"This report discusses the near-term risks of climate change; possible techniques that can be used to directly reduce warming in the climate; possible risks, benefits, and costs of these techniques; on overview of governance cosiderations and mechanisms; the nature of research for these techniques; the current state of play; and recommendations for policymakers for exploring these approaches to expand options for ensuring safety."

"Direct air capture (DAC) is a technology for collecting and concentrating carbon dioxide from ambient air. If driven with renewable power, DAC is potentially a negative CO₂ emissions technology that can compensate emissions from non-point sources such as aviation, shipping and land-use change. This study presents the results of 10 days capture campaign done between May and July 2018 plus a process control improvement test."

"Stabilizing Earth's climate and limiting temperature increase to well below 2°C per the Paris Agreement requires a dramatic uptick in the rate of progress on reducing greenhouse gas (GHG) emissions. [...] Some of us have contributed to among the most optimistic assessments of the potential of NCS (1), whereas others have been more pessimistic (2, 3). But one thing on which we agree, and which technical literature generally acknowledges, is that the benefits of NCS do not decrease the imperative for mitigation from the energy and industrial sectors (2, 4, 5)."

"These shortcomings are partially the result of avoidable ‘blind spots’ relating to time lags inherent in the implementation of land-based mitigation strategies. Key blind spots include inconsistencies between different land-system policies, spatial and temporal lags in land-system change, and detrimental consequences of some mitigation options. We suggest that improved recognition of these processes is necessary to identify achievable mitigation actions, avoiding excessively optimistic assumptions and consequent policy failures."
