This loss of ice globally is even causing the Earth’s crust to warp.
A side effect of this situation is the artefacts and scientific discoveries unveiled by the receding ice.
First World War cave shelter and trove of artefacts
A total of 300 objects were found as a result of the melt, with straw mattresses, coins, helmets, ammunition, bottles, tins, and even newspapers.
Viruses over 15,000 years old found in Tibet
The viruses, which are unlike those known to science, were found in ice samples drilled from the Guliya ice cap in the Tibetan Plateau, in western China.
The novel viruses are not believed to be harmful to humans, according to the scientists who hope that the viruses can help them understand more about virus evolution and climate change.
Mammoths and rhinoceros bones in Russia
An investigation by Sky News into the environmental damage caused by the thawing of this region’s vast carbon stores found parts of mammoth tusk as well as fragments of woolly rhinoceros bone.
The animals once roamed the Arctic grasslands before becoming extinct: rhinos around 14,000 to 15,000 years ago and mammoths about 10,500 years ago, at the end of the last ice age.
The bone and tusk fragments were found in Duvanny Yar, near Chersky in the Siberian Arctic – home to international research stations where scientists congregate to study the impact of the retreating ice.
Radioactive waste in Arctic
The rapid thaw of Arctic permafrost could release radioactive waste from Cold War nuclear submarines, antibiotic-resistant bacteria, and new viruses, a report has found.
Between 1955 and 1990, the Soviet Union conducted 130 nuclear weapons tests on the Novaya Zemlya archipelago off the coast of northwest Russia. The tests released around 265 megatons of nuclear energy and more than 100 decommissioned nuclear submarines were scuttled in the nearby Kara and Barents seas.
The United States’ Camp Century nuclear-powered under-ice research facility in Greenland also produced “considerable nuclear and diesel waste”.
Meanwhile, deep permafrost of more than three metres is one of the few environments on Earth that has not been exposed to modern antibiotics.
More than 100 diverse microorganisms in Siberian deep permafrost have been found to be antibiotic-resistant, and as permafrost thaws, there is potential for these bacteria to mix with meltwater and create new antibiotic-resistant strains of existing bacteria.
This article was amended on 4 January 2022. It previously stated incorrectly that frozen bacteria could mix with meltwater and ‘create new antibiotic-resistant strains of existing viruses’, but it should have said of ‘new antibiotic-resistant strains of existing bacteria’.
