[Objective] Climate change directly affects global wind speed changes and the efficiency of wind energy resource utilization. Analyzing wind speed historical changes is one of the important topics for climate change response, efficient resource utilization, ecological security management, and sustainable social development. [Methods] Using the ERA5-Land grid reanalysis wind speed dataset at the 0.1° resolution from the European Center for Medium Range Weather Forecasts (ECMWF) and methods such as least squares, Theil-Sen slope estimation, and MK trend test to study the annual, seasonal, and monthly average wind speed trends and the evolution of suitable wind power areas over the past 72 years from 1950 to 2021 worldwide. [Results] (1) The global mean land surface wind speed increases slightly at an overall rate of 0.020 m/(s·10a) from 1950 to 2021. (2) The surface wind speed changes on a global scale exhibit significant spatial differences, especially remarkable in Africa and Antarctica in comparison with other continents.
