"In this session we want to bring together experts on ONETs to assess and discuss their feasibilities, costs, and side-effects. We explicitly also welcome experts working on interactions between, as well as mutual benefits of, ocean- and land-based NETs."

"A comprehensive new analysis involving researchers from UEA warns that the target of limiting global warming to 1.5ºC could soon become too economically expensive to justify, despite the benefits it could provide."

"Here, we investigate to what extent a proponent of the 2 °C-temperature target would apply SGE in conjunction with mitigation in view of regional disparities in temperature and precipitation. We apply cost-risk analysis (CRA), which is a decision analytic framework that trades-off expected welfare-loss from climate policy costs and climate risks from transgressing a climate target. Here, in ‘Giorgi’-regional-scale analyses, we evaluate the optimal mix of SGE and mitigation under probabilistic information about climate sensitivity and generalize CRA in order to include regional temperature and precipitation risks."

"Faced with roadblocks to reducing greenhouse gas emissions via globally meaningful regulations or carbon pricing schemes, some scientists say it's time to consider even more drastic human intervention."
