Temperature Anomalies in May 2021 Emergency Response Coordination Centre (ERCC) – DG ECHO Daily Map | 14/06/2021 World | Temperature Anomalies in May 2021 The global average temperature for May 2021 was about 0.26ºC higher than the 1991-2020 average ARCTIC OCEAN for the same month. Globally, and despite lower regional temperatures e.g., across parts of Europe, May 2021 was warmer than any other May in the 1979-2015 period. NORTH Temperatures were above average over northern ATLANTIC Africa, the Middle East, The Caucasus, Central Asia OCEAN NORTH and most of Siberia. Other regions of the world with PACIFIC OCEAN above-average temperatures include northern Greenland, western Alaska and western USA, south- east Asia, and western Australia. Antarctica, in the vicinity of the Weddell Sea, also experienced above- average temperatures. During May 2021, below-average temperatures occurred across most of Europe (except for southern Europe), most Canada, India, north-eastern Asia, southern Africa, over most East and parts of West Antarctica.

  • The Antarctic Treaty System And
    The Antarctic Treaty System and Law During the first half of the 20th century a series of territorial claims were made to parts of Antarctica, including New Zealand's claim to the Ross Dependency in 1923. These claims created significant international political tension over Antarctica which was compounded by military activities in the region by several nations during the Second World War. These tensions were eased by the International Geophysical Year (IGY) of 1957-58, the first substantial multi-national programme of scientific research in Antarctica. The IGY was pivotal not only in recognising the scientific value of Antarctica, but also in promoting co- operation among nations active in the region. The outstanding success of the IGY led to a series of negotiations to find a solution to the political disputes surrounding the continent. The outcome to these negotiations was the Antarctic Treaty. The Antarctic Treaty The Antarctic Treaty was signed in Washington on 1 December 1959 by the twelve nations that had been active during the IGY (Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, United Kingdom, United States and USSR). It entered into force on 23 June 1961. The Treaty, which applies to all land and ice-shelves south of 60° South latitude, is remarkably short for an international agreement – just 14 articles long. The twelve nations that adopted the Treaty in 1959 recognised that "it is in the interests of all mankind that Antarctica shall continue forever to be used exclusively for peaceful purposes and shall not become the scene or object of international discord".

  • Consensus Statement
    Arctic Climate Forum Consensus Statement 2020-2021 Arctic Winter Seasonal Climate Outlook (along with a summary of 2020 Arctic Summer Season) CONTEXT Arctic temperatures continue to warm at more than twice the global mean. Annual surface air temperatures over the last 5 years (2016–2020) in the Arctic (60°–85°N) have been the highest in the time series of observations for 1936-20201. Though the extent of winter sea-ice approached the median of the last 40 years, both the extent and the volume of Arctic sea-ice present in September 2020 were the second lowest since 1979 (with 2012 holding minimum records)2. To support Arctic decision makers in this changing climate, the recently established Arctic Climate Forum (ACF) convened by the Arctic Regional Climate Centre Network (ArcRCC-Network) under the auspices of the World Meteorological Organization (WMO) provides consensus climate outlook statements in May prior to summer thawing and sea-ice break-up, and in October before the winter freezing and the return of sea-ice. The role of the ArcRCC-Network is to foster collaborative regional climate services amongst Arctic meteorological and ice services to synthesize observations, historical trends, forecast models and fill gaps with regional expertise to produce consensus climate statements. These statements include a review of the major climate features of the previous season, and outlooks for the upcoming season for temperature, precipitation and sea-ice. The elements of the consensus statements are presented and discussed at the Arctic Climate Forum (ACF) sessions with both providers and users of climate information in the Arctic twice a year in May and October, the later typically held online.

  • The Ross Sea: a Valuable Reference Area to Assess the Effects of Climate Change
    IP (number) Agenda Item: CEP 7e, ATCM 13 Presented by: ASOC Original: English The Ross Sea: A Valuable Reference Area to Assess the Effects of Climate Change 1 IP (number) Summary International Panel on Climate Change models predict that the Ross Sea will be the last portion of the Southern Ocean with sea ice year round. Currently, the Ross Sea ecosystem is considered to be relatively little affected by direct human-related impacts other than the past exploitation of marine mammals along its slope and the recent exploratory Antarctic toothfish fishery. The indirect human impacts of CO2 pollution on melting ice and ocean acidification have yet to be felt. The Ross Sea - with its several very long biotic and hydrographic data sets - constitutes an important reference area to gauge the ecosystem effects of climate change and distinguish those effects from the effects of current fisheries, tourism, and historic overexploitation and recovery or lack of recovery of some seal, whale, and fish populations elsewhere. This, in conjunction with a range of other scientific and biological reasons that has been laid out in prior ASOC papers, underpins why the Ross Sea should be included as a key component in the network of marine protected areas currently being considered for the Southern Ocean by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). 1. Introduction Over the past few years, ASOC has put forward a number of papers making the ‘science case’ for supporting full protection of the Ross Sea slope and shelf,1 in the context of establishing an important component of a representative network of MPAs in the Southern Ocean.2 This paper focuses on the climate reference zone potential of the Ross Sea.

The interplay between regional grounding 1234567890():,; line change and potentially diverse ice flow behaviour of contributing catchments is relevant to an ice sheet’s stability and resilience to change. At the last glacial maximum, marine-based ice streams in the western Ross Sea were fed by numerous catchments draining the East Antarctic Ice Sheet. Here we present geomorphological and acoustic stratigraphic evidence of ice sheet reorganisation in the South Victoria Land (SVL) sector of the western Ross Sea. The opening of a grounding line embayment unzipped ice sheet sub-sectors, enabled an ice flow direction change and triggered enhanced flow from SVL outlet glaciers. These relatively small catchments behaved independently of regional grounding line retreat, instead driving an ice sheet readvance that delivered a significant volume of ice to the ocean and was sustained for centuries. 1 Department of Geological Sciences, Stockholm University, Stockholm 10691, Sweden. 2 Department of Earth, Environmental and Planetary Sciences, Rice University, Houston, TX 77005, USA. 3 Department of Environmental Sciences, University of Virginia, Charlottesville, VA 22904, USA. 4 Department
