Spring came early this year in the high mountains of Gilgit-Baltistan, a remote border region of Pakistan. Record temperatures in March and April hastened melting of the Shisper Glacier, creating a lake that swelled and, on May 7, burst through an ice dam. A torrent of water and debris flooded the valley below, damaging fields and houses, wrecking two power plants, and washing away parts of the main highway and a bridge connecting Pakistan and China.
Pakistan’s climate change minister, Sherry Rehman, tweeted videos of the destruction and highlighted the vulnerability of a region with the largest number of glaciers outside the Earth’s poles. Why were these glaciers losing mass so quickly? Rehman put it succinctly. “High global temperatures,” she said.
Just over a decade ago, relatively little was known about glaciers in the Hindu Kush Himalayas, the vast ice mountains that run across Central and South Asia, from Afghanistan in the west to Myanmar in the east. But a step-up in research in the past 10 years — spurred in part by an embarrassing error in the Intergovernmental Panel on Climate Change’s 2007 Fourth Assessment Report, which predicted that Himalayan glaciers could melt away by 2035 — has led to enormous strides in understanding.
