Anchored by Jake Tapper, The Lead airs at 4 p.m. ET on CNN.
The latest on the crisis in Ukraine, plus a look at the key 2014 Senate races.
(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) – If there's one thing the communists really excelled at, beyond murdering millions of people, it was propaganda.
The Soviets turned indoctrination into an art form that's still appreciated by some today as just that.
From Crimea to the tense standoff in eastern Ukraine, it is clear Moscow is taking a page from those old masters and bringing the fight to the airwaves.
Three different Russian television channels reportedly aired three versions of an interview with the same man, identified three very different ways: as a German spy, a repentant extremist, and a pediatric surgeon, according to a report by Forbes.
"I was there in 1968, a teenager in Moscow, and I don't recall the level of propaganda reaching this amount of frenzy, and brazenness, and hysteria," says Leon Aron, director of Russian studies at the American Enterprise Institute.

(CNN) – It's not about the technology, says Twitter co-founder Biz Stone.
Seems like an odd statement, coming from a man who co-founded a social media platform that helped bring governments to their knees. But in his new book "Things a Little Bird Told Me," Stone describes his last day at Twitter, writing about how upsetting it was to learn the company was doing a town hall meeting with President Barack Obama.
Stone wanted Twitter to be government neutral.
"I just have this general philosophy that it's really all about people, not technology. I believe in the triumph of humanity with a little help from technology," Stone said in an interview with CNN's "The Lead with Jake Tapper."
"Whenever things happen around the world and Twitter gets mentioned along with it, I always try to make sure people see it's people that are doing this. You know, when the Berlin wall fell, it wasn't like AT&T was like, 'Hey they used phones! Phones helped!'" said Stone.
(CNN) – Russian Prime Minister Dmitri Medvedev described the standoff playing out right now in eastern Ukraine as "on the threshold of a civil war."
In the same region, the Ukrainian military has now mobilized what its fledgling government is calling an "anti-terrorism" operation against pro-Russia protesters holed up in government buildings along the border.
The Ukrainians say they've now recaptured an eastern airport, in a move the Russian media says cost four people their lives and left two more injured.
Meanwhile, Google has been symbolically drawn into the conflict after updating its Google maps service, for Russian users only, showing what was once the Ukrainian peninsula of Crimea, as now being just another part of Putin's playground.
(CNN) – U.S. officials say a Russian fighter jet made a dozen low-altitude passes on the USS Donald Cook in the Black Sea this weekend, in what could be the most direct confrontation between the United States and Russian forces in years.
Officials say the plane appeared to be unarmed, but the Pentagon is still calling the fly-by "provocative and unprofessional."
And if that's not reminiscent enough of the Cold War, CIA Director, John Brennan was in Kiev this weekend, a fact confirmed today by White House Press Secretary Jay Carney, even though the Central Intelligence Agency had already refused to comment on Russian media reports that Brennan was there.
Meanwhile, the crisis on the ground threatens to spill over. Pro-Russia protesters have control of the police headquarters of another eastern Ukrainian city, and are refusing to blink, as the ultimatum from the Ukrainian government passed without consequence.
