Climate of the Arctic - Wikipedia

The climate of the Arctic is characterized by long, cold winters and short, cool summers There is a large amount of variability in climate across the Arctic, but all regions experience extremes of solar radiation in both summer and winterCentral Arctic surface ocean environment during the past ,Stable oxygen and carbon isotope and sedimentological‐paleontological investigations supported by accelerator mass spectrometry 14 C datings were carried out on cores from north of 85°N in the eastern central Arctic OceanHow did that get there? Plastic chunks on Arctic ice show ,Plastic chunks on Arctic ice show how far pollution has spread Discovery by UK scientists prompts fear that melting ice will allow more plastic to be released into the central Arctic Ocean
