Since the 1950s, global temperature data has shown a slight increase, but some scientists questioned its accuracy due to urban thermometer placements. Satellites launched in 1979 aimed to provide comprehensive data but initially showed cooling, conflicting with thermometer data. An error in satellite calculations was found and corrected, aligning both data sources to show a warming trend. The scientific community now largely agrees on global warming, though some skepticism remains.
