Glacial episodes of a freshwater Arctic Ocean covered by a thick ice shelf
Following early hypotheses about the possible existence of Arctic ice shelves in the past1–3, the observation of specific erosional features as deep as 1,000 metres below the current sea level confirmed the presence of a thick layer of ice on the Lomonosov Ridge in the central Arctic Ocean and elsewhere4–6. Recent modelling studies have addressed how an ice shelf may have built up in glacial periods, covering most of the Arctic Ocean7,8. So far,…
During the temperature maximum in the Holocene before 11,700 to 8,200 years, the Arctic was about nine degrees warmer than today. And this, although the CO2 content at that time was just 260 ppm. Since then, the region cooled down further. For example, the glaciers on Svalbard did not melt down completely at that time. For several years, the climate apocalyptic people have not been tired of warning of the de-icing of the Arctic. The rising CO2 v…
New Study: The Arctic Was 9°C Warmer Than Today During the Holocene Thermal Maximum
Holocene (11,700 to 8,200 years ago) Arctic (Svalbard) temperatures “were up to 9°C higher than today” according to the authors of a new Nature journal study. At that time CO2 was thought to only hover around 260 ppm.
New Study: The Arctic Was 9°C Warmer Than Today During The Holocene Thermal Maximum
Holocene (11,700 to 8,200 years ago) Arctic (Svalbard) temperatures “were up to 9°C higher than today” according to the authors of a new Nature journal study. At that time CO2 was thought to only hover around 260 ppm. Svalbard then cooled as CO2 rose for the next 8,000 years – a negative correlation that wholly contradicts the rising-CO2-drives-Arctic-warmth narrative. Nonetheless, climate models are predicated on the assumption rising human CO2…
