The Guardian: Regreening the planet could cut as much carbon as halting oil use – report

"Natural solutions such as tree planting, protecting peatlands and better land management could account for 37% of all cuts needed by 2030, says study"

Stop GE Trees: Report: Large-scale Biosequestration Causing Negative Social and Environmental Impacts

"At the start of a major Climate Engineering Conference in Berlin, the Global Forest Coalition has launched a Working Paper that highlights the risks of different proposals for large-scale Carbon Dioxide Removal. The report finds that while the most prominent CDR approach, Bioenergy and Carbon Capture and Storage (BECCS) technology is still in a state of “infancy” and is unlikely to be rolled out on a global scale, biosequestration in the form of afforestation through monoculture tree plantations is already rapidly expanding and causing significant negative social and environmental impacts."

Fern: Energy Union Governance Regulation: Europe’s opportunity to set a negative emissions target

"This must include targets to generate negative emissions by restoring Europe’s forests, the cheapest and most readily available tool we have. Discussions in the European Parliament’s Environment and Energy Committees – which are leading the drafting of the Parliament’s position on the Regulation – have been promising. Parties from across the political spectrum including the centre-right European Peoples’ Party (EPP), the centrist Alliance of Liberals and Democrats for Europe (ALDE), and the centre-left Socialists and Democrats party (S&D) have put forward language around a long-term target to increase the EU’s forests. "

Quartz: Tropical forests used to absorb carbon. Now they emit as much as all US transit

"Some countries are now investing heavily in the future of geoengineering—large-scale technological solutions to suck carbon out of the atmosphere. Baccini thinks we ought to be planting trees. “We are not there yet” with even the most promising geoengineering approaches. “For the next 50 years, it would be more effective to just do it using a more natural system,” he says. “The most effective way to do it fast, and in a cheap way, is doing it with a forest.”"

Mother Jones: China’s Crazy Plan to Keep Sand From Swallowing the World

 

"The view from the top of this windblown hill in Duolun County, in China’s Inner Mongolia region, could be described as either profoundly inspiring or deeply strange. For miles around, the earth is dun-colored and dry, stubbled with yellow grass. But the hillsides directly across from me are emblazoned with vast swaths of trees planted in geometric shapes: a square, a circle, overlapping triangles. The flatland below is striped with bands of identical young pines, standing in rigid formation like soldiers on parade."

Boysen, Lena R.; et al. (2017): Trade-offs for food production, nature conservation and climate limit the terrestrial carbon dioxide removal potential

Boysen, Lena R.; Lucht, Wolfgang; Gerten, Dieter (2017): Trade-offs for food production, nature conservation and climate limit the terrestrial carbon dioxide removal potential. In Glob Chang Biol. DOI: 10.1111/gcb.13745.

"We integrate these factors in one spatially explicit biogeochemical simulation framework to explore the tCDR opportunity space on land available after these constraints are taken into account, starting either in 2020 or 2050, and lasting until 2100. We find that assumed future needs for nature protection and food production strongly limit tCDR potentials. BPs on abandoned crop and pasture areas (~1300 Mha in scenarios of either 8.0 billion people and yield gap reductions of 25% until 2020 or 9.5 billion people and yield gap reductions of 50% until 2050) could, theoretically, sequester ~100 GtC in land carbon stocks and biomass harvest by 2100."

GDAE (2017): Hope Below Our Feet. Soil as a Climate Solution

GDAE (2017): Hope Below Our Feet. Soil as a Climate Solution. With assistance of Anne-Marie Codur, Seth Itzkan, William Moomaw, Karl Thidemann, Jonathan Harris. Global Development and Environment Institute (Climate Policy Briefing, 4).

"Soils hold about three times more carbon than the atmosphere, and an increase in soil carbon content worldwide could close the “emissions gap” between carbon dioxide reductions pledged at the Paris Agreement of 2015 and those deemed necessary to limit warming to 2oC or less by 2100. To meet this challenge, several international efforts to build soil carbon have been launched, with similar measures underway in the United States."

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."

Science: Is wood a green source of energy? Scientists are divided

"The bottom line for climate can shift depending on how far into the future researchers peer. The EPA panel on which Abt and Khanna sit has endorsed a long view. In its latest draft, the group recommends doing carbon accounting over a 100-year timeframe, based on research suggesting that it takes that long for the planet to feel the full impact of cumulative greenhouse gas emissions. Such long tallies give new forests plenty of time to mature and recapture carbon, making wood appear closer to carbon neutral."
