Abstract. Intergovernmental Panel on Climate Change (IPCC) assessments are the trusted source of scientific evidence for climate negotiations taking place under the United Nations Framework Convention on Climate Change (UNFCCC), including the first global stocktake under the Paris Agreement that will conclude at COP28 in December 2023. Evidence-based decision making needs to be informed by up-to-date and timely information on key indicators of the state of the climate system and of the human influence on the global climate system. However, successive IPCC reports are published at intervals of 5–10 years, creating potential for an information gap between report cycles. We base this update on the assessment methods used in the IPCC Sixth Assessment Report (AR6) Working Group One (WGI) report, updating the monitoring datasets and to produce updated estimates for key climate indicators including emissions, greenhouse gas concentrations, radiative forcing, surface temperature changes, the Earth’s energy imbalance, warming attributed to human activities, the remaining carbon budget and estimates of global temperature extremes. The purpose of this effort, grounded in an open data, open science approach, is to make annually updated reliable global climate indicators available in the public domain (https://doi.org/10.5281/zenodo.7883758, Smith et al., 2023). As they are traceable and consistent with IPCC report methods, they can be trusted by all parties involved in UNFCCC negotiations and help convey wider understanding of the latest knowledge of the climate system and its direction of travel. The indicators show that human induced warming reached 1.14 [0.9 to 1.4] °C over the 2013–2022 period and 1.26 [1.0 to 1.6] °C in 2022. Human induced warming is increasing at an unprecedented rate of over 0.2 °C per decade. This high rate of warming is caused by a combination of greenhouse gas emissions being at an all-time high of 57 ± 5.6 GtCO₂e over the last decade, as well as reductions in the strength of aerosol cooling. Despite this, there are signs that emission levels are starting to stabilise, and we can hope that a continued series of these annual updates might track a real-world change of direction for the climate over this critical decade.

2022年全球气候变化指标：每年更新气候系统状况和人类影响的大规模指标

摘要。政府间气候变化专门委员会 (IPCC) 的评估是根据《联合国气候变化框架公约》(UNFCCC) 进行的气候谈判的可靠科学证据来源，包括将于 12 月在 COP28 上结束的《巴黎协定》下的首次全球盘点2023. 循证决策需要以有关气候系统状态和人类对全球气候系统影响的关键指标的最新和及时信息为依据。然而，连续的 IPCC 报告每隔 5-10 年发布一次，这可能会在报告周期之间造成信息差距。我们的更新基于 IPCC 第六次评估报告 (AR6) 第一工作组 (WGI) 报告中使用的评估方法，更新监测数据集并生成关键气候指标的最新估计值，包括排放量、温室气体浓度、辐射强迫、地表温度变化、地球能量失衡、人类活动造成的变暖、剩余碳预算和全球极端温度估计值。这项基于开放数据、开放科学方法的努力的目的是在公共领域提供每年更新的可靠全球气候指标（https://doi.org/10.5281/zenodo.7883758，Smith 等人， 2023 年）。由于它们具有可追溯性并与 IPCC 报告方法一致，因此它们可以得到参与 UNFCCC 谈判的所有各方的信任，并有助于传达对气候系统及其行进方向的最新知识的更广泛理解。指标显示，人为导致的变暖在 2013-2022 年期间达到 1.14 [0.9 至 1.4] °C，2022 年达到 1.26 [1.0 至 1.6] °C。人为导致的变暖正以每十年超过 0.2 °C 的前所未有的速度增加. 这种高变暖率是由温室气体排放量达到历史最高水平 57 ± 5.6 GtCO 共同造成的₂ e 在过去十年中，以及气溶胶冷却强度的降低。尽管如此，有迹象表明排放水平开始趋于稳定，我们可以希望这些年度更新的连续系列可以追踪到这个关键十年的真实世界气候变化方向。
