Urbanization significantly intensifies continental- to regional-scale warming, particularly in rapidly urbanizing regions like Asia. While urbanization contributes only about 2% to global warming, its impact on large-scale climate is becoming more detectable. Using satellite-derived land surface temperature (LST) data and dynamic urban area estimates, the study shows that urban areas influence LST and air temperature trends. Urbanization's effect is most pronounced in regions with high urban growth rates, such as China, India, and the United States. Future urban expansion is expected to further increase these impacts, with projections indicating a potential 0.16 K increase in North America and Europe by 2100 under high-emission scenarios. The study emphasizes the need to include urbanization in climate change assessments at all scales, as it has non-negligible regional and even continental impacts. Urbanization's influence on climate is not just local but also affects large-scale patterns, highlighting the importance of considering urban areas in climate models and assessments. The findings challenge the traditional view of urbanization as a local phenomenon and underscore its role in global climate dynamics.Urbanization significantly intensifies continental- to regional-scale warming, particularly in rapidly urbanizing regions like Asia.
