Satellite observations have been instrumental in monitoring Arctic sea ice extent and thickness, and its changes over time.
From space sensors, can track seasonal and long-term trends. Arctic ice cover is shown to shrinking at an alarming rate, leading to concerns about its impact on the regional and global climate system.
By continuously monitoring Arctic sea ice from space, researchers can better understand the dynamics of this critical component of our planet's climate system and make informed decisions to address the challenges posed by its decline. This data-driven graphic represents the area of arctic sea ice observed by satellites in 1980 compared to 2016.
The Little Picture aims to highlight the decline of sea ice in the Arctic between 1980 and 2020. There are already various graphs and visualisations that impressively show the decline of the ice (in volume and also as area). The idea behind this CLIP is the spatial comparison based on a visual trick: the extent of the ice is shifted from the pole to central Europe. This makes the area of the retreat even clearer.
The Little Picture uses the following datasets:

The big picture
The European Space Agency (ESA), the European Centre for Medium-Range Weather Forecasts (ECMWF), and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) work closely together to measure, process & make space-derived information about the climate available.
The mission of the Climate Change Initiative (CCI) is to realise the full potential of the long-term global Earth Observation archives that the European Space Agency (ESA), together with its Member states, has established over the past 40 years, as a significant and timely contribution to the climate databases required by the United Nations Framework Convention on Climate Change. The ESA Climate Office provides a free & open CCI data facility bringing together ECV data from across its twenty-seven climate science projects, including a CCI Data Standards and a CCI Toolbox.
The Copernicus Climate Change Service (C3S) supports society by providing freely available authoritative information about the past, present and future climate in Europe and the rest of the World. C3S is one of the six thematic information services provided by the Copernicus Earth Observation Programme of the European Union, and has been entrusted by the European Commission to the European Centre for Medium-Range Weather Forecasts (ECMWF). One of the core components of C3S includes the Climate Data Store (CDS). This is a one-stop shop for climate information. It provides free and easy access to a wide range of climate datasets via a searchable catalogue. A freely available online toolbox allows users to build workflows and applications suited to their needs.
EUMETSAT operates missions both to provide weather and climate data for its member states, and as an entrusted entity under the Copernicus programme. Several missions are operated collaboratively with ESA, providing complimentary expertise and data processing, to process and distribute land, marine, and atmosphere relevant products for users. Data from EUMETSAT operated missions is frequently available in near-real-time, facilitating rapid monitoring and forecasting. Via EUMETCast, the EUMETSAT Data Services, or WEkEO, users can access data in ways that suit their needs. The data is used by the EUMETSAT satellite applications facilities, as well as across the various Copernicus Services.
