Well, it’s official: 2021 was one of the planet’s seven hottest years since records began, the World Meteorological Organization (WMO) declared this week. The year was about 1.11℃ above pre-industrial levels – the seventh year in a row that the average global temperature rise edged over 1℃.
The WMO report echoes two separate official US analyses released last week that found 2021 was the sixth hottest year on record, tied with 2018.
For many of us in Australia and overseas, however, 2021 may have felt generally colder and rainier than usual. This is because of the effect of back-to-back La Niña events, a natural phenomenon that brings cooler, rainier weather in our region.
