Red coal trucks zip up and down narrow dirt tracks, churning up clouds of dust in China's remote Gansu province. Nearby, the towering stanchions of a new railway bridge rise out of a muddy river winding through the hills. The Huaneng Group, one of five big Chinese state utilities, is building a $1.9 billion 4 gigawatt coal and power project in the northwestern region near the city of Qingyang, with the aim of delivering its electricity to the east of the country. The Zhengning Power Plant Project, which was revived in July four years after it was put on ice, encapsulates the competing pressures that lie behind China's economic and climate policies.

Owner Arturo Azinian poses for a portrait in his shoe repair shop in Beverly Hills, California April 24, 2015. Azinian is an 88-year-old Beverly Hills cobbler famous for saving the fancy footwear of the elite in the ritzy 90210 zip code. Just steps from boutique-lined Rodeo Drive sits the decidedly unglamorous Arturo's Shoe Fixx, where Azinian, an Argentine immigrant, toils for 13 hours a day in a warren of whirring machines and shoes stacked to the ceiling. While handling shoes worth hundreds and thousands of dollars, Azinian is utterly clueless about the famous people to whom they belong.

A view of a multi-million dollar home in foreclosure on Rexford Drive in Beverly Hills, California February 3, 2012. Some 180 houses in the 90210 zip code have been foreclosed on by lenders, scheduled for auction, or have been served with a default notice, the highest level since the 2008 financial crash, according to a Reuters analysis of figures compiled by RealtyTrac, which tracks foreclosures nationwide. But the dynamics of the residential real estate collapse are very different in elite neighborhoods such as this. The majority of delinquent homeowners here owe more than $1 million. Many are walking away not because they can't pay, but because they judge it would be foolish to keep doing so. Picture taken February 3, 2012.

A powerboat motors through the busy inner harbour in Stockholm August 8, 2007. You need a licence to drive a car or fly a plane, but in Sweden just about anyone can take the helm of a 200 horsepower speedboat that zips along at speeds up to 70 km (44 miles) an hour. That could change if a plan to make boaters apply for licences becomes law. The result, sailors say, could be a more bureaucratic, rule-bound sea around Sweden's rugged coasts -- but also a safer one. Picture taken August 8, 2007.
