The 1st December 2021 marked the 62nd anniversary of the signing of the Antarctic Treaty by the twelve countries whose scientists had been active in and around Antarctica during the International Geophysical Year (IGY) of 1957-58. The total number of Parties to the Treaty is now 54. Among the most important agreements the treaty states that "Antarctica shall be used for peaceful purposes only” (Article I); “Freedom of scientific investigation in Antarctica and cooperation toward that end… shall continue” (Art. II); “Scientific observations and results from Antarctica shall be exchanged and made freely available” (Art. III) / On the 4th December 2021 a total eclipse of the sun will be visible in Antarctica and the Southern Ocean. The instant of greatest eclipse occurs over the Weddell Sea at 07:33:27 UTC and its duration will be 1 minute 54 seconds. / Albatross in the Falkland Islands seem to be affected by warmer water temperatures which made up to 8% of albatross couples split up. Either warming waters force the birds to hunt for longer and fly further or stress hormones go up in harsher environments, such as when waters are warmer. / Linking up with the previous episode, inflow of warm water from the Atlantic influences the temperatures in the Arctic Ocean: a phenomenon called Atlantification. At the German Alfred Wegener Institute (AWI) weekly CryoSat data with daily SMOS data are merged to generate a weekly-averaged product every day on ice volume in the Arctic. / The Arctic Ocean has been warming since the beginning of the 1900s due to warmer water flowing from the Atlantic Ocean. The Arctic Ocean temperature has risen by approximately 2 degrees Celsius, while sea ice has retreated and salinity has increased. / Arctic warming means that the thawing permafrost could release bacteria, viruses, chemicals and other substances stored in the frozen soil . / The famed Northern Sea Route this year has been closing up earlier than expected as the ice has trapped ships and icebreakers have had to come to their rescue.

POLAR NEWSREEL In episode 141 we promised you an update on the 40th annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). Unfortunately, for the 5th year in a row there was no progress on the proposed Marine Protected Areas. // A new study documents the formation in 2020 of a 3,000-square-kilometer rift in the oldest and thickest Arctic ice north of Ellesmere Island. This is another sign of the rapid changes taking place in the Arctic, according to researchers. // A very instructive and entertaining short video on Antarctic krill has been published by the WWF: enjoy the view!

CLIMATE COP26 IN GLASGOW The "greenhouse effect" was described in 1824 by the French physicist Joseph Fourier and in 1896 the Swedish chemist Svante Arrhenius calculated a doubling of CO2 due to industrial-age coal burning will raise the global temperature by several degrees Celsius. In spite of these early discoveries it took until 1988 for the members of the World Meteorological Organization and the United Nations Environment Programme to establish the UN Framework Convention on Climate change (UNFCCC) to tackle anthropogenic climate change. In the course of its history the UNFCCC has held many Conferences of the Parties or COP's, the most famous of which are the Kyoto Protocol of 2005 and the Paris Agreement of 2015. This year the 26th COP was held in Glasgow (UK) and has resulted in a declaration that disappointed the advocates of the phasing out of coal. However, COP26 made history by directly mentioning fossil fuels, a first time in a UN climate agreement.
