proving that yes, as a matter of fact, we lost over 35% of that Sweet Millennial ice.

16% loss/decade, or 3100 km³ from the COP20 (Lima) base of 19,500 km³ reading from the 30-yr avg graph …
Arctic sea ice this week at 5.3 k km³. This week saw daily sea ice volume at 5.3 & its 30-year average at 16.3. This was also an All-Time Low for the latter. The annual average is approaching 12,900 km³. Odds are, COP 30 in the Amazon this November will change absolutely nothing.
Latest projections estimate the minimum at around 3,897 km³, making it the 2nd lowest after 2012's 3,673 km³. The 2025 annual mean could still drop below 2017's record low of 12,800 km³,
so 53% loss of arctic ice volume since 1979.... or 25,400 kilometers cubed to 13,600

What doesn't get mentioned in the media is there's 1200 gigatons of pressurized methane in the world's largest ocean shelf - the subsea permafrost of the East Siberian Arctic Shelf!
The taliks have melted down to that permafrost for 50 gigatons being triggered already - soon to be released as an "abrupt eruption" that will soon double atmospheric temps within the decade (could happen any day though). The arctic ice is melting from below due to the 500 extra Zetta joules of heat in the ocean (hence the hurricane in Jamaica being so much more powerful due to ocean heat).
