Open Ended

Because of global warming it will be a very hot summer in the Arctic. The sun will shine for 24 hours a day.

As the Arctic gets warmer the ice caps will melt. As the ice caps to melt the ocean will rise and get warmer.

Polar bears need the ice caps as the white ice helps them to camouflage and hunt.

As the oceans rise they get warmer, this causes toxic algae bloom and fish to die.

Predict what would happen to the krill population if global warming continues to affect the arctic.
