The Northern Hemisphere had the most significant temperature increase from the median temperature anomaly from the 30 year average temperature (1961-1990).
In 2015-2019, global average temperature in the Northern Hemisphere was 0.76 degrees Celsius greater than in 30 year average temperature (1961 – 1990). This compares to just 0.46 in Tropics.
