CLEAN : Arctic floating ice cover at second lowest level on record: expert

The video discusses the alarming changes in the Arctic, highlighting the second lowest Arctic sea ice extent on record in 2020, following the lowest in 2012. It emphasizes the reduction in ice thickness and volume, with multiyear ice being replaced by single-year ice that melts and reforms annually. The Arctic is warming over twice as fast as the global average, with 2020 being particularly notable for a severe heatwave in Siberia, where temperatures exceeded 38°C. These changes are attributed to climate change, indicating a trend towards an ice-free Arctic Ocean during summer.
