Scientists at the California Institute of Technology and the Chinese Academy of Sciences have discovered a new way to track the global warming of the Earth's oceans: using sound. Due to the sheer volume and depth of the ocean, it is extremely difficult for scientists to obtain accurate temperature measurements. Processes are already in place to take these measurements, such as using thousands of automated floats, though they have their inaccuracies as well.

1. 94% of life on earth is found in the ocean.
2. On top of this, 50% of the United States lays underwater.
3. Men's cosmetics are nothing new, Roman-era men wore lipstick to signify their high social status.
4. It only takes 8 minutes for a photon to travel from the Sun's surface to the Earth. This same photon would require 40,000 years to travel from the Sun's core to the surface.
