At sea lake in Western Victoria, Bob McClelland is harvesting wheat and grateful to be doing it. Thanks to a little rain and a pipeline from the Murray River, McClelland's farm is surviving the six-year drought that's parched much of southeast Australia. He isn't sure if it's just one of the region's periodic dry spells or if, as some scientists say, it's been worsened by global warming. But "I'm a bit of a believer in climate change," he says. "All those Arctic glaciers melting there must be something happening."
