Brian Stone Jr., director of the Urban Climate Lab at Georgia Tech, says that pavement stores heat during the day and makes cities hotter at night. Cities, he says, tend to be heating up at double the rate of the rest of the planet.
Green spaces and water features, like this new one behind Ponce de Leon Avenue in Atlanta, are ways cities can help combat rising temperatures. Trees provide shade, and evaporating water helps cool the air.
More than 20,000 high-temperature records have been broken so far this year in the United States. And the heat is especially bad in cities, which are heating up about twice as fast as the rest of the planet.
High temperatures increase the risk of everything from asthma to allergies, and can even be deadly. But a researcher in Atlanta also sees this urban heat wave as an opportunity to do something about our warming planet.

The bus is always the center of attention. Partly because it's a hulking 1970s tour bus that somehow made it from Arizona all the way to Charlotte, but mostly because of what's inscribed on the side of it in thick, black letters.
"Sin Papeles, Sin Miedo," it reads in Spanish. "No papers, no fear."
Carrying a bunch of undocumented activists, the bus rolled through the country, through states like Arizona, Texas, Louisiana and Georgia, and into Charlotte on the eve of the Democratic National Convention.

Actor Michael Clarke Duncan has died at age 54, according to his fiancee, the Rev. Omarosa Manigault. Known for his huge size and deep, resonant voice, Duncan received an Oscar nomination for his performance in The Green Mile, the 1999 prison film in which he starred alongside Tom Hanks.
Duncan's death was announced by Manigault, who in July said that she performed CPR on the actor after finding him in a state of cardiac arrest late at night.
Is Mitt Romney shifting his abortion position again?
It's fairly well-known that Romney proclaimed himself in favor of abortion rights when he ran for office in Massachusetts, then reversed himself before launching his presidential bid. But recently, the GOP nominee seems to be softening his opposition somewhat. Or is he?

The astronomer in me will tell you that summer officially ends on Sept. 22. That's the date of the Autumnal Equinox, the point in Earth's orbit where the hours of day and night are equal. That definition is fine for a scientific understanding of the cosmos, but when it comes to experience, we all know that summer really ends on Labor Day. And in that division between the ways we meter time (for science or business) and the way we actually live time, there is a Labor Day lesson we might keep close to our hearts all year long.
Afghan girls walk home from school in Kunduz province earlier this year. Despite progress in recent years, girls who want an education face threats from the Taliban and other extremists, and sometimes even their own families.
In Afghanistan, girls are required by law to go to school. However, many of them never do.
Death threats, acid attacks and bombings by Taliban militants and other extremists lead many parents who support female education to keep their daughters at home.
Sometimes, it's the families themselves who stand in the way. School officials in conservative communities say relatives are often more interested in marrying off their daughters or sisters than in helping them get an education.
But some girls, like 18-year-old Rahmaniya, are fighting back.
Crowd funding began as a way to support the arts on the Internet. Artists could go online to pitch a new album, for example, in the hope that thousands would give small amounts. But now it's expanded to entrepreneurs, and the rules aren't quite as clear.
Syrian air force jets bombed the rebel-held town of Al-Bab in northern Syria on Monday, killing at least 18 people, according to Syrian activists.
Over the summer, the rebels gained control of a number of towns and villages along the Syrian-Turkish border. Now, those places are being bombarded from the air and from the ground by government forces.
Azaz, in northern Syria's Aleppo province, is one of these places. There, the tombstones in the old section of the town's cemetery are laid out in neat rows.
