Look at this dip during the last week !
Source : ClimateReanalyser.org and NSIDC
Could it be an anomaly with satellite imaging, a random statistical blip, or is something huge just about to start ?

    I have no idea what this data is, but I have the gut feeling that we are fucked

        That we are not completely fucked yet on climate change has been false for quite a while.

        Factoring in our societies, there was never any chance we would change, and feedback loops are already amplifying, that is what will sink us. The permafrost melting will overwhelm the planet’s ability to absorb carbon. Yay for anaroebic life!

      This has been my gut reaction for the last years of climate related news, lately extending to all other news as well….

          Binface just showed us a path to reform candidates though. He got solid numbers, 26 percent or something. With a blended joke/real candidate, we could win.

          Regardless the US needs this organization of joke candidates that the UK has. I forget what they call it. Loony something.

    As someone who doesn’t have a background in climate science, I think it’s a really bad idea to look at this and start panicking without context. Just saying

    With the super el niño I think this year is supposed to be the warmest on record (so far) so unfortunately I would not be surprised if the lack of sea ice is more concentrated in the northern hemisphere.

    I’ve been following sea ice extent for a long time and the number one thing I’ve learned is to not get caught up by any given blip. Sea ice is a complex, slow moving system, so any wobble on the line in a given year is basically meaningless. Look at the year to year and decade to decade trends.

      Mostly for shits and giggles, I told an LLM to find and look into the data.

      There is already one strong confirmation: climate scientist Zachary Labe has put up a temporary graphic specifically “to monitor the ongoing record low Antarctic sea ice extent,” updated August 14, 2026. So what you’re seeing is real enough to have caught specialist attention, not merely a Climate Reanalyzer rendering quirk.

      I pulled the underlying NSIDC Sea Ice Index v4 daily file rather than relying only on the plotted line. The reversal is substantial: extent rose to about 16.369 million km² on August 4, then fell to 15.955 million km² by August 11—a loss of roughly 414,000 km² in seven days—before ticking back up on August 12–13.

      I’m checking the full 1979–2026 record now to see how unusual a week-long decline of that size is at this point in the Antarctic winter, rather than just calling it unusual by eyeballing the graph.

      I pulled the underlying NSIDC Sea Ice Index v4 daily data that Climate Reanalyzer uses. Climate Reanalyzer itself plots a 5-day mean, which is important because it means the sharp-looking downturn isn’t just one bad satellite day.

      I ran the same calculation over the historical NSIDC daily record, using 1988 onward for a clean daily-sampling comparison. The largest previous early-August drawdown in the 5-day-smoothed series was only about 50,000 km². The 2026 decline is therefore roughly six times larger than the next-largest comparable early-August reversal I find.

      That last point is particularly interesting because the month didn’t begin this way. On August 2, the UK Met Office reported Antarctic extent at 16.65 million km², only the 4th-lowest for the date. July had actually been gaining ice at 76,000 km²/day, slightly faster than the climatological 72,000 km²/day. So this is not simply “2026 has been steadily failing to freeze.” There really was an abrupt change in trajectory during the first half of August.

      You’re now the second or third comment I’ve read to mention this. Has anyone actually pointed these blips out though? I’d like to see them.

        There are examples even in this graphic but slightly difficult to see due to how it’s designed. Due left from the highlighted point you have one such reversal (albeit slightly smaller than this one).
