The U.S. government has changed the number of refugees it plans to allow into the country. President Obama recently said that the U.S. would accept 10,000 additional refugees from Syria next year. The United Nations criticized that as not being enough.

Now, the U.S. Secretary of State John Kerry pledges that America will increase its refugee limit by an additional 15,000 next year and 15,000 again the year after, for a total of 100,000 worldwide refugees accepted into the U.S. per year. Many of the additional people would come from Syria.

It's not clear if the Obama administration can legally do this without approval from Congress. Some lawmakers are saying the U.S. should accept more Syrian refugees. Critics say that could come with security risks.

What is certain is that the number of people seeking asylum continues to grow and flow into Europe.

AZUZ: Along what's called the Eastern Route, more than 132,000 migrants have travelled mainly from Syria and Afghanistan. Along the so-called Central Route, more than 91,302. These are mostly people from Eretria, Nigeria and other parts of Sub-Saharan Africa. And along the Western Route, almost 6,700 migrants so far, most of them coming from Syria.

Through June of this year, asylum applications, the numbers of people seeking a safe place to say varied by country. But they range from tens of thousands to hundreds of thousands, and more than 2,700 people have died in the Mediterranean Sea trying to cross into Europe over water.

AZUZ: Quick update to the 2016 U.S. presidential race. Wisconsin Governor Scott Walker announced yesterday he's no longer a candidate for the Republican nomination. Governor Walker was a frontrunner when he entered the race in July, but after the first two Republican debates, his poll numbers were down and he withdrew last night.

That means there are now 15 people seeking the Republican nomination, five are officially seeking the Democratic nomination.

Crude oil is measure in barrels. Last summer, its global price was $100 per barrel. Yesterday, it was trading at less than half that, at about $46.50 a barrel.

Why does that matter?

Well, the price of crude affects everything from gas prices to car prices, to stock prices. And it determines the number of jobs in the large global oil industry. The current glut of oil, the surplus of it, gives us a clear lesson in the economic principle of supply and demand.

NARRATOR: When it comes to oil, it used to be all about the Middle East. Today, the Persian Gulf still has plenty of crude, but the boom is global.

We produced a surplus of 2 million to 3 million barrels per day. Oil buried deep beneath the earth surface in shale rock can now be accessed with new technologies like fracking and horizontal drilling.

In 2014, U.S. oil productions saw its biggest jump in more than 100 years, and it's not the only country to unleash a flood of crude. Production in Canada and Brazil has also hit record levels.

At the same time, there are more alternatives to oil, like natural gas and renewables. When oil supply outstrips demand, prices fall.

And cheap oil has consequences. It's great for consumers, costing less to fuel our cars and heat homes. But it can be tough for companies in the oil patch. It hurts profits and leads to job cuts. And the really sharp dip can unsettle global markets.
