Atmosphere    Sea Ice    Greenland    Biology    Ocean    Land Warming and mixed signals

Collectively, the observations indicate that the overall warming of the Arctic system continued in 2007. There are some elements that are stabilizing or returning to climatological norms. These mixed tendencies illustrate the sensitivity and complexity of the Arctic System.

	Atmosphere Hot spot shifts toward Europe			Ocean North Pole Temperatures at depth returning to 1990s values
	Sea Ice Summer extent at record minimum			Greenland Recent warm temperatures associated with net ice loss
	Biology • Increasing tundra shrub cover and variable treeline advance • Up to 80% declines in some caribou herds, while goose populations double			Land Increase in permafrost temperatures is slowing down
