Forum for Climate Enigneering Assessment: When essential research might be a bad thing. The carbon removal research dilemma. (Blogpost)

"The UK recently adopted a legislative 2050 target for ‘net-zero’ climate-changing emissions. Other countries are also moving towards similar goals. Such targets are hugely welcome in the face of growing climate change impacts. Yet delivering ‘net-zero’ depends not only on accelerated mitigation, but also critically on the development and deployment of carbon removal techniques. This creates something of a dilemma."

RealClimate: Can planting trees save our climate?

"n recent weeks, a new study by researchers at ETH Zurich has hit the headlines worldwide (Bastin et al. 2019). [...] Unfortunately, it’s also too good to be true. Because apples are compared to oranges and important feedbacks in the Earth system are forgotten. With a few basic facts about the CO2 increase in our atmosphere this is easy to understand. Mankind is currently blowing 11 billion tonnes of carbon (gigatonnes C, abbreviated GtC) into the air every year in the form of CO2 – and the trend is rising."

Phys.org: Exaggerating how much carbon dioxide can be absorbed by tree planting risks deterring crucial climate action

"Planting almost a billion hectares of trees worldwide is the "biggest and cheapest tool" for tackling climate change, according to a new study. The researchers claimed that reforestation could remove 205 gigatons of carbon dioxide (CO2) from the atmosphere—equivalent to about 20 years' worth of the world's current emissions. This has been criticized as an exaggeration. It could actually be dangerous."

Union of Concerned Scientists: Can Trees, Oceans and Giant Carbon Sucking Machines Save Us from Climate Catastrophe? (Blog)

"As we confront ever more obvious impacts of a warming world, we must immediately tackle the political and technical challenges of reducing the pollution causing climate change. And, just as actively, seek ways to remove, store and manage carbon to bring our climate back into balance."

Phys.org: Breaching a 'carbon threshold' could lead to mass extinction

"Daniel Rothman, professor of geophysics and co-director of the Lorenz Center in MIT's Department of Earth, Atmospheric and Planetary Sciences, has found that when the rate at which carbon enters the oceans pushes past a certain threshold—whether as the result of a sudden burst or a slow, steady influx—the Earth may respond with a runaway cascade of chemical feedbacks, leading to extreme ocean acidification that dramatically amplifies the effects of the original trigger."

Global Ground: Is it time for a radical new approach to fighting global warming? (Podcast)

"One may call it a crazy idea. Someone else may say its an expression of desperation about the lack of action on climate change. Despite the regretful tone, however, these comments are from researchers who advocate further study into whether climate engineering could be part of the answer to alleviate global warming."

Francaviglia, R.; et al. (2019): Assessing “4 per 1000” soil organic carbon storage rates under Mediterranean climate: a comprehensive data analysis

Francaviglia, R.; Di Bene, C.; Farina, R.; Salvati, L.; Vicente-Vicente, J. (2019): Assessing “4 per 1000” soil organic carbon storage rates under Mediterranean climate: a comprehensive data analysis. In: Mitig Adapt Strat Glob Change 24 (5), S. 795–818. DOI: 10.1007/s11027-018-9832-x.

"Soil Organic Carbon (SOC) is considered a proxy of soil health, contributing to food production, mitigation, and adaptation to climate change and other ecosystem services. Implementing Recommended Management Practices (RMPs) may increase SOC stocks, contributing to achieve the United Nations Framework Convention on Climate Change 21st Conference of the Parties agreements reached in Paris, France. In this framework, the “4 per 1000” initiative invites partners implementing practical actions to reach a SOC stock annual growth of 4‰."

Caves Rugenstein, J.; et al. (2019): Neogene cooling driven by land surface reactivity rather than increased weathering fluxes

Caves Rugenstein, J.; Ibarra, D.; Blanckenburg, F. von (2019): Neogene cooling driven by land surface reactivity rather than increased weathering fluxes. In: Nature 571 (7763), S. 99–102. DOI: 10.1038/s41586-019-1332-y.

"The long-term cooling, decline in the partial pressure of carbon dioxide, and the establishment of permanent polar ice sheets during the Neogene period have frequently been attributed to increased uplift and erosion of mountains and consequent increases in silicate weathering, which removes atmospheric carbon dioxide. However, geological records of erosion rates are potentially subject to averaging biases, and the magnitude of the increase in weathering fluxes—and even its existence—remain debated. "
