"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."

"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."

"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 dioxide 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."

"This book is devoted to CO₂ capture and utilization (CCU) from a green, biotechnological and economic perspective, and presents the potential of, and the bottlenecks and breakthroughs in converting a stable molecule such as CO₂ into specialty chemicals and materials or energy-rich compounds."
