Climate indicators for Sea Ice

Climate indicators for Sea Ice Time series of sea ice extent in the Arctic. Data available through the Copernicus Marine Environment Monitoring Service (CMEMS)

$Sea Ice Extent (SIE) is defined as the area covered by sea ice, that is the area of ocean having more than 15% Sea Ice Concentration (SIC). Sea Ice Concentration is the fractional coverage of an ocean area covered with sea ice. All Northern Hemisphere sea ice is included, except for lake or river ice. The SIC data are computed from passive microwave satellite data.$ Arctic Monthly Mean Sea Ice Extent Sea Ice Extent (SIE) is defined as the area covered by sea ice, that is the area of ocean having more than 15% Sea Ice Concentration (SIC).

The Arctic Environment

The Arctic Environment This European Environment Agency (EEA) report contributes to the growing international discourse on the Arctic region. It is both timely and important, since it examines the increasingly rapid changes that are taking place in the Arctic from a European perspective. It considers the national, regional and global challenges and opportunities that are emerging as a result

Climate change, impacts and vulnerability in Europe 2016

Climate change, impacts and vulnerability in Europe 2016 This report is an indicator-based assessment of past and projected climate change and its impacts on ecosystems and society. It also looks at society’s vulnerability to these impacts and at the development of adaptation policies and the underlying knowledge base. This is the fourth ‘Climate change, impacts and vulnerability in Europe’ report, which is published every four years. This edition aims to support the implementation and review process of the 2013 EU Adaptation Strategy, which is foreseen for 2018, and the development of national and transnational adaptation strategies and plans.
