The story so far: In March, parts of eastern Antarctica recorded extremely high temperatures that were around 30 degrees Celsius above normal, sounding alarm bells for rapidly progressing climate change. The Concordia base at Antarctica registered a record -11.5 degrees Celsius (11.3 Fahrenheit) on March 18. According to meteorologist Etienne Kapikian, the previous record was 3.7°C on December 17, 2016.
The World Meteorological Organisation has declared 2021 as one of the seven warmest years on record. The average global temperature last year was over 1.11⁰C higher than the pre-industrial (1850-1900) levels. According to the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA), the earth’s global average surface temperature in 2021 tied with 2018 to be the sixth warmest year on record.

Canada
In 2021, Canada recorded a shocking temperature of nearly 50⁰C, similar to that of the hot Saharan Desert.
The temperature in Lytton, British Columbia reached 49.5⁰C in June 2021, breaking the daily and all-time temperature records. This topped Canada’s previous record of 45°C set in July 1937 in Yellow Grass and Midale, Saskatchewan.
The exceptionally high temperature in British Columbia was part of a larger heatwave that hit the western coast of North America in June 2021. On June 27, Seattle recorded 40°C, the city’s highest temperature ever recorded on any day of the year.
