For the first time, scientists released data visualizations showing global temperature anomalies since 1950. This visualization shows surface temperature anomalies from 1950 through November, 1998. The 1998 warmth was associated partly with a strong El Nino that warmed the air over the eastern tropical Pacific Ocean in the first half of the year and in turn affected weather around the world. This visualization shows surface temperature anomalies from 1950 through November, 1998.
Scientists use data from rural stations to correct for urban influences on reported temperatures.
Red and yellow colors indicate warmer than normal conditions and blue indicates cooler than normal conditions. This is NOT a finished production and contains no narration.
