Recently released by NASA this visualization presents monthly global temperature anomalies between the years 1880-2021. Whilst our CO2 levels have increased 60% since the 1950’s it’s interesting to see the effects of this particularly in the two decades. Global climate change targets are attempting to minimize a temperature increase to 1.5deg C
These temperatures are based on the GISS Surface Temperature Analysis (GISTEMP v4), an estimate of global surface temperature change. Anomalies are defined relative to a base period of 1951-1980.
The Goddard Institute of Space Studies (GISS) is a NASA laboratory managed by the Earth Sciences Division of the agency’s Goddard Space Flight Center in Greenbelt, Maryland. The laboratory is affiliated with Columbia University’s Earth Institute and School of Engineering and Applied Science in New York.
The ‘climate spiral’ is a visualization designed by climate scientist Ed Hawkins from the National Centre for Atmospheric Science, University of Reading. Climate spiral visualizations have been widely distributed, a version was even part of the opening ceremony of the Rio de Janeiro Olympics.
