<strong>EUMETSAT</strong> ANNUAL REPORT <strong>2022</strong><br />

Case study<br />

Climate<br />

change in the<br />

European<br />

context<br />

The annual European State<br />

of the Climate <strong>Report</strong> was<br />

published on 22 April <strong>2022</strong>.<br />

<strong>EUMETSAT</strong> data, products, and<br />

services made a significant<br />

contribution to the report.<br />

Compiled by the Copernicus Climate Change Service,<br />

implemented by the European Centre for Medium-<br />

Range Weather Forecasts on behalf of the European<br />

Commission, the report detailed a year of contrasts.<br />

Spring was cooler than average but the summer<br />

was the hottest on record, with temperatures close<br />

to 1°C above the 1991-2020 average.<br />

The report also detailed extreme events such as<br />

devastating floods in western Europe in July, which<br />

killed more than 200 people and caused about €15<br />

billion damage, and summer wildfires that burned<br />

more than 800,000 hectares across southern Europe.<br />

The report stated that extreme weather events<br />

experienced in Europe in 2021 are made more likely by<br />

climate change, and stressed the urgent need to act.<br />

Sea ice extent<br />

In the Arctic Ocean, the extent and thickness of<br />

sea ice has fallen dramatically over the past four<br />

decades. The melting ice is strongly connected to<br />

heating in the region over the same time. Average<br />

summer sea ice concentration decreased by 11.8%<br />

each decade relative to the 1981-2010 average.<br />

A smaller, yet equally pronounced, decline also<br />

occurred during winter. Arctic ice thickness is also<br />

reported to be plummeting by an average of around<br />

13% per decade.<br />

<strong>EUMETSAT</strong>’s Ocean and Sea Ice Satellite<br />

Application Facility (OSI SAF) uses satellite imagery<br />

to track changes and movement of global sea ice<br />

on a daily basis.<br />

The data analysed by the OSI SAF can be used to<br />

provide some of the most direct visualisations of<br />

climate change, with graphs mapping year-onyear<br />

variations.<br />

“Satellite observations are the foundation for most<br />

of our knowledge about the evolution of the global<br />

sea ice cover,” Dr Jörg Schulz, <strong>EUMETSAT</strong>’s leading<br />

climate scientist, said. “OSI SAF products provide<br />

essential evidence for understanding how climate<br />

change is playing out in polar regions.<br />

Sunshine duration<br />

As solar radiation passes through the atmosphere,<br />

it is scattered, reflected, and absorbed by air<br />

molecules, small airborne particles, water droplets,<br />

and ice crystals.<br />

Longer-term variations in surface solar radiation<br />

are likely a result of human activities, with aerosol<br />

pollutants very probably major drivers. In Europe,<br />

annual sunshine duration shows a clear upward<br />

trend over the past four decades.<br />
