Did you read the whole article? Ok, 2021 has been better than the last 18 years, but still below the long-term average (https://www.severe-weather.eu/wp-content/gallery/cryosphere/...), so "largest coverage" it is not - and also one good year doesn't mean that it will keep getting better.

It turns out that there are three dimensions. Arctic sea ice volume keeps dropping, faster and faster.

Funny definition of "now". Your linked article was from 8 months ago, you know, when it was winter.

As for the real "now", if you care to look at a graph of the last few years and as well as inter-decile and median from 1981-2020, it's blatantly obvious that both volume and extent are well below average, and on a long, steady, downward trend.

If you don't see the decreasing trend in the 1980s, 1990s, 2000s, 2010s mean curves, I can't help you.

Another thing missing from this measurement is this is the Arctic sea ice area. The Arctic sea ice volume is trending almost linearly towards 0.

Thanks for the link to the news by Arctic scientists.

In this article [1] they wrote that the shift to more rainfall than snow in the Arctic is now predicted to occur between 2050 to 2080 (whereas the old models predicted this to occur between 2070 to 2090).

Interesting but alarming.
