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.

The U.S. Faces a Massive Plastic Waste Problem — What is Congress Doing About It?
The U.S. has a million-ton problem: each year, hundreds of pounds of plastic waste are produced per person, and that leads to close to 2 million tons of that waste leaking into the environment. Eight million tons end up in the ocean, where it hinders marine life, damages ecosystems, and impacts industry. But in recent years, Congress has introduced measures including the Save our Seas act to try to mitigate the issue and turn our plastic problem around. Sen. Chris Murphy (D-CT) joins Cheddar Climate to discuss why the U.S. is the top global polluter of plastic, what Congress is doing to try to fix the issue, and more.

Why Commercial Planes Are Shrinking
Earlier this year, JetBlue flew its inaugural flight into the United Kingdom. It was a game changer — not only did the airline enter the transatlantic market, but the plane that completed the flight was a single-aisle jet. For decades, flying the distance was synonymous with jumbo jets, but today narrow-body aircraft are now proving they are up for the task — and maybe even the best option. In this episode, Cheddar examines why airlines are betting on narrow-body aircraft.
Design Disasters Of The Human Body
Humans are scientifically the most successful species in the history of planet earth. And for this we can thank our opposable thumbs, proportionally large brains, and our upright posture. But for all our anatomical wonders, we still have some pretty major flaws.
