Does any one know anything about this chart displayed on NoTrickZone How can they estimate sea ice thickness back beyond satellite data? Sorry about the picture size. How can I make it smaller?  |

Good question. I was thinking ships logs which were very weather centered. Remember, the search for a Northwest Passage was a top priority for all of the maritime powers! I found this: phys.org/news/2019-08-century-arctic-sea-ice-volume.html |

Interesting Blus, contradicts the above very strongly.
I trust the satellite period but little else. there is little doubt the period up to the 50's were low and the older data that was use to build the above or the other would be very open to interpretation.
Open water behind ice is a feature of modern observations from satellite at the end of the summer season.

Open water behind ice is a feature of modern observations from satellite at the end of the summer season. No matter what chart we look at, they all represent an extremely short temporal record of the ice. The LIA alone must have caused an increased sea ice extent compared to today that has since declined. |

The big ones are select La Nina years. |

Looks like Arctic ice extent has passed its 2021 minimum. Another year, another non-ice free Arctic. sunshinehours.net/ |

So, ten years had lower Arctic Ice Extent than 2021 according to sunshinehours. Does this mean the cryosphere is no longer writhing in agony?

Arctic temperatures seem to be exhibiting a slight pause. The graph below shows Artic temperatures from 1920 to 2021 The AMO chart for the same period is also shown below. The periods of Maximum AMO have been boxed out. They would appear to be linked to a corresponding rise in Arctic temperatures. If this is true we might expect to see Arctic temperatures falling as the AMO starts to fall. We can only wait and see. The Sea Ice extend is shown in the last graph. It appears to have bottomed out since 2007 But we only have 14 years of data. There was a big recovery in sea ice in 2021. Will this continue in 2022 if the AMO starts to fall? Again we will have to wait and see   |

Vladamir is just quoting HR Haldeman, who was quoting Teddy. “If you've got them by the balls, their hearts and minds will follow.”  |
