Video: PBS: Engineering Earth’s Climate?

"Scientists are worried that soon, simply reducing carbon emissions won’t be enough to even slow global warming.  A U.N. panel has said the world will likely need to “geo-engineer” the climate. That’s an idea that dates to the Cold War, when a different kind of global challenge gave rise to fears of a “nuclear winter.”"

Roe, Stephanie; et al.: Contribution of the land sector to a 1.5 °C world

Roe, Stephanie; Streck, Charlotte; Obersteiner, Michael; Frank, Stefan; Griscom, Bronson; Drouet, Laurent et al.: Contribution of the land sector to a 1.5 °C world. In Nat. Clim. Chang., pp. 1–12. DOI: 10.1038/s41558-019-0591-9.

"The Paris Agreement introduced an ambitious goal of limiting warming to 1.5 °C above pre-industrial levels. Here we combine a review of modelled pathways and literature on mitigation strategies, and develop a land-sector roadmap of priority measures and regions that can help to achieve the 1.5 °C temperature goal. "

Ecosystem Marketplace: Will Small Forest Owners Finally Be Able To Tap Carbon Markets?

"Carbon finance can, in theory, help small landowners around the world improve the way they manage their forests by providing that little bit of extra income that can make sustainable forest management pay. In practice, high transaction costs and low carbon prices have limited uptake – but that’s changing, thanks to new technologies and finance strategies."

The Sunday Times: Letters to the Editor: Technology can’t solve climate crisis

"Bryan Appleyard’s argument that technology can solve the climate crisis is unconvincing (“Can we fix it?”, News Review, last week). Indeed, some of the more Heath Robinson geoengineering remedies he describes may have unintended consequences as damaging as climate change itself."

Lefebvre, D. A., et al. (2019). Assessing the potential of soil carbonation and enhanced weathering through Life Cycle Assessment: A case study for Sao Paulo State, Brazil

Lefebvre, D. A., Goglio, P. C. D., Williams, A., Manning, D., Azevedo, A., Bergmann, M., Meersmans, J., Smith, P. (2019). Assessing the potential of soil carbonation and enhanced weathering through Life Cycle Assessment: A case study for Sao Paulo State, Brazil. Journal of Cleaner Production, 233, 468–481. doi: 10.1016/j.jclepro.2019.06.099.

"In this paper, we investigate the established mining industry that extracts basaltic rocks for construction from the Paraná Basin, Sao Paulo State, Brazil. Through a Life Cycle Assessment, we determine the balance of carbon dioxide emissions involved in the use of this material, the relative contribution of soil carbonation and enhanced weathering, and the potential carbon dioxide removal of Sao Paulo agricultural land through enhanced weathering of basalt rock."

Goglio, P., et al. (2019). Advances and challenges of life cycle assessment (LCA) of greenhouse gas removal technologies to fight climate changes

Goglio, P., Williams, A., Balta-Ozkan, N., Harris, N., Williamson, P., Huisingh, D., Zhang Z., Tavoni, M. (2019). Advances and challenges of life cycle assessment (LCA) of greenhouse gas removal technologies to fight climate changes. Journal of Cleaner Production, 118896. doi: 10.1016/j.jclepro.2019.118896.

"In this article, challenges for LCA are reviewed and discussed together with some alternative approaches for assessment of GGRTs. In particular, GGRTs pose challenges with regards to the functional unit, the system boundary of the LCA assessment, and the timing of emissions."

Grainger, A., et al. (2019). Comment on “The global tree restoration potential.”

Grainger, A., Iverson, L. R., Marland, G. H., & Prasad, A. (2019). Comment on “The global tree restoration potential.” Science, 366(6463). doi: 10.1126/science.aay8334

"Bastin et al. (Reports, 5 July 2019, p. 76) neglect considerable research into forest-based climate change mitigation during the 1980s and 1990s. This research supports some of their findings on the area of land technically suitable for expanding tree cover, and can be used to extend their analysis to include the area of actually available land and operational feasibility."
