Silicate rock weathering maintains a stable and long-term absorption of CO2. However, the magnitude, spatial pattern, and evolution characteristics of global silicate rock weathering carbon sink (SCS) remain unclear. To solve this problem, based on high-precision hydrometeorological data (1996-2017) and CMIP5 data (2041-2060), using the Celine model, we calculated the global silicate rock weathering carbon sink flux (SCSF) magnitude and spatio-temporal distribution for 1996-2017. We also predicted the SCSF under two future greenhouse gas emission scenarios (RCP 4.5 and RCP 8.5). Then, we produced a spatial data set (0.5 x 0.5) of global SCSF from 1996 to 2017 and found that the global average annual SCSF was 1.67 t/km(2)/yr, and the SCS was 127.11 Tg/yr. In particular, Brazil's silicate rock contribution accounts for nearly a quarter of the global SCS (24.41%). Although the GEM-CO2 model is now widely used, the SCSF, without considering the temperature, may be overestimated by 5.4%, and the maximum contribution of temperature to it can reach 240 kg/km(2)/yr. Moreover, the global SCS is now showing a downward trend, but the global emission of greenhouse gases in the future (2041-2060) will continue to increase the carbon sink capacity (23.8%) due to temperature changes. In summary, we have produced a set of high-resolution spatiotemporal data of the past and the future. The above results fill up the large-scale data gap of SCSF and provide a scientific basis for quantitatively assessing the impact of climate change on SCS.
