Global average temperature 1850 - 2020

 

A few letters and articles in the press of late prompted some research into the temperature records for 2020.

NASA said 2020 was essentially equal with 2016 as the hottest year on record.

National Oceanic Atmospheric Administration, said last year came in a close second or third as the hottest ever.

The European Copernicus group also called 2020 an essential tie for hottest year, with 2016 warmer by an insignificant fraction.

Japan's Weather Agency put 2020 as warmer than 2016.

The World Meteorological Organization, the UK Met Office and Berkeley Earth's monitoring team, all had 2016 just ahead of 2020.

All the monitoring agencies agree the six warmest years on record have been the six years since 2015.

The 10 warmest years on record have all occurred since 2005.

Earth has now warmed 1.2 degrees Celsius since pre-industrial times and is adding another 0.2 degrees Celsius each decade.

The science surely is irrefutable?
