Abstract
The results of the analysis of differences in climate norms in different months of the year during the modern climate warming period (1990–2023) and the preceding period (1956–1989) in the high latitudes of the Northern and Southern hemispheres (60–90°N and 60–90°S) are presented. A comparative analysis of changes in temperature gradient was conducted for near-equatorial (0–10°N and 0–10°S) and polar (65–90°N and 65–90°S) latitudes of the Northern and Southern hemispheres. The decrease in the gradient value was most significant in transitional seasons of the year and especially in autumn. In the Southern hemisphere, the largest decrease in temperature gradient occurred in winter and spring (June–October). The possible causes of climate warming in the high latitudes of the Northern and Southern hemispheres are considered.
