You notice that in the graph you provided the link for, the lines for 2016, 2017, 2018, 2019 and 2020 are way below the mean value of 1981 to 2000? For the years from 2016 to 2020 there's an about sigma 4 deviation to the mean of 1981 to 2000 Do you know how unlikely this makes this curves to just be random variation? There's an about 11% degradation in surface area, in just about 20 years.
