Urban Microclimates in a Warming World: Land Surface Temperature (LST) Trends Across Ten Major Cities on Seven Continents
Overview
Paper Summary
This study used satellite data to compare temperature trends in ten major cities across seven continents, finding that urban areas are generally warming, especially at night, and that green spaces have a cooling effect. Industrial areas and airports were hotspots, while green spaces and water bodies tended to be cooler.
Explain Like I'm Five
Cities are getting warmer, especially at night, and green spaces help cool things down. The study looked at satellite data from ten big cities around the world.

Rating Explanation
This study provides a valuable comparative analysis of urban heat island effects across diverse geographical regions. The use of MODIS satellite data and Google Earth Engine allows for a large-scale, long-term analysis, which is a significant strength. While the study acknowledges limitations in satellite data accuracy and the complexity of influencing factors, its findings offer valuable insights for urban planning and climate change adaptation.
