Sea Ice
	q  One major climate effect of sea ice is to seal off the underlying ocean from interaction with the atmosphere. q  Without an sea ice cover, high-latitude oceans transfers large amount of heat to the atmosphere, especially in winter. q  With an sea ice cover, the heat flux into the atmosphere is stopped. In addition, the ice surface absorbs little incoming solar radiation. Winter air temperature can cool 30°C or more near a sea-ice cover.
