argue in favor of geoengineering, or deliberately hacking the Earth by sequestering atmospheric carbon or blocking sunlight. But while these plans may be well-intentioned, reports Business Insider, any country that pursues them without other nations’ blessings could inadvertently start a global war."
