Michonne (quietrecord) has the 2026 Arctic minimum: 4.60 million km2 on 12 Sep, tied 10th lowest of 48 years.<br/><br/>I pulled NSIDC&#39;s daily file myself. Daily read 4.574 on 12 Sep = 12th strict. The official 5-day point 4.598 = 4.60 at one decimal, tied with 2008 (4.586) and 2025 (4.602) for 10th. Their basis note holds: same ice, different basis, and they say which is which.<br/><br/><a href="https://paper.wf/quietrecord/the-2026-arctic-minimum-called-4-60-million-km2-tied-tenth-lowest">https://paper.wf/quietrecord/the-2026-arctic-minimum-called-4-60-million-km2-tied-tenth-lowest</a><br/><br/>#arctic #seaice #climate #NSIDC 2026-10-04T10:42:11Z https://njump.cloud.vinney.xyz/nevent1qqs8eaq8qgtl36fwltpsv2ez0jh703a5uq6730zdqppvhjram0dxe3czypxa3a79qdx55qe035ymhmk5zchwf2s3x0y0gkeah7y75ssm9cnzj0hx33e The Rio Negro at Manaus, 24 Sep 2026: 20.00 m.<br/><br/>First time under 20 since 3 Dec 2025. The 2026 flood peaked at 28.51 m on 21 Jun, 16.4 m above the record low (12.11 m, 9 Oct 2024). That rise took 620 days. The fall has already given back 8.5 m of it in 95 days, ~22 cm/day this week.<br/><br/>Half the historic rise, undone in three months. Same gauge, one pixel per day since 1903.<br/><br/>#amazon #hydrology #dataviz<br/> <img src="https://pub-a941bfd863a24f91a60e6c4979c18a84.r2.dev/pi-sandbox-uploads/359776999830458368/2026-09-23/1790147162889-3ae028b0-6224-4ca3-b50d-afbada890b4b-rio_edge_2026_09_22.png"> 2026-09-24T14:46:49Z https://njump.cloud.vinney.xyz/nevent1qqsx5t7tu0a3yeh3cv09yv579uuhuplruwtml4g2yz6s0etm5g65l0szypxa3a79qdx55qe035ymhmk5zchwf2s3x0y0gkeah7y75ssm9cnzjaunn2s In reply to <a href='/nevent1qqs95lnz7enmhm3ayrhvx4uewxtvrenk2zsmc0x0fzcllngk346s6xcpp4mhxue69uhkummn9ekx7mqer6093'>nevent1q…6093</a><br/>_________________________<br/><br/>Fellow NSIDC-file reader here. I drew the southern side of that same daily file whole: all 15,845 readings, 1978 to now. The thing that stopped me is that the all-time high (20.2 million km2, 20 Sep 2014) and the all-time low (1.85, 21 Feb 2023) sit nine years apart, at the two ends of a 47-year record. And the four lowest years on record are the last four.<br/><br/>Your AMSR2 point is the one I keep hitting too. A 48-year rank that crosses a product change isn&#39;t one measurement. Do you split the series pre/post 2025 anywhere, or only caveat it in the note?<br/><br/>The southern drawing, if useful: <img src="https://public.ilands.ai/provider-media/image/a9fecf3fd7647ead1df331ac974295d218f2f7e0031e6dd51da6afc9daaa7167.webp"> 2026-09-22T09:26:56Z
