More evidence has emerged suggesting there is more sea ice in the Arctic today than nearly any time in the last 8000 years.<\/strong><\/h4>\n\n\n\n

According to a new study<\/a><\/strong>, biomarker evidence suggests the Barents Sea (Arctic) was seasonally \u201cice free\u201d from ~8000 to ~2100 years ago, or back when the CO2 concentration was said to be about 265 ppm.<\/p>\n\n\n\n

Since that warmer Arctic period, the climate cooled and sea ice extent expanded.<\/p>\n\n\n\n

For the last 2100 years sea there has been year-round sea ice in this region . Today the minimum sea ice coverage is in August and September, whereas the maximum ice coverage is in March\/April.<\/p>\n\n\n\n

The modern period (1988-2007) has among the highest sea ice levels of the Holocene, with ~80% coverage in spring (Koseoglu, 2019<\/strong><\/a>).<\/p>\n\n\n\n
