All the above presupposes that emissions cannot go below zero in the future, thereby drawing carbon dioxide out of the atmosphere and eventually correcting any overshoot of the carbon budget and its associated temperature goal. But negative emissions are a possibility, through the implementation of ...
those scenarios mandate not just heroic emission cuts but also 'negative emissions'—techniques that actively remove carbon dioxide from the atmosphere, thus paying back some
Last year, a report1 produced by the Coalition for Negative Emissions argued that taken together, a portfolio of leading CDR solutions such as Natural Climate Solutions (NCS), bioenergy with carbon capture and storage (BECCS) ...

The other option is to say that 2oC is a ‘benchmark’ (only slightly better than an ‘aspirational target?’) and put our faith in climate inertia allowing humanity to overshoot on emissions and then increase the amount of sequestration (negative emissions) to pull back from the brink of ...

Methods may be required for net capture and storage, physical leakage, fugitive emissions, and negative emissions associated with biomass applications of CCS Cross-border issues associated with CCS accounting (e.g., capture in one country and storage in another country with different committments) al...
Ridley said most experts believed that warming of less than 2C from pre-industrial levels would result in no net economic and ecological damage. “Therefore, the new report is effectively saying (based on the middle of the range of the IPCC’s emissions scenarios) that there is abetter than...
IPCC第五次评估报告对全球气候变化认知的科学要点一、概述IPCC(IntergovernmentalPanelonClimateChange,联合国气候变化专门委员会)是由世界气象组织(WMO)和联合国环境规划署(UNEP)于1988年联合建立的,旨在为各国政府提供关于气候变化的科学、技术和社会经济方面的客观信息,以帮助制定应对气候变化的政策和措施。IPCC的工作组...
