...Iron Ocean...
...reasons the oceans soak up so much carbon is that phytoplankton--microscopic floating plants--love it, feasting on it and taking it out of circulation. The problem is, there are vast regions where the water is iron poor and plankton languish. The amount of iron the plants need and aren't getting is tiny--less than 20 lb. per sq. mi. (3 kg per sq km) by some estimates. If this were pumped as a diluted slurry into the wake of a ship steaming back and forth like a tractor seeding a field, the plankton would bloom and global...
Sometime next year, a California start-up called Climos plans to experiment with the technique, fertilizing about 4,000 sq. mi. (about 10,000 sq km) of ocean. The goal is not to prove that the iron makes the plankton grow but to determine how much carbon this takes out of the atmosphere and for how long. "When we add iron, we create plankton blooms," says oceanographer Ken Buesseler of the Woods Hole Oceanographic Institution, who led an earlier, smaller iron-seeding test, "but a lot of that just dies and decomposes" at the surface. Only when organic matter snows...
...single tall fence, until it reaches the rugged Gila mountains. Beyond the range, the fence resumes, but now it's in the deep Sonoran Desert. The design here is steel posts, about 4 ft. (1 m) high, filled with concrete to thwart plasma torches and linked by surplus railroad iron. This fence is intended to stop cars, not walkers--but anyone crossing out here must be ready for a parched hike of 30 miles (48 km) or more, through cactus lands and bombing ranges, to the nearest road. That's a dwindling population, said CBP helicopter pilot Gabriel Mourik...
...holes." There's a vehicle barrier south of the tiny town of Menninger's, but drug smugglers use hydraulic ramps to boost cars over for a quick dash into town. In the rolling pasturelands east of Nogales, the fence is a so-called Normandy barrier of crisscrossing railroad iron. Smugglers like to cut this fence with torches, then carefully put everything back in place so the border patrol won't notice. In parts of the sector there is still no fence at all. This includes a 28-mile (45 km) stretch near Sasabe where a multimillion-dollar pilot project...
