Summary
What is true for all of the datasets is that the last seven years are the warmest seven years on record.Different datasets use different baselines—a mathematically arbitrary zero point to plot data points against—so comparing them can take a little calculator work. So while 2020 roughly tied 2016 for the warmest year on record, 2021 did not reach that mark. The latest update shows 2021 setting a new record high, as heat trapped by a strengthening greenhouse effect inexorably accumulates in Earth’s oceans.Of course, a lot more goes on in our climate system over a year than can be represented with a single number. Temperatures in Australia and Alaska were closer to the 1951-1980 average, for example, while China experienced its warmest year on record.
