The Antarctic is responding less rapidly to climate change than the Arctic. In its sixth assessment report, the Intergovernmental Panel on Climate Change (IPCC) of the United Nations states that human influence is very likely the main driver of the global retreat of Arctic sea ice during the last 40 years. The area of late summer Arctic sea ice is now smaller than at any time in at least the past 1,000 years.

In fact, the current Arctic sea ice area is at its lowest level since at least 1850. In these regions, temperatures rose about 2☌ in the Arctic and between 1.0 and 1.5☌ in the Antarctic.Īmong other impacts, this warming resulted in a decrease of the Arctic sea ice area and ice thickness in both summer and winter, with sea ice becoming younger, thinner and more dynamic. Our planet's polar regions, however, are warming faster than other places ( IPCC, 2021 ). The planets average temperature has risen a little more than 1☌ since the start of the industrial era. The effects of climate change are not the same in all parts of the world.
