This study developed spatially complete global monthly ST anomaly datasets for 1850–2024 with a spatial resolution of 5° × 2.5°, termed the China global Artificial Intelligence Reconstructed Surface Temperature20CR/CMIP6 (C-AIRSTR/M) datasets, which are reconstructed independently using the 20CR-AI and CMIP6-AI schemes based on the merged C-LSAT2.1 and HadSST4.

We reassess the basis for determining the present level of long-term global warming. Unbiased estimates of both realised warming and anthropogenic warming are possible that approximate a 20-year retrospective mean. Our resulting estimates of 1.40 [1.23–1.58] °C (realised) and 1.34 [1.18–1.50] °C (anthropogenic) as at end of 2024 highlight the urgency of immediate, far-reaching and sustained climate mitigation actions if we are to meet the long term temperature goal of the Paris Agreement.

ERC firstly unified the evaluating, ranking, and clustering by a simple mathematic equation based on Euclidean Distance. It provides new system to solve the evaluating, ranking, and clustering tasks in SDGs. In fact, ERC system can be applied in any scientific domain.

This paper develops an observational integrated and homogenized global-terrestrial (except for Antarctica) SSRIH station. This is interpolated into a 5° × 5° SSRIH grid and reconstructed into a long-term (1955–2018) global land (except for Antarctica) 5° × 2.5° SSR anomaly dataset (SSRIH20CR) by an improved partial convolutional neural network deep-learning method. SSRIH20CR yields trends of −1.276 W m−2 per decade over the dimming period and 0.697 W m−2 per decade over the brightening period.

Short summary
The new China global Merged Surface Temperature CMST 2.0 is the updated version of CMST-Interim used in the IPCC's AR6. The updated dataset is described in this study, containing three versions: CMST2.0 – Nrec, CMST2.0 – Imax, and CMST2.0 – Imin. The reconstructed datasets significantly improve data coverage, especially in the high latitudes in the Northern Hemisphere, thus increasing the long-term trends at global, hemispheric, and regional scales since 1850.

This paper documents the various procedures necessary to construct a homogenized daily maximum and minimum temperature series starting in 1887 for Tianjin. The newly constructed temperature series provides a set of new baseline data for the field of extreme climate change at the century-long scale and a reference for construction of other long-term reliable daily time series in the region.

Short summary
This study introduces the update to the C-LSAT 2.1 station data and its gridded dataset (5° × 5°) for 1850–2024, into which nearly 3000 additional stations were merged. Building on this, high‑resolution (0.5° × 0.5°) land surface air temperature (C‑LSAT HRv1) and diurnal temperature range (C‑LDTR HRv1) datasets for 1901–2023 were produced via thin-plate spline interpolation of the climatology fields and adjusted inverse distance weighted interpolation of the anomaly fields.
