Want to limit carbon and curb wildfire? Create a market for small trees

University of California – Berkeley – ScienceDaily, 13 December 2021

Thinning treatments reduce the risk of wildfire and provide ecological benefits for California’s forests, but they also generate wood residues that are often burnt or left to decay, releasing carbon dioxide into the atmosphere. A new analysis shows how incentivizing industries that convert wood residues into useful products, including biofuels and construction-quality engineered lumber, could fund forest thinning treatments while preventing the release of carbon.

German conference: The oceans and seas under increasing pressure – An outlook on international ocean governance in 2022

Wed, December 15, 2021; 10:30 AM – 5:15 PM (in German only) via Zoom

For short notice: The year 2022 will represent a multitude of key decisions and directions for marine protection and international ocean policy. The conference already taken place focus on two aspects. On the one hand, it will emphasise the effects of climate change on the world’s oceans and the corresponding design of climate policy. Second, it will address the overarching relationship between environment and development in blue economy strategies. Thus, fundamental aspects of ocean policy will be discussed that play an important role in all of the international processes. Registration by e-mail was requested at: contact@fair-oceans.info

Opinion – Geoengineering: We should not play dice with the planet

by Kim Cobb and Michael E. Mann at „The Hill“

„To be clear, the world should continue to invest in research and development of science and technology that might hasten societal decarbonization and climate stabilization, and eventually the return to a cooler climate. But those technologies must be measured, in both efficacy and safety, against the least risky and most surefire path to a net-zero world: the path from a fossil fuel-driven to a clean energy-driven society.“

Launch of ambitious R&D program focused on ocean alkalinity enhancement

Thu, December 16, 2021 7:30 PM – 10:30 PM PST at AGU21

A philanthropic consortium, led by Additional Ventures, is launching an ambitious R&D program to rapidly accelerate our understanding of ocean alkalinity enhancement and build solutions for the scalable, cost-efficient, and environmentally safe deployment of OAE. Please join us as we publish two large Requests for Proposals. The launch event will be held in person in New Orleans, LA scheduled during the AGU Fall Meeting 2021.

Fahr et al. (2021): Assessing the physical potential capacity of direct air capture with integrated supply of low-carbon energy sources

Steffen Fahr, Julian Powell, Alice Favero, Anthony J. Giarrusso, Ryan P. Lively, Matthew J. Realff IN: Greenhouse. Gas. Sci. Technology 0:1–18 (2021); DOI: 10.1002/ghg.2136

This study explores the potential of low-carbon energy sources to supply power and heat to the DAC process in a dedicated, self-sufficient system tailored for each energy source. Solar, geothermal, woody biomass, wind, and nuclear energy sources are assessed for their global energy supply potential and possible land use requirements.

How to secure carbon removal for your net zero pledge?

by PuroEarth

A webinar with CEO, Antti Vihavainen, he talks how Pre-CORC takeoff agreements work and meet the supplier of negative emissions: Carbo Culture. Carbo Culture is a Puro.earth current and Pre-CORC supplier of biochar-based technology to permanently keep carbon from the atmosphere. Tim Preisenhammer, Head of Commercialization, talks about the firm’s plans for a new facility, long term vision and how your company can contribute to reaching these ambitious goals.

Nature – Wang et al. (2021): Global cooling induced by biophysical effects of bioenergy crop cultivation

Jingmeng Wang, Wei Li, Philippe Ciais, Laurent Z. X. Li, Jinfeng Chang, Daniel Goll,Thomas Gasser, Xiaomeng Huang, Narayanappa Devaraju, Olivier Boucher IN: Nature Communications 12, 7255 (2021). https://doi.org/10.1038/s41467-021-27520-0

Here, using a coupled atmosphere-land model with an explicit representation of lignocellulosic bioenergy crops, it is presented that after 50 years of large-scale bioenergy crop cultivation following plausible scenarios, global air temperature decreases by 0.03~0.08 °C, with strong regional contrasts and interannual variability. The study calls for new metrics to take the biophysical effects into account when assessing the climate mitigation capacity of BECCS.
