Research indicates that climate change is driving significant environmental shifts, particularly regarding polar ice loss and ocean warming. Data from the IMBIE international team shows that Greenland and Antarctica have lost 11.3 trillion tonnes of ice since the 1970s, contributing 3.1 centimeters to global sea level rise.

Further observations from the Copernicus Marine Service highlight rapid transformations in polar oceans. Arctic surface temperatures rose by 4.2 degrees Celsius between 1982 and 2024, with specific areas like Russia’s Kara Sea seeing increases of 6.7 degrees Celsius over 40 years. This warming has resulted in a 17% reduction in sea ice surface area over 42 years.

The consequences of these changes include increased coastal vulnerability to erosion and rising sea levels, with an estimated 60% of Arctic coastal infrastructure at risk. Additionally, the intensification of storms due to rising temperatures is linked to greater economic losses, with increased risks of stronger tropical cyclones and frequent extratropical cyclones in northern Europe.
