Good morning, and happy Monday. Here are some of the stories we're following today:

One hundred and thirteen entertaining, but scoreless, minutes passed before Germany's Mario Gotze scored in extra time to finish off the 2014 World Cup in Brazil.

More than two years after the cruise ship sunk off the coast of the Italian resort island Giglio, Costa Concordia will float again for one last time.

6. Disney World’s monorail halted by possible lightning strike

It's not supposed to be a thrill-ride, but Disney's monorail came with some extra excitement on Sunday night when it was stopped by a possible lightning strike.

7. If shark populations are on the rise, will attacks increase?

The shark population is up, but the Jaws music might not have to be cued. Sharks play an important role in the ocean, and evidence does not support that more sharks equals more attacks. What does lead to more shark attacks is human behavior like swimming in the same area you've cleaned fish, or wearing bright clothes in the water. Read more in #SHARKWATCH.

Italy's Luca Paolini was called out by a sports photographer for the deed. Texting and riding is arguably just as dangerous as texting and driving, at 40 mph.
