  1. This is the best tl;dr I could make, [original](https://www.upi.com/Science_News/2020/01/08/Without-sea-ice-Arctic-permafrost-more-likely-to-thaw/2031578511773/) reduced by 77%. (I’m a bot)

    > Jan. 8 – As the Arctic loses its sea ice, new research suggests permafrost is more likely to thaw and release carbon dioxide into the atmosphere.

    > It's not clear exactly why sea ice has such strong impact on permafrost stability, but researchers suspect a lack of sea ice allows warmer water and currents to exert a greater influence on the atmosphere, causing warm, wet air to travel farther inland across Siberia.

    > According to scientists, the influx of moisture triggered by a loss of sea ice likely boosted snow totals in Siberia, insulating the ground against the winter cold and making permafrost melting more likely.

  2. We can expect at least one ice free month in the arctic by 2023-2025 with an additional month each year thereafter.

  3. No way this could have knock on affects for us, good thing all those climate models were wrong or this could be really bad. /S – capital S because of the overwhelming amount of climate deniers on reddit these days.

  4. Article Permafrost most likely to happen when artic free of ice … yeah ok, good to know that ice melts when there’s melted ice
