    As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. How inconvenient! The Arctic Ice is still there, and it's stopped shrinking.
    If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere.
    The climate crisis/emergency/apocalypse is make-believe.
    Multiyear ice is an unproductive habitat as far as marine organisms are concerned: first year (seasonal) ice over continental shelves is the most productive and this is where the vast majority of polar bears, seals, fish, whales, and sea birds are found. Therefore the decline of extremely thick multiyear ice (>4 years old) could be seen as an unconcerning development with regards to the wildlife in the region, especially since 2-3 year old ice that can be used as a resting/hunting platform for seals and polar bears hasn't declined in summer since 2007. In fact, biologically, the Arctic is in good shape with all its regions showing a positive trend in primary productivity over an extended period (2003-2022). This has resulted in more food for seals, walruses, bowhead whales and polar bears, which are hence maintaining or expanding their populations.
    There's no "death spiral" in the region as some people reported. In fact, there is, as I say, no evidence of any crisis/emergency. That is silly nonsense designed to scare people.

    You guys had no idea that the oceans would take off like they did. How about an update? Seeing as we just skipped ahead about 10 years on climate change in one shot last year

    Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.
