Sea-ice switches and abrupt climate change.
We propose that past abrupt climate changes were probably a result of rapid and extensive variations in sea-ice cover. We explain why this seems a perhaps more likely explanation than a purely thermohaline circulation mechanism. We emphasize that because of the significant influence of sea ice on the climate system, it seems that high priority should be given to developing ways for reconstructi...
متن کاملClimate Change, Health, and Vulnerability in Canadian Northern Aboriginal Communities
BACKGROUND Canada has recognized that Aboriginal and northern communities in the country face unique challenges and that there is a need to expand the assessment of vulnerabilities to climate change to include these communities. Evidence suggests that Canada's North is already experiencing significant changes in its climate--changes that are having negative impacts on the lives of Aboriginal pe...
متن کاملNorthern Hemisphere Ice-Sheet Influences on Global Climate Change
Large ice sheets actively interact with the rest of the climate system by amplifying, pacing, and potentially driving global climate change over several time scales. Direct and indirect influences of ice sheets on climate cause changes in ocean surface temperatures, ocean circulation, continental water balance, vegetation, and landsurface albedo, which in turn cause additional feedbacks in the ...
متن کاملArctic sea ice trends and narwhal vulnerability
Conservation measures related to global climate change require that species vulnerability be incorporated into population risk models, especially for those that are highly susceptible to rapid or extreme changes due to specialized adaptation. In the case of Arctic cetaceans, effects of climate change on habitat and prey availability have been subject to intense speculation. Climate perturbation...
