Measurements from three satellites showed that on July 8 (right) about 40 percent of the ice sheet had undergone thawing at or near the surface. In just a few days (July 12), an estimated 97 percent of the ice sheet surface had thawed. The areas classified as “probable melt” (light pink) correspond to those sites where at least one satellite detected surface melting. The areas classified as “melt” (dark pink) correspond to sites where two or three satellites detected surface melting.

Scientists say there has been a freak event in Greenland this month: Nearly every part of the massiveice sheet that blankets the island suddenly started melting.

Even Greenland's coldest place showed melting. Records show that last happened in 1889 and occurs about once every 150 years.

NASA says three satellites saw what it calls unprecedented melting over four days beginning July 8. Most of the thick ice remains. But what was unusual was that the melting occurred over a widespread area.

NASA says the melting area went from 40 percent of the ice sheet to 97 percent. Until now, the most extensive melt seen by satellites in the past 30 years was about 55 percent.

Scientists cannot say yet if the melting is from global warming or natural.

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
