If global greenhouse gas emissions continue to rise at the current rate, the Arctic could lose all of its sea ice by 2030. Reducing emissions could delay this event until at most 2050. This estimate is a decade earlier than previously predicted by the Intergovernmental Panel on Climate Change (IPCC): An ice-free Arctic by the 2040s. A possible ice-free Arctic in 2030-2050 was proposed by Professor Seung-Ki Min and Research Professor Yeon-Hee Kim from the Division of Environmental Science and Engineering at Pohang University of Science and regardless of humanity's efforts to reduce greenhouse gas emissions. Technology (POSTECH) and a joint team of researchers from Environment Climate Change Canada and Universität Hamburg, Germany. The research was published in the international journal Nature Communications .

The term global warming has become a concept since it was first used by a climate scientist from NASA in 1988. The Earth has seen a rapid decline in Arctic sea ice extent as its temperature has increased over the past few decades. This reduction in Arctic sea ice has triggered an acceleration of Arctic warming, which is thought to contribute to the increased frequency of extreme weather events in mid-latitude regions.
