Emmerling, Johannes; et al. (2016): Climate Engineering under Deep Uncertainty and Heterogeneity

Emmerling, Johannes; Manoussi, Vassiliki; Xepapadeas, Anastasios (2016): Climate Engineering under Deep Uncertainty and Heterogeneity. Fondazione Eni Enrico Mattei (FEEM) (Nota di Lavoro, 52.2016).

„We study the role of the SRM implementation and its strategic dimension in a model with two heterogeneous countries with the notable feature of model misspecification on the impacts from SRM. We find that deep uncertainty leads to a reduction in SRM deployment both under cooperation and strategic behavior, which is a more relevant issue if countries act strategically.“

Rolling Stone: Can New York Be Saved in the Era of Global Warming?

„But the truth is, barring deployment of a radical geoengineering scheme that quickly cools the planet, we have already heated up the Earth’s atmosphere enough to guarantee that the seas are going to rise – and they are going to keep rising for a long time. Recent studies have shown that even if we stabilize the greenhouse-gas emissions at today’s levels, the oceans will still rise by as much as 70 feet in the coming centuries and stay that high for thousands of years. In that scenario, New York will become an archipelago on the coast, with the high ground of Upper Manhattan and parts of Brooklyn and Staten Island just above the waterline.“

Center for Carbon Removal: Science Friday – Carbon Negative Materials

„Carbon-negative materials are types of materials that result in the net sequestration of CO2 over their lifecycle. For these materials to actually be net-negative, the CO2 used to create these materials must be sourced from atmospheric or biogenic CO2. These materials can shift the narrative on traditionally high-polluting industries,[nbsp]turning CO2 from an invisible, pesky pollutant into a profitable, tangible resource to be mined from the sky!“

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.“
