Conservation news: Fighting climate change with bioenergy may do ‘more harm than good’

"A major source of energy oft-extolled as renewable is biomass from trees, which are usually harvested from managed forests either established on land that has already been deforested or planted where forests didn’t naturally grow. But a new study finds land-use like managing forests for biomass production may come at a much higher carbon cost than previously thought."

Erb, Karl-Heinz; et al. (2017): Unexpectedly large impact of forest management and grazing on global vegetation biomass

Erb, Karl-Heinz; Kastner, Thomas; Plutzar, Christoph; Bais, Anna Liza S.; Carvalhais, Nuno; Fetzel, Tamara et al. (2017): Unexpectedly large impact of forest management and grazing on global vegetation biomass. In Nature. DOI: 10.1038/nature25138.

"Therefore, avoiding deforestation is necessary but not sufficient for mitigation of climate change. Our results imply that trade-offs exist between conserving carbon stocks on managed land and raising the contribution of biomass to raw material and energy supply for the mitigation of climate change. Efforts to raise biomass stocks are currently verifiable only in temperate forests, where their potential is limited. By contrast, large uncertainties hinder verification in the tropical forest, where the largest potential is located, pointing to challenges for the upcoming stocktaking exercises under the Paris agreement."

Mongabay: Consensus grows: climate-smart agriculture key to Paris Agreement goals

"Attendees at the annual Global Landscape Forum conference in Bonn, Germany, this week sought approaches for implementing “climate-smart” agricultural practices to help keep global temperature from rising more than 2 degrees Celsius (3.6 degrees Fahrenheit) by 2100."

Emmerling, Johannes; Tavoni, Massimo (2017): Quantifying Non-cooperative Climate Engineering

Emmerling, Johannes; Tavoni, Massimo (2017): Quantifying Non-cooperative Climate Engineering. Fondazione Eni Enrico Mattei (FEEM) (Working Paper, 058).

"This paper provides the first quantitative evaluation of the risks of free driving. Our results indicate that in a strategic setting there is significant over-provision (by almost an order of magnitude) of climate engineering above what is socially optimal, resulting in a sub-optimal global climate. Regions with high climate change impacts, most notably India and developing Asia, deploy climate engineering at the expenses of other regions."

Fast Company: Can We Suck Enough CO2 From The Air To Save The Climate?

"As we try to slow our carbon emissions, we also need to get carbon out of the air. A new industry is springing up to meet the challenge, but can it scale fast enough?"

IIED: Geoengineering and development – what price on equity and justice in the coming climate culture wars?

"Climate geoengineering is a divisive topic. What could be good – the promise of ways to either cool the planet through enhancing the reflection of sunlight, or to remove CO2 from the atmosphere thereby reducing global warming – could also be terrible. Particularly if banking on hypothetical solutions from unproven technology reduces the urgency of efforts to stop putting greenhouse gases into the atmosphere."
