How melting glaciers fueled Pakistan’s fatal floods

by BENJI JONES

Pakistan has more than 7,000 glaciers. Climate change is melting them into floodwater.

Much of Pakistan is now underwater.

A series of extreme floods has utterly devastated the South Asian nation, which is home to some 225 million people, washing away roads and buildings, destroying farms, and stranding hundreds of thousands. Over the weekend, which brought another bout of torrential rain, government officials said the death toll had soared past 1,000 and water had inundated as much as a third of the country.

The main fuel for these catastrophic floods is rainfall. Summer is monsoon season, and this has been a particularly wet and wicked one, perhaps made worse by climate change.

But there’s another culprit behind the recent devastation: melting glaciers and snow.

Pakistan is home to over 7,200 glaciers, more than anywhere outside the poles. Rising temperatures, linked to climate change, are likely making many of them melt faster and earlier, adding water to rivers and streams that are already swollen by rainfall.

“We have the largest number of glaciers outside the polar region, and this affects us,” Pakistan’s climate minister Sherry Rehman told the Associated Press. “Instead of keeping their majesty and preserving them for posterity and nature,” she said, “we are seeing them melt.”

That means that Pakistan — already one of the countries most vulnerable to climate change — will become increasingly susceptible to flooding as the planet warms. It’s an unfortunate reality for a country responsible for just a tiny fraction of global greenhouse gas emissions, underscoring how the harm caused by big polluters is often exported. Like many countries, Pakistan will bear an unequal burden of climate change in the years to come.
