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."

AP: Oman's mountains may hold clues for reversing climate change

"Deep in the jagged red mountains of Oman, geologists are searching for an efficient and cheap way to remove carbon dioxide from the air and oceans - and perhaps begin to reverse climate change.´They are coring samples from one of the world's only exposed sections of the Earth's mantle to uncover how a spontaneous natural process millions of years ago transformed carbon dioxide into limestone and marble."

Energy Collective: Carbon Capture on Biofuels: A Path to Net Negative Emissions

On BECCS. "On April 7, Archer Daniels Midland, the food processing and biofuels company, began permanently storing carbon dioxide 7000 feet underground, adjacent to its Decatur, Illinois corn ethanol plant.  At full capacity, the Illinois Industrial carbon capture and storage facility will prevent one million metric tonnes per year of carbon dioxide (CO2) from entering the atmosphere.  That is equivalent to taking more than 200,000 cars off the road, or eliminating emissions from more than 100,000 typical American homes."
