(CNN) – Climate change is a polarizing issue. So photographer James Balog traveled towards Earth's poles to bring back tangible, visual, and hauntingly beautiful evidence of a dramatic geological event that affects every human being on this planet.
In the award-winning documentary "Chasing Ice," Balog and his team braved some of the globe's most extreme conditions to reach glaciers in Greenland, Iceland, Alaska, and Montana, and brought back years' worth of time lapse photography. Balog's cameras have been there to watch as hunks of ice bigger than lower Manhattan just disappear.
(CNN) – There is still a sliver of hope the underwater autonomous vehicle, the Bluefin-21, will find signs of missing Malaysia Airlines flight MH370. But that hasn't stopped investigators from regrouping, and reconsidering the search.
The underwater search vehicle is on its 10th mission to find the flight's black boxes or any other plane wreckage.
But it's running out of places to look. It has already covered two thirds of the 6-mile radius where those possible black box pings were detected.
In the event that nothing is found once the entire area is searched, Australian and Malaysian officials want to have the next steps already in place.
Investigators are now game-planning their next move and they're considering widening their search, and possibly bringing in new tools to help.

Jindo, South Korea (CNN) – The first distress call from the ferry Sewol came not from the crew, but from a boy who used a cell phone to contact emergency services from aboard the sinking ship, the South Korean coast guard confirmed to CNN Tuesday.
CNN affiliate JTBC reported that the boy dialed South Korea's emergency number, telling dispatchers for a local fire service, "Help us. The boat is sinking." The boy's fate was not clear.
(CNN) – The underwater drone searching for Malaysia Airlines flight MH370 is nearly done scanning the search area in the Indian Ocean – and still no sign of the plane's wreckage or data recorders.
The Australians say they expect "further refinement" in the data, that could lead to the search area being tweaked again in the next few weeks.
CNN analyst and ocean search specialist Rob McCallum, and CNN aviation analyst and attorney for victims and families of transportation accidents Mary Schiavo discuss.
(CNN) – As seen in the countless images and videos of distraught family members, the search for missing Malaysia Airlines flight MH370 has taken its toll emotionally.
But it also has a financial cost.
Now that a U.S. time limit for when lawyers can contact family members has passed, will families take more action?
