...global warming making the problem worse? Superficially, the numbers say yes-or at least they seem to if you live in the U.S. From 1995 to 1999, a record 33 hurricanes struck the Atlantic basin, and that doesn?t include 1992?s horrific Hurricane Andrew, which clawed its way across south Florida in 1992, causing $27 billion dollars worth of damage. More-frequent hurricanes are part of most global warming models, and as mean temperatures rise worldwide, it?s hard not to make a connection between the two. But hurricane-scale storms occur all over the world, and in some...
...moment evidence of harm comes to light. But in the desert there's not a lot of margin for error, and a chronic water imbalance can be environmentally devastating. Robert Hershler, a taxonomist at the Smithsonian Institution, has combed through the biota of hundreds of springs in the Great Basin region, including Snake Valley, and has discovered more than 100 new species of spring snails, some of which are confined to a single location. "If their spring dries up, these snails are gone for good," he observes. "They can never come back...
Even if Las Vegas had not come calling, Great Basin water holes would be in trouble. Across the region, drought, agricultural diversions and overgrazing have done measurable damage, and there are examples in Snake Valley. "We're worried about southern Nevada because we know what we're doing to ourselves," says rancher Dean Baker. "And that's just a drop in the bucket compared to what they're talking about...
...toward the shallows north of the original crater. Some 1.8 million years ago, the atoll contained an inland sea continually replenished by ocean waters. But as the rising coral walls gradually closed out the ocean, newly deposited sediments' piled up in the forming lagoon. The inland sea shrank, the basin filled with fresh water and, in the warm southern sun, soon became clogged with the rich grasses that formed the Everglades. Central Florida's Lake Okeechobee, says Petuch, is the last remnant of that great, sediment-filled lake...
Harvard’s home waters, the Lower Basin of the Charles, froze over during holidays and didn’t thaw until late, putting the Crimson at a disadvantage by inhibiting practice...
