A Spatial Evaluation of Arctic Sea Ice and Regional Limitations in CMIP6 Historical Simulations
1AUGUST 2021 W A T T S E T A L . 6399 A Spatial Evaluation of Arctic Sea Ice and Regional Limitations in CMIP6 Historical Simulations a a a a MATTHEW WATTS, WIESLAW MASLOWSKI, YOUNJOO J. LEE, JACLYN CLEMENT KINNEY, AND b ROBERT OSINSKI a Department of Oceanography, Naval Postgraduate School, Monterey, California b Institute of Oceanology of Polish Academy of Sciences, Sopot, Poland (Manuscript received 29 June 2020, in final form 28 April 2021) ABSTRACT: The Arctic sea ice response to a warming climate is assessed in a subset of models participating in phase 6 of the Coupled Model Intercomparison Project (CMIP6), using several metrics in comparison with satellite observations and results from the Pan-Arctic Ice Ocean Modeling and Assimilation System and the Regional Arctic System Model. Our study examines the historical representation of sea ice extent, volume, and thickness using spatial analysis metrics, such as the integrated ice edge error, Brier score, and spatial probability score. We find that the CMIP6 multimodel mean captures the mean annual cycle and 1979–2014 sea ice trends remarkably well. However, individual models experience a wide range of uncertainty in the spatial distribution of sea ice when compared against satellite measurements and reanalysis data. Our metrics expose common and individual regional model biases, which sea ice temporal analyses alone do not capture. We identify large ice edge and ice thickness errors in Arctic subregions, implying possible model specific limitations in or lack of representation of some key physical processes. We postulate that many of them could be related to the oceanic forcing, especially in the marginal and shelf seas, where seasonal sea ice changes are not adequately simulated. -
Some Aspects of the Thermal Energy Exchange on the South Polar Snow Field and Arctic Ice Pack'
MAY 1961 MONTHLY WEATHER REVIEW 173 SOME ASPECTS OF THE THERMAL ENERGY EXCHANGE ON THE SOUTH POLAR SNOW FIELD AND ARCTIC ICE PACK' KIRBY J. HANSON Po!ar Meteorology Research Project, US. Weather Bureau, Washington, D.C. [Manuscript received September 13, 1960; revised February 21, 1961 ] ABSTRACT Solar and terrestrial radiation measurements that were obtained at Amundsen-Scot>t (South Pole) Station and on Ice lsland (Bravo) T-3 are presented for representative summer and winter months. Of the South Polar net radiation loss during April 1958, approximately20 percent of the energy came from the snow and80 percent from the air. The actual atmospheric cooling rate during that period was only about lj6 of the suggested radiative cooling rate. The annual net radiation at various places in Antarctica is presented. During 1058, the South Polar atmos- phere transmitted about 73 percent of the annual extraterrestrial radiation, while at T-3 the Arctic atmosphere transmitted about 56 percent. The albedo of melting sea ice is discussed. Measurements on T-3 during July 1958 indicate that the net radiation is positive on both clear and overcast days but greatest on overcast days. Refreezing of the surface with clear skies, as observed by Untersteiner and Badglep, is discussed. 1.

MARCH 1999 VAVRUS 873 The Response of the Coupled Arctic Sea Ice±Atmosphere System to Orbital Forcing and Ice Motion at 6 kyr and 115 kyr BP STEPHEN J. VAVRUS Center for Climatic Research, Institute for Environmental Studies, University of WisconsinÐMadison, Madison, Wisconsin (Manuscript received 2 February 1998, in ®nal form 11 May 1998) ABSTRACT A coupled atmosphere±mixed layer ocean GCM (GENESIS2) is forced with altered orbital boundary conditions for paleoclimates warmer than modern (6 kyr BP) and colder than modern (115 kyr BP) in the high-latitude Northern Hemisphere. A pair of experiments is run for each paleoclimate, one with sea-ice dynamics and one without, to determine the climatic effect of ice motion and to estimate the climatic changes at these times. At 6 kyr BP the central Arctic ice pack thins by about 0.5 m and the atmosphere warms by 0.7 K in the experiment with dynamic ice. At 115 kyr BP the central Arctic sea ice in the dynamical version thickens by 2±3 m, accompanied bya2Kcooling. The magnitude of these mean-annual simulated changes is smaller than that implied by paleoenvironmental evidence, suggesting that changes in other earth system components are needed to produce realistic simulations. Contrary to previous simulations without atmospheric feedbacks, the sign of the dynamic sea-ice feedback is complicated and depends on the region, the climatic variable, and the sign of the forcing perturbation. Within the central Arctic, sea-ice motion signi®cantly reduces the amount of ice thickening at 115 kyr BP and thinning at 6 kyr BP, thus serving as a strong negative feedback in both pairs of simulations. -
Educator Guide
E DUCATOR GUIDE This guide, and its contents, are Copyrighted and are the sole Intellectual Property of Science North. E DUCATOR GUIDE The Arctic has always been a place of mystery, myth and fascination. The Inuit and their predecessors adapted and thrived for thousands of years in what is arguably the harshest environment on earth. Today, the Arctic is the focus of intense research. Instead of seeking to conquer the north, scientist pioneers are searching for answers to some troubling questions about the impacts of human activities around the world on this fragile and largely uninhabited frontier. The giant screen film, Wonders of the Arctic, centers on our ongoing mission to explore and come to terms with the Arctic, and the compelling stories of our many forays into this captivating place will be interwoven to create a unifying message about the state of the Arctic today. Underlying all these tales is the crucial role that ice plays in the northern environment and the changes that are quickly overtaking the people and animals who have adapted to this land of ice and snow. This Education Guide to the Wonders of the Arctic film is a tool for educators to explore the many fascinating aspects of the Arctic. This guide provides background information on Arctic geography, wildlife and the ice, descriptions of participatory activities, as well as references and other resources. The guide may be used to prepare the students for the film, as a follow up to the viewing, or to simply stimulate exploration of themes not covered within the film. -
The North Caucasus Region As a Blind Spot in the “European Green Deal”: Energy Supply Security and Energy Superpower Russia
energies Article The North Caucasus Region as a Blind Spot in the “European Green Deal”: Energy Supply Security and Energy Superpower Russia José Antonio Peña-Ramos 1,* , Philipp Bagus 2 and Dmitri Amirov-Belova 3 1 Faculty of Social Sciences and Humanities, Universidad Autónoma de Chile, Providencia 7500912, Chile 2 Department of Applied Economics I and History of Economic Institutions (and Moral Philosophy), Rey Juan Carlos University, 28032 Madrid, Spain; [email protected] 3 Postgraduate Studies Centre, Pablo de Olavide University, 41013 Sevilla, Spain; [email protected] * Correspondence: [email protected]; Tel.: +34-657219669 Abstract: The “European Green Deal” has ambitious aims, such as net-zero greenhouse gas emissions by 2050. While the European Union aims to make its energies greener, Russia pursues power-goals based on its status as a geo-energy superpower. A successful “European Green Deal” would have the up-to-now underestimated geopolitical advantage of making the European Union less dependent on Russian hydrocarbons. In this article, we illustrate Russian power-politics and its geopolitical implications by analyzing the illustrative case of the North Caucasus, which has been traditionally a strategic region for Russia. The present article describes and analyses the impact of Russian intervention in the North Caucasian secessionist conflict since 1991 and its importance in terms of natural resources, especially hydrocarbons. The geopolitical power secured by Russia in the North Caucasian conflict has important implications for European Union’s energy supply security and could be regarded as a strong argument in favor of the “European Green Deal”.

Mare Nostrum Strategy: Russian Military Activity in the Black Sea
SPECIAL REPORT 03/21/2019 MARE NOSTRUM STRATEGY: RUSSIAN MILITARY ACTIVITY IN THE BLACK SEA Warsaw Institute MARE NOSTRUM STRATEGY: RUSSIAN MILITARY ACTIVITY IN THE BLACK SEA SOURCE: MIL.RU l Owing to its geographic location, Russia’s prerequisite to acquire and maintain the status of a superpower has long been to seize and retain control over two maritime „windows to the world.” This strategy was first mapped out by Peter the Great and led to multiple wars in the Baltic and Black Seas. l Russia has in the past focused on intensifying its activities in the south, as exemplified by the conflict with Ukraine and Moscow’s armed intervention in the Syrian civil war. Symbolically, this is illustrated by making the Black Sea city of Sochi Russia’s „summer capital” and a place where Vladimir Putin hosts world leaders and Kremlin officials. l The Black Sea is to become a platform from where Russia is able to exert influence on neighboring regions, including the Middle East, the Balkans and the Mediterranean countries. The Kremlin’s accom- plishments in the Black Sea region and friendly ties with the Turkish authorities successfully obstructed shipping Caspian hydrocarbon supplies to Europe. l Thanks to the annexation of Crimea from Ukraine in 2014 and increased combat capabilities in the immediate vicinity of the peninsula, Russia finally managed to regain dominance across the Black Sea it had lost in 1991. For Russia, it is vital to exert full control over Crimea as it will permit the Kremlin to hold Kiev in check while extending field reconnaissance activities and firing capabilities to the vast area of the Black Sea. -
