There’s been a lot of speculations regarding the melting of arctic ice due to global warming, which spells disaster for all living beings, so scientists have decided to conduct some serios investigations and learn if there’s any real danger.

Sea-lions will play a serious part in the gathering of important data about the status of the ice, water temperature and climate change.
