Temperatures in São Paulo have increased significantly more than the global average over the past 125 years. While the global average temperature has risen by approximately 1.2°C since 1900, and the Earth's surface by 2°C, the daily maximum temperature in São Paulo has increased by 2.4°C, with the most significant increase occurring after 1950. The daily minimum temperature has risen by 2.8°C since the beginning of the 20th century. These observations were presented by Humberto Ribeiro da Rocha, a professor at the Institute of Astronomy, Geophysics and Atmospheric Sciences at the University of São Paulo (IAG-USP). Research conducted by Rocha and other researchers has shown that the temperature disparities in São Paulo are related to the urban heat island effect, caused by the replacement of vegetation with construction materials like asphalt and concrete. A new study analyzed the relationship between the urban heat island and vegetation cover in 70 cities in São Paulo state using satellite data from 2013 to 2025.
