- CLAIM: The Arctic: A Delicate Icy Ecosystem. EUROPEAN SPACE AGENCY (ESA) OCTOBER 7, 2020, The Arctic is one of the most rapidly changing regions in the world. Diminishing sea ice, thawing permafrost and melting glaciers are all direct effects of rising global temperatures – driven by human-made emissions. Learn more about how satellites flying 800 km above our heads can help us monitor and understand the changes occurring in this remote region.
RESPONSE (1) That the Arctic is rapidly changing means only that you have found a region that is rapidly changing and not that it is a feature of rising global mean temperature that can and must be managed and controlled with human interference. (2) The Arctic sea ice goes through a violent seasonal cycle in which more than 90% of the winter sea ice is gone by September and it is true that September minimum sea ice is declining from year to year at a rate of about 1% per year. The assumption that this decline is caused by global warming is not supported by the data as shown in related posts: LINK: https://tambonthongchai.com/2020/09/25/list-of-arctic-sea-ice-posts/ .
RESPONSE (2): Thawing permafrost and melting glaciers. Permafrost thaw is projected and not observed. Some localized thaw events in Siberia are localized events and if these have climate implications they must be understood as internal climate variability because of their geographical and temporal limitations. Global warming may play a partial role in glacial melt there in terms of meltwater ponds that form on top of the ice sheet during June, July, and August but this role of the atmosphere in the total melt rate of 200 to 350 gigatons per year is insignificant as the melt is mostly a result of geothermal heat flux from geological activity under the ice sheet as described in a related post: LINK: https://tambonthongchai.com/2020/11/07/climate-change-threatens-polar-ice/
