A fleet of unmanned boats is traveling from the Arctic to the equator, gathering vital data on climate change.

The autonomous vessels -- called "Saildrones" -- resemble bright red surfboards. Each is fitted with a 20-foot-high carbon fiber sail, and 16 sensors that test variables including carbon dioxide, acidity, currents and water temperature.
