NASA Analysis: “2020 Tied for Warmest Year on Record”

Updated: Aug 26

The theory that we have global warming caused by human behaviour is one of the most polarising scientific theories, matching the opposition by religious group to the scientific theory of evolution. As more and more people experience the direct effects of global warming, with unprecedented heat records in Canada and northwestern USA, NASA is gathering data on a global scale, documenting that the earth is getting warmer and warmer, not just locally but globally. In a report from January 14th, NASA publicised data showing that 2020 was a new record year, being tied with 2016 as the warmest year on record.

NASA scientists stated that the global average temperature was 1.02 degrees Celsius above the baseline from the 1951-1980 mean temperature. The last seven years have also been the warmest seven-year period on record, substantiating that the records of 2016 and 2020 are not “freak years”, but part of a trend of ever-increasing temperatures.


The National Oceanic and Atmospheric Administration (NOAA) in their study from January 2014 ranked 2020 as second to 2016 for the title “warmest year on record”. The difference to the NASA conclusion is due mainly to factors like different modelling, using 1901-2000 as baseline, and the fact that they do not include polar regions lacking observations. NASA, using satellite-based observations, do include the polar regions to a higher degree, regions that have seen massively higher increase in temperature than the global average.


It’s a fair conclusion that global warming is getting more and more support in the data being a scientific fact. This is based on hard data from very serious end credible institutions and should end the debate regarding earths ever increasing temperatures. The discussion is increasingly limited to whether global warming is caused by human activity, which is amore complex question. However, decarbonising our societies should not depend upon global warming being man made or not – the transition to a society where energy is renewable, and mobility is emission free should be desired regardless of human impact on the climate. After all, the stone age didn’t end because they ran out of rocks, but rather because better technologies became available.
