Nicola Scafetta – Is the urban heat island effect driving temperature statistics?


13th International EIKE Climate and Energy Conference (IKEK-13) on November 12th and 13th 2021 in Munich.

Prof. Nicola Scafetta, University of Naples Federico II, Department of Earth Sciences.
The speaker investigates whether the known heating of dense settlements is the true reason for measured temperature increases, as the measuring sensors are usually located in growing cities over time. Thus, temperatures measured by satellites are typically somewhat lower than the values output by ground stations.
The Intergovernmental Panel on Climate Change (IPCC) claims that the air layers near the ground heated up by 1.5°C between 1850 and 1900.
The problem of heat islands in settlements is well known and is supposedly compensated by so-called “homogenisations”. Instead, the warming in the 20th century is clearly overestimated.
