Where AI can help fight climate change – and where it can't

High above the valley in California's wine country, Joanna Wells' vineyard is a challenging place to grow grapes. It's nearly 3,000 feet above sea level, atop a mountain ridge, "Forty minutes off a main road just to get there," Wells says. But it's these rocky hilltop terrains, with plenty of sunshine and maritime breezes, that Wells says, are perfect for the job. What's not idyllic, though, is California's extreme weather. "Every year tends to be climatically extreme now."
