„Here, we review and summarize the available literature on the effects of biochar on soil properties and GHG emissions in forest soils.“
„The word for this, if we are being honest, is ‘geo-engineering.’ It’s a very gentle, low-tech kind of geo-engineering, with relatively little chance of major negative side-effects if we get it wrong. We are definitely still on the learner slopes. The interventions in natural systems will get much bigger, and the penalties for mistakes much more costly, as time goes on.„

„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.“

„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.“
„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.“

„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.“
