    Grim news indeed – the world needs to be on it’s toes with countries having leaders of purpose. Not denying rats at the helm. Sad times indeed. Let’s hope for a change. TIME TO HANDOVER ???

    Per NASA research the arctic was ice free in summer about 4500 years BP. Last I checked the world did not end. https://en.wikipedia.org/wiki/Dendroclimatology#/media/File:Yamal50.gif temperature reconstruction using tree rings, we have been in a cold period for about 3500 years on average with hot spells like the medieval warm period thrown in. Perhaps we are simply going back to the warm period from 7000 to 5000 years before the present.

      Backtracking on the Milankovitch cycles then you think. Why not, that Milankovitch was always overrated with his crummy cycles going forwards, backwards, sideways, upside down, whichever way suits you best. I’d never ride a Milankovitch cycle.

      Not even vaguely astute, as usual. Naive readers should note:

      He/she/it doesn’t explain what a graph of tree rings from now–living Yamal Peninsula and Siberian conifers tells us what about Arctic Ocean ice cover.

      The “medieval warm period” was local, not global.[1]

      And the graph he links to doesn’t go past 5,030 years ago, it says nothing about a warm period 6,000 or 7,000 years ago.

      This is at least the third time you have posted that dendrochronology chart pretending it is something that it isn’t. This is a report from one patch of forest on the entire planet.

      Climate research involves looking at many, many suites of climate proxies from different disciplines. They variously measure isotope ratios over time, varve sediments, the size of stomata on preserved leaves, root lengths, foraminifera, glacial residue. They take into account proximity to magma chambers and rifts, crustal uplift, sediments formed under sea ice, temporary cooling from ancient erupts and many other confounding processes.
