Horton, Joshua B.; et al. (2016): Implications of the Paris Agreement for Carbon Dioxide Removal and Solar Geoengineering

Horton, Joshua B.; Keith, David W.; Honegger, Matthias (2016): Implications of the Paris Agreement for Carbon Dioxide Removal and Solar Geoengineering. Belfer Center for Science and International Affairs, Harvard Kennedy School (Policy Briefs).

"We survey the implications of the revamped climate policy regime for carbon removal and solar geoengineering, hereafter referred to using the common acronyms carbon dioxide removal (CDR) and solar radiation management (SRM)."

Sharma, A.; et al. (2016): Green and cool roofs to mitigate urban heat island effects in the Chicago metropolitan area. Evaluation with a regional climate model

Sharma, A.; Conry, P.; Fernando, H. J. S.; Hamlet, Alan F.; Hellmann, J. J.; Chen, F. (2016): Green and cool roofs to mitigate urban heat island effects in the Chicago metropolitan area. Evaluation with a regional climate model. In Environ. Res. Lett. 11 (6), p. 64004–64004. DOI 10.1088/1748-9326/11/6/064004.

Urban albedo enhancement. "We have employed the urbanized version of the Weather Research and Forecasting (uWRF) model at high (1 km) resolution with physically-based rooftop parameterization schemes (conventional, green and cool), a first-time application to the Chicago metropolitan area. We simulated a hot summer period (16–18 August 2013) and assessed (i) UHI reductions for different urban landuse with green/cool roofs, (ii) the interaction of lake breeze and UHI, and (iii) diurnal boundary layer dynamics."

Nexus Media: Four Cool Ways to Clear the Air

"Scientists say we need drastically to cut carbon pollution. Not only that, we must look for ways to remove carbon from the atmosphere. Right now, trees are the best tool for the job. Artificial approaches to carbon capture remain too expensive to be practical on a large scale, but several methods show promise. Here are four."

IASS: First Climate Engineering Conference (CEC17) Steering Committee Meeting

"Following the success of the first international climate engineering conference in 2014 (CEC14), the IASS will host a second climate engineering conference in 2017 (CEC17). The conference will be held in late summer/early fall 2017 in Berlin and will serve three purposes: As an advanced review for the current state of climate engineering research, as a forum for developing synergies between academic, policy, and civic stakeholders, and as an exposition of the evolution, diversity, and relevance of this issue at an important stage in the development of options to mitigate climate change."

Daily Post: Oppenheimer Lecture: National Academy Of Sciences President Examines Question Of Climate Intervention

"The subject of McNutt’s lecture on “Climate Intervention: A Last Resort? is based on two parallel studies she chaired for the NAS Committee on Geoengineering Climate that were published simultaneously earlier this year. An interesting change in terminology can be detected, from “geoengineering” to “intervention.” Indeed, the committee was tasked with conducting “a technical evaluation of a limited number of proposed geoengineering techniques, including examples of both solar radiation management and carbon dioxide removal techniques.”"

Feng, Ellias Y.; et al. (2016): Could artificial ocean alkalinization protect tropical coral ecosystems from ocean acidification?

Feng, Ellias Y.; Keller, David P.; Koeve, Wolfgang; Oschlies, Andreas (2016): Could artificial ocean alkalinization protect tropical coral ecosystems from ocean acidification? In Environ. Res. Lett. 11 (7), p. 74008–74008. DOI 10.1088/1748-9326/11/7/074008.

"Artificial ocean alkalinization (AOA) is investigated as a method to mitigate local ocean acidification and protect tropical coral ecosystems during a 21st century high CO2 emission scenario. Employing an Earth system model of intermediate complexity, our implementation of AOA in the Great Barrier Reef, Caribbean Sea and South China Sea regions, shows that alkalinization has the potential to counteract expected 21st century local acidification in regard to both oceanic surface aragonite saturation Ω and surface pCO2."
