Look at this dip during the last week !

Could it be an anomaly with satellite imaging, a random statistical blip, or is something huge just about to start ?

The “big” thing then would be if the result for each year was successively lower.

graph is from https://nsidc.org/sea-ice-today/sea-ice-tools/charctic-interactive-sea-ice-graph

that grey area shows 10%-90% range. The big thing is that since 2022, ice extents have deviated strongly from that ultra narrow band. Previously year to year and successive moves, were fairly random above/below that range.

    Yep. I didn't mean to imply something wasn't happening, but that something isn't what OP pointed at, and that something is evidence of climate change.

    People need to learn that its a slow decline. It's disastrous, but it looks like worsening wildfires each year. More tornados in Iowa and Minnesota. Lower crop yields. Beaches getting smaller by inches, ocean front property values declining and insurance rates increasing. More intense variations in weather and more difficultly forecasting.

    But there are also discussions and predictions about numerous potential tipping points and positive feedback loops.

    Even those don't mean it's straight for rock bottom.

    A tipping point means a point of no return. It will never improve beyond that point. Extent of ice won't show you that. Otherwise when the extent is at its lowest in March, it would never come back.
