It's been unseasonably warm in many parts of the country this winter, but nothing compared to the Arctic. Temperatures normally hover around four degrees below zero, but have been climbing much higher.

Laura Geggel, Senior Writer at Live Science, explains why these high temperatures are causing concern. Heat waves in the arctic aren't a new phenomenon, but normally they happen once every 10 years. The last heat wave in the arctic was just two years ago.

Geggel also discusses a German company's plan to establish a 4G mobile coverage on the moon. The network will reportedly be set up in 2019.
