„New technology is required to make meaningful progress on climate change. This column will focus on one of those options: decreasing the CO2 already in our atmosphere.“
„In 2015 and 2016, a bill was introduced in the Rhode Island House of Representatives to regulate climate geoengineering — an attempt that caught many by surprise, as legislating a technology with global impacts on the state level is a novel approach. In this forum,[nbsp]Wil Burns, Co-Executive Director of the Forum for Climate Engineering Assessment, who helped re-draft the bill in 2016, science and technology policy experts, and political scientists discuss this move: its drawbacks, merits, and lessons learned. – Holly Jean Buck“
The news review of calendar week 35 in 2016 is now available here.
„With climate change now being a certainty, governments around the world are investing time and money into solutions for the world’s largest problem. But some climate scientists have warned we’re too far gone to reverse the consequences, leaving us with only one option: climate hacking.“
„No one believes solar geoengineering is a climate change cure-all. And, like almost all innovations, it has known and unknown side effects. For one thing, it doesn’t deal with ocean acidification. For another, we don’t yet know enough about its effects on atmospheric ozone, for example, or on rainfall, or how it might help one region and hurt another.„
„The big concern for me, though, being from a small island which suffers greatly from the negative impact of climate change, is that it could also provide an incentive for countries not to reduce their greenhouse emissions. Instead, they would rely on this technology, which would be defeating the whole purpose to combating climate change. It could give people a false sense of hope,“ Mahlung told The Gleaner.“
„Welcome to Science Special! The weekly post where we bring you the best research and reports on different carbon removal technologies. This week’s topic is wetland restoration: The simple process of photosynthesis on a grand scale can benefit the world’s push to reduce and remove carbon. Wetlands can be particularly helpful in this quest since their saturated soils prevent the decay of biomass, effectively storing carbon in large quantities.“
„Civil society has been questioning and opposing geoengineering for almost 20 years. What began as[nbsp]a reaction to technocratic hubris rapidly evolved into worldwide protests against[nbsp]attempts to initiate ocean fertilization and a consensus of civil society and Global South opposition at the[nbsp]2010[nbsp]People’s Summit in Cochabamba.“

Impacts on food prices under consideration of albedo effects. In Environ. Res. Lett. 11 (8), p. 85001–85001. DOI 10.1088/1748-9326/11/8/085001
„We assessed the food price response of afforestation, and considered the albedo effect with scenarios in which afforestation was restricted to certain latitudinal zones. In our study, afforestation was incentivized by a globally uniform reward for carbon uptake in the terrestrial biosphere. This resulted in large-scale afforestation (2580 Mha globally) and substantial carbon sequestration (860 GtCO2) up to the end of the century.“
