Environmental engineer Gil Bohrer discusses how long-term, large-scale tracking data can shed light on the unexpected ways animals are responding to changes in the Arctic.

Knock-on effects of melting sea ice in the Arctic may be to blame for a spate of gray whale deaths along their migration route from Mexico to Alaska.

For the past two years, the charismatic marine mammals have washed up on Pacific shores in record numbers. Scientists investigating the strandings suspect warming waters and melting sea ice are partly to blame.

Satellite images of penguin poop reveal eight entirely new colonies and confirm the existence of another three first reported in the 1960s.

The possibly record-breaking temps follow the warmest winter on record in the region.

The rate of population decline is outpacing the ability of the bees to find a new habitat.

The movements of water within the ocean basins has been increasing in speed over the last 20 years, a new study shows, conflicting with prior models of climate change.
