Scientists studying the northern Bering Sea say they are seeing changes in ocean conditions that have been predicted by climate models, but not before 2050.
In the Bering Sea last winter there was a record amount of ice. Oceanographer Phyllis Stabino says it's too early to attribute those changes to climate change and she expected an increase this winter.
Instead, warm winds cleared most of the sea ice in February.
Oceanographer Seth Danielson says the changes are causing biological effects.
Because of this, commercially valuable fish have moved further north. Seabird experts say the mass die-off of these birds may be linked to the state of the ocean.
