The IPCC has released a special report assessing how the world’s ice and oceans are faring under our changing climate, and scientists may be one step closer to a cure for the common cold!

Some people argue that the Polar Vortex is evidence against global climate change, but there’s actually growing evidence that a warming Arctic means colder winters.

Some people tout the health and productivity benefits of cold showers, but how much do they really do?

Scientists first saw patches of ice on Mercury 20 years ago, and that discovery raised a lot of questions: How could ice survive on one of the solar system’s hottest planets, and how did it get there in the first place?

Squeaks almost lost a balloon outside, but what would have happened to it had it floated away into the sky?
