"Scientists have developed an accelerated way to produce magnesite, a mineral which can capture the greenhouse gas carbon dioxide from the atmosphere, at room temperature. Removing carbon dioxide from the atmosphere would slow global warming. This work takes a different approach to existing processes, and may make it economically viable, but it is at an early stage and is not yet an industrial process."

"Peter Fiekowsky joined Earth911’s Sustainability In Your Ear podcast recently to explain direct air capture, a technology that extracts carbon dioxide from the air. Peter also spoke with Earth911 in June about ocean iron fertilization, another approach to sequestering carbon on the ocean floor."

Harper, A. B.; Powell, T.; Cox, P. M.; House, J.; Huntingford, C.; Lenton, T. M. et al. (2018): Land-use emissions play a critical role in land-based mitigation for Paris climate targets. In: Nat Comms 9 (1), S. 405. DOI: 10.1038/s41467-018-05340-z.

"Here we show that additional land-use change to meet a 1.5 °C climate change target could result in net losses of carbon from the land. The effectiveness of BECCS strongly depends on several assumptions related to the choice of biomass, the fate of initial above ground biomass, and the fossil-fuel emissions offset in the energy system. Depending on these factors, carbon removed from the atmosphere through BECCS could easily be offset by losses due to land-use change. If BECCS involves replacing high-carbon content ecosystems with crops, then forest-based mitigation could be more eficient for atmospheric CO2 removal than BECCS."
