<P> The sea ice at the North Pole is typically around 2 to 3 m (6 ft 7 in to 9 ft 10 in) thick, although ice thickness, its spatial extent, and the fraction of open water within the ice pack can very rapidly and profoundly in response to weather and climate . Studies have shown that the average ice thickness has decreased in recent years . It is likely that global warming has contributed to this, but it is not possible to attribute the recent abrupt decrease in thickness entirely to the observed warming in the Arctic . Reports have also predicted that within a few decades the Arctic Ocean will be entirely free of ice in the summer . This may have significant commercial implications; see "Territorial Claims," below . </P> <P> The retreat of the Arctic sea ice will accelerate global warming, as less ice cover reflects less solar radiation, and may have serious climate implications by contributing to Arctic cyclone generation . </P> <Table> <Tr> <Th_colspan="14"> (hide) Climate data for Greenlandic Weather Station (eleven year average observations) </Th> </Tr> <Tr> <Th> Month </Th> <Th> Jan </Th> <Th> Feb </Th> <Th> Mar </Th> <Th> Apr </Th> <Th> May </Th> <Th> Jun </Th> <Th> Jul </Th> <Th> Aug </Th> <Th> Sep </Th> <Th> Oct </Th> <Th> Nov </Th> <Th> Dec </Th> <Th> Year </Th> </Tr> <Tr> <Th> Record high ° C (° F) </Th> <Td> − 13 (9) </Td> <Td> − 14 (7) </Td> <Td> − 11 (12) </Td> <Td> − 6 (21) </Td> <Td> (37) </Td> <Td> 10 (50) </Td> <Td> 13 (55) </Td> <Td> 12 (54) </Td> <Td> 7 (45) </Td> <Td> − 2 (28) </Td> <Td> 0.6 (33.1) </Td> <Td> 0.7 (33.3) </Td> <Td> 13 (55) </Td> </Tr> <Tr> <Th> Average high ° C (° F) </Th> <Td> − 29 (− 20) </Td> <Td> − 31 (− 24) </Td> <Td> − 30 (− 22) </Td> <Td> − 22 (− 8) </Td> <Td> − 9 (16) </Td> <Td> 0 (32) </Td> <Td> (36) </Td> <Td> (34) </Td> <Td> − 7 (19) </Td> <Td> − 18 (0) </Td> <Td> − 25 (− 13) </Td> <Td> − 26 (− 15) </Td> <Td> − 16 (3) </Td> </Tr> <Tr> <Th> Daily mean ° C (° F) </Th> <Td> − 31 (− 24) </Td> <Td> − 32 (− 26) </Td> <Td> − 31 (− 24) </Td> <Td> − 23 (− 9) </Td> <Td> − 11 (12) </Td> <Td> − 1 (30) </Td> <Td> (34) </Td> <Td> 0 (32) </Td> <Td> − 9 (16) </Td> <Td> − 20 (− 4) </Td> <Td> − 27 (− 17) </Td> <Td> − 28 (− 18) </Td> <Td> − 18 (0) </Td> </Tr> <Tr> <Th> Average low ° C (° F) </Th> <Td> − 33 (− 27) </Td> <Td> − 35 (− 31) </Td> <Td> − 34 (− 29) </Td> <Td> − 26 (− 15) </Td> <Td> − 12 (10) </Td> <Td> − 2 (28) </Td> <Td> 0 (32) </Td> <Td> − 1 (30) </Td> <Td> − 11 (12) </Td> <Td> − 22 (− 8) </Td> <Td> − 30 (− 22) </Td> <Td> − 31 (− 24) </Td> <Td> − 20 (− 4) </Td> </Tr> <Tr> <Th> Record low ° C (° F) </Th> <Td> − 47 (− 53) </Td> <Td> − 50 (− 58) </Td> <Td> − 50 (− 58) </Td> <Td> − 41 (− 42) </Td> <Td> − 24 (− 11) </Td> <Td> − 12 (10) </Td> <Td> − 2 (28) </Td> <Td> − 12 (10) </Td> <Td> − 31 (− 24) </Td> <Td> − 41 (− 42) </Td> <Td> − 41 (− 42) </Td> <Td> − 47 (− 53) </Td> <Td> − 50 (− 58) </Td> </Tr> <Tr> <Th> Average relative humidity (%) </Th> <Td> 83.5 </Td> <Td> 83.0 </Td> <Td> 83.0 </Td> <Td> 85.0 </Td> <Td> 87.5 </Td> <Td> 90.0 </Td> <Td> 90.0 </Td> <Td> 89.5 </Td> <Td> 88.0 </Td> <Td> 84.5 </Td> <Td> 83.0 </Td> <Td> 83.0 </Td> <Td> 85.8 </Td> </Tr> <Tr> <Td_colspan="14"> Source: Weatherbase </Td> </Tr> </Table> <Tr> <Th_colspan="14"> (hide) Climate data for Greenlandic Weather Station (eleven year average observations) </Th> </Tr>
