...leave Copenhagen's airport, you see soaring wind turbines along the side of the road, spinning in the nearly always present breeze. Get used to the sight - Denmark is a world leader in wind energy, and produces more than 10% of its power from turbines. That's meant cleaner air and greener jobs. The homegrown wind company Vestas is a world leader earning $8 billion a year, an impressive figure in a country that has barely half the population of Hong Kong. The taxi ride into the city won't take long either - some one-third of urban transport within...
...what they bring back is not solid ice, but a half-snow, half-ice substance called firn. It's solid but porous, so it can trap some of the gas present in the atmosphere when it accumulated as snow. They can tell how much carbon dioxide was in the air during a given time period (roughly seven years with each layer, because in the porous firn - unlike the frozen ice below - air from different years can mix over time), and by analyzing oxygen isotopes inside the firn, they can tell the temperature as well. Johnsen and Hansen bring a core...
...will be done. That won't take place until next summer, but the scientists have already dug out a deep trench where the main drill will bore to the bottom of the ice. Here the cores will be pure ice, inside which gas will be trapped in tiny bubbles - air from over 100,000 years ago. Pulling up those cores will take three years, longer to fully analyze the ancient gases found inside them...
After a series of post-dinner presentations, we drink whiskey cooled by ice cubes cut from some of the spare cores, dating back to 1816 exactly. One by one we head off to our assigned sleeping tents, bunk bags and bags, where the air is only a little warmer than it would be outside. I suppose my body clock has caught up with wherever I am, because I fall asleep immediately, and deeply. I wake up once in the middle of the night to use the bathroom, and stagger outside, shivering. It's 2 a.m., and the sun is bright...
...member church is open seven days a week, its air-conditioned fellowship hall serving as a sort of neighborhood cooling center. Over the last month, the church hosted a "community ministers" program in which college students supervise youths on work assignments such as planting flowers and collecting trash. The recent Friday Movie Night and Variety Show drew some 200 kids. In the fall, the church sponsors ACT- and SAT-prep courses, and hires college students as role models. "You go one block, and you're smack dab in the middle of the negative pathologies," Hatch says. "Outside of here, academic...
