Shared Socioeconomic Pathways (SSPs) are climate change scenarios of projected socioeconomic global changes up to 2100 as defined in the IPCC Sixth Assessment Report on climate change in 2021. [2] They are used to derive greenhouse gas emissions scenarios with different climate policies.

RCPs是一系列综合的浓缩和排放情景，用作21世纪人类活动影响下气候变化预测模型的输入参数 (Moss et al., 2010)，以描述未来人口、社会经济、科学技术、能源消耗和土地利用等方面发生变化时，温室气体、反应性气体、气溶胶的排放量，以及大气成分的浓度（表1）。 表中 辐射强迫 （Radiative forcing）表示大气成分（如， CO_2 ）发生变化时，对流层中辐射的收支平衡变化，不同的辐射强迫路径是不同社会经济和技术发展情景的体现。 RCPs包括一个高排放情 …

Understand how SSPs differ from Representative Concentration Pathways (RCPs) and learn about key considerations when using SSPs in climate risk assessments. Learn about the latest set of emissions scenarios based on Shared Socioeconomic Pathways (SSPs).

The climate forcing in the baseline depends on the SSP, and only reaches RCP8.5 levels in SSP5. Stringent mitigation levels (RCP2.6) could not be accessed by a set of IAMs in SSP3.

2024年2月28日 · SSP是Shared Socioeconomic Pathway（ 共享社会经济路径 ）的缩写，对于未来变化情景综合考虑了SSP-RCP。 新的情景CMIP6弥补了SSPs与RCPs之间联系不够紧密的不足。共包含8组未来情景试验，根据优先级分为两个小组：Tier-1和Tier-2。

2018年4月19日 · Over the past few years, an international team of climate scientists, economists and energy systems modellers have built a range of new “pathways” that examine how global society, demographics and economics might change over the next century. They are collectively known as the “Shared Socioeconomic Pathways” (SSPs).

What are the Shared Socioeconomic Pathways (SSPs)? The Shared Socioeconomic Pathways are a set of scenarios which are central to the work of the UN climate reports produced by the Intergovernmental Panel on Climate Change (IPCC). Why are these scenarios so important for the IPCC report?

2020年8月13日 · The SSP concentration time series derived in this study provide a harmonized set of input assumptions for long-term climate science analysis; they also provide an indication of the wide set of futures that societal developments and policy implementations can lead to – ranging from multiple degrees of future warming on the one side to ...

2017年1月1日 · Our SSP scenarios quantify energy and land-use developments and associated uncertainties for greenhouse gas and air pollutant emissions. We conduct an SSP mitigation analysis, and estimate mitigation costs. We find that very low climate targets might be out of reach in SSPs featuring high challenges.

2019年5月15日 · Global climate change studies rely on numerous assumptions and factors related to policy options and societal developments. Shared Socioeconomic Pathways (SSPs) were developed over the last years as a joint community effort (by an international team of climate scientists, economists and energy
