Greta Thunberg has called for action after NASA declared 2020 the hottest year on record.
The 18-year-old environmental activist said the world is facing a ‘climate emergency’ and she called for people to ‘be the change’ and ‘spread awareness’.
Analysis by NASA’s Goddard Institute for Space Studies (GISS) in New York found that 2020 edged out 2016 as the hottest year ever by less than a tenth of a degree, which falls within the study’s margin for error and therefore effectively renders the years the joint-hottest on record.
NASA said 2020’s globally averaged temperature was 1.84 degrees Fahrenheit (1.02 degrees Celsius) warmer than the baseline 1951-1980 mean.
The US National Oceanic and Atmospheric Administration (Noaa) and the Met Office both put 2020 in a close second place behind 2016, due to slightly different calculation methods.
GISS Director Gavin Schmidt said: “The last seven years have been the warmest seven years on record, typifying the ongoing and dramatic warming trend.
“Whether one year is a record or not is not really that important – the important things are long-term trends. With these trends, and as the human impact on the climate increases, we have to expect that records will continue to be broken.”
