FCEA Blog: The Developing World and Climate Engineering: Unevenly Affected and Underrepresented

„Asian monsoons have become a poignant parable in climate engineering discourse. Theoretically envisioning the effects of climate engineering on monsoons encapsulates the diffuse and complex implications embedded in these emerging technologies. However, the thought exercise reveals just as much about the discourse concerning the technologies as they do the technologies themselves. Specifically, they reveal the relative absence of developing countries from the discussion.“

TechSwitch: Local weather Change Is Right here. It’s Time to Discuss About Geoengineering

„This raises the specter of geoengineering : issues like seeding the stratosphere with sulfur, or utilizing ice crystals to dissolve heat-trapping clouds. However geoengineering is a grimy phrase many local weather scientists and local weather coverage specialists keep away from, as a result of people meddling with nature does not have one of the best observe document. Which is why they are saying world leaders have to give you some guidelines about geoengineering ASAP, earlier than desperation over the approaching local weather disaster forces humanity to do one thing it’d properly remorse.“

Independent: Crystal invented that can turn thin air into fuel and fight global warming

„A “spongy” crystal that can turn thin air into fuel by extracting carbon dioxide has been developed by scientists. The researcher said the light-activated material was a “critical step” towards making a high-value fuel while at the same time reducing the amount of the greenhouse gas in the atmosphere. It works by turning carbon dioxide into carbon monoxide, which can be turned into a useful source of energy.“

Nalam, Aditya; et al. (2017): Effects of Arctic geoengineering on precipitation in the tropical monsoon regions

Nalam, Aditya; Bala, Govindasamy; Modak, Angshuman (2017): Effects of Arctic geoengineering on precipitation in the tropical monsoon regions. In Clim Dyn 41 (1), p.[nbsp]1738. DOI: 10.1007/s00382-017-3810-y.

„In this study, we investigate and quantify the implications of this ITCZ shift due to Arctic geoengineering for the global monsoon regions using the Community Atmosphere Model version 4 coupled to a slab ocean model. A doubling of CO2 from pre-industrial levels leads to a warming of ~6[nbsp]K in the Arctic region and precipitation in the monsoon regions increases by up to ~15%. In our Arctic geoengineering simulation which illustrates a plausible latitudinal distribution of the reduction in sunlight, an addition of sulfate aerosols (11[nbsp]Mt) in the Arctic stratosphere nearly offsets the Arctic warming due to CO2 doubling but this shifts the ITCZ southward by ~1.5° relative to the pre-industrial climate.“

Reuters: Scientists dim sunlight, suck up carbon dioxide to cool planet

„Scientists are sucking carbon dioxide from the air with giant fans and preparing to release chemicals from a balloon to dim the sun’s rays as part of a climate engineering push to cool the planet. Backers say the risky, often expensive projects are urgently needed to find ways of meeting the goals of the Paris climate deal to curb global warming that researchers blame for causing more heatwaves, downpours and rising sea levels.“

INGOV: Workshop Update: The politics and governance of negative emissions technology

„To that end, the INOGOV COST Action supported* a workshop on “The Politics and Governance of Negative Emissions Technologies: Between the Paris Agreement and the Anthropocene,” which took place in June at the Utrecht University School of Law in the historic center of Utrecht, The Netherlands. The objective was to bring together diverse European scholars in the social sciences to deepen the understanding of the challenges and opportunities of NETs’ research, development, and possible implementation. Twenty-nine participants from six countries made the workshop a success in achieving this goal.“
