It’s the sky that’s grown more unreliable. Fierce storms and erratic winds are increasingly common with climate change. But the rise in clear-air turbulence, often far from storms and undetectable by radar, is especially alarming. Since 1979, clear-air turbulence has increased by as much as fifty-five per cent over the North Atlantic and forty-one per cent over the United States. If temperatures continue to rise unabated, it could more than double by the middle of the century. Death by turbulence is still vanishingly rare, but Flight SQ321 did have one fatality. Geoffrey Kitchen, a retired insurance salesman from Bristol, England, on holiday with his wife of fifty years, died before the plane landed. Its sudden plunge had come as such a shock, it seems, that it gave him a heart attack.
