TOOLIK LAKE, Alaska — As Alaska's climate changes, almost every veteran researcher at Toolik Field Station, the Arctic research center just north of the Brooks Range, has a story about lightning.

Linda Deegan, a senior scientist at Woods Hole Research Center in Massachusetts, was enjoying a beer by Toolik Lake when she saw her first strike. She remembers uttering an expletive when she saw it.
