Weekend All Things Considered

On a muggy summer afternoon in Greenpoint, Brooklyn, a dozen people are hard at work on the patio behind a local church. They're stripping old bicycles of their brakes, cables and chains, and sanding and spray-painting them white.

But behind the lighthearted chatter, there's a more somber purpose to this gathering: They're building "ghost bikes."

Painted all white and adorned with colorful notes and flowers, ghost bikes are the cycling community's equivalent of roadside shrines dotting the highway; they mark the spot where a rider was killed in traffic.

While many cities around the country grapple with drought and excessive heat this year, city planners in Boston have something else on their minds: the prospect of rising water.

In this coastal metropolis, scientists and computer models predict that climate change could eventually lead to dramatic increases in sea level around the city. Coupled with a storm surge at high tide, parts of the city could easily end up under water.

In Nairobi, Kenya, when friends want to celebrate a birthday, the end of bachelorhood or a graduation, they often go out for goat. This communal and culinary tradition in Kenya is called nyama choma — literally, roasted meat. While it's usually goat, some places offer beef, chicken and lamb. If you know where to look, you can even get illegal zebra and and wildebeest meat.
