为了防止危险的气候变化水平,《巴黎协定当事方》致力于将全球平均温度升高到远低于2°C,同时努力将温暖限制在工业前水平高1.5°C时。实现这些目标取决于人为温室气体排放的近期平稳性,然后快速减少排放。However, the growing delays in reducing emissions, coupled with the need for a net- negative emissions balance to reach net-zero emissions in the second half of the century, make this goal unachievable without the deployment of substantial amounts of Carbon Dioxide Removal (CDR), as affirmed by the Intergovernmental Panel on Climate Change (IPCC) in its Special Report on global warming of 1.5°C1 and它最近的第六次评估报告2。只有使用CDR,我们才能进一步解决越来越可能的过冲场景,在这种情况下,温度在再次降低之前暂时超过了巴黎目标。
