Harvard Crimson: Harvard Researchers Launch Solar Geoengineering Moonshot

"Launched this weekend, Harvard’s Solar Geoengineering Research Program will investigate the safety of geoengineering as well as its environmental and political implications. Scientists specifically look into a technique of injecting specific particles into Earth’s upper atmosphere to create a barrier that reflects more sunlight away from the atmosphere."

MIT Technology Review: The Growing Case for Geoengineering

"As climate change accelerates, a handful of scientists are eager to move ahead with experiments testing ways to counteract warming artificially. Their reasoning: we just might get desperate enough to use this technology one day."

Desmog: Biochar Series

"In this series, DeSmog digs into the promise and peril of biochar as a solution to climate change. Authored by Steve Horn, this investigative report is the result of a years-long probe into biochar, geoengineering, and whether it can put a dent in climate change. Learn about the science — and lack thereof — supporting biochar's carbon sequestration potential, the major players and their connections to Big Oil, and the rush to deploy large-scale biochar projects as part of questionable carbon offsets programs. Read the whole series below."

Desmog: Introducing Biochar: Climate Change Solution or Greenwash Nightmare?

"Momentum on biochar as a climate salvation, for now, has reached a relative standstill. But the industry has already written the playbook for pushing its product, and should that momentum turn around in the months and years ahead, the biggest question will be: Can research confirm biochar's potential as a climate change solution, or is it just another form of greenwashing?"

Daily Texan: Geoengineering proves poor solution to climate change

"As Donald Trump’s presidency continues, it has become clear that acting for the benefit of the environment and the future human population is not in his or the Republican Party’s plans. After the undoing of Obama’s climate change policy last month, which includes the Clean Power Plan, scientists are looking for solutions outside of reducing carbon emissions, such as geoengineering."

Center for Carbon Removal: 5 Gt of negative emissions by 2050?

"A group of European scientists recently published a paper titled, “A roadmap for rapid decarbonization” in the journal Science that attempts to change just that. The paper lays out what the authors dubbed the “Carbon Law,” which explains a simple heuristic for what we need to do meet our climate goals. The “Carbon Law” proposes that we will have to halve our CO2 emissions each decade starting in 2020 while also ramping up carbon removal rapidly starting in only a few decades time to achieve net zero emissions by 2050 (and reducing land sector emissions to zero) as described in the chart, below. And while the Paris Agreement targets will be challenging to meet, the “Carbon Law” analysis reveals important points about carbon removal -- and just how critical it will be for the Paris Agreement."

Bright, Ryan M.; et al. (2017): Local temperature response to land cover and management change driven by non-radiative processes

Bright, Ryan M.; Davin, Edouard; O’Halloran, Thomas; Pongratz, Julia; Zhao, Kaiguang; Cescatti, Alessandro (2017): Local temperature response to land cover and management change driven by non-radiative processes. In Nature Climate change 7 (4), pp. 296–302. DOI: 10.1038/nclimate3250.

"Here, we combine extensive records of remote sensing and in situ observation to show that non-radiative mechanisms dominate the local response in most regions for eight of nine common LCMC perturbations. We find that forest cover gains lead to an annual cooling in all regions south of the upper conterminous United States, northern Europe, and Siberia—reinforcing the attractiveness of re-/afforestation as a local mitigation and adaptation measure in these regions."
