The presence of the Arctic sea ice cover has a profound influence on the polar climate in the Northern Hemisphere (e.g., see Walsh, 1983; Parkinson et al., 1987). First, the ice cover reflects a large fraction of the incident solar radiation because the ice has a larger albedo than ...
The main characteristics of sea ice to affect the other components of the climate system are (a) prevention or reduction in the exchange of heat, momentum, water vapour, and other materia between the atmosphere and ocean and (b) much higher surface albedo than that of the open ocean. Hence...
BEIJING, Oct. 1 (Xinhua) -- An international group led by Chinese scientists has revealed that the Arctic Ocean is seeing much faster acidification than elsewhere in the world's open oceans due to the sea ice melt there. The study published on Friday in the journal Science shows that the ...
We document that even under such warmer climate conditions, sea ice existed in the central Arctic Ocean during summer, whereas sea ice was significantly reduced along the Barents Sea continental margin influenced by Atlantic Water inflow. Our proxy reconstruction of the last interglacial sea ice ...
A consensus among climate change prediction scenarios using coupled ocean-climate general circulation models (GCMs) is enhanced warming in the Arctic. This suggests that changes in the Arctic sea ice cover may provide early indications of global warming. Observational evidence of substantial changes in...

There are two main reasons. The Arctic is an ocean surrounded by land, and human activities on the surrounding land have a direct impact on it. Also, when sea ice, snow, glaciers and permafrost melt, darker land or ocean surfaces can absorb more energy from the sun, causing a...
