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 ...
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...
climate changeArctic OceanCMIP2 simulations[1] In this work, we analyze the two-dimensional distribution of mean and intermodel spread of Arctic sea ice and climate change at the time of CO2 doubling and their connection using the simulations from the second phase of the Coupled Model ...
They found that due to climate change and subsequent sea ice retreat, a larger area of seawater that was initially covered by ice has been exposed to the atmosphere, which promotes the rapid uptake of atmospheric CO2, thus leading to drastic ocean acidification and lowering the oceanic buffering ...
Here's yet another new and great video by Peter Sinclair from the ClimateCrocks blog for the Yale Forum on Climate Change and the Media: It bears repeating... This video should get at least 50 million views. I think it will one day.
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...
The climate change in the Arctic has been at least twice as fast as the global average (Blunden and Arndt2012). One of the most dramatic indicators of the Arctic warming has been the decline in the sea ice cover. This has been manifested as a decrease in the ice extent, ice thickness,...
In general, the Arctic sea ice reaches its minimum extent in September each year, and global climate change has brought significant changes to the sea ice cover, with nearly 50 percent of losses since 1979, according to Liu. The Arctic sea ice cover shrank to 3.41 million square kilometers ...
The Arctic will soon be free from ice, experts say. The change is bound to take place, but the global warming and climate change are changing the earth's landscape (地形) rapidly,causing panic worldwide. Experts say that the Arctic sea ice is melting (融化) quite faster than expected and...
Arctic climate change has the potential to affect access to semi-permanent trails on land, water and sea ice, which are the main forms of transport for communities in many circumpolar regions. Focusing on Inuit Nunangat (the Inuit homeland in northern Canada), trail access models were developed...
