Nick Kristoff departs his usual beat to remind us once again (not yet enough it appears) of the effects of climate change — high mountain glacier melt.

[David] Breashears first reached the top of Everest in 1983, and in many subsequent trips to the region he noticed the topography changing, the glaciers shrinking. So he dug out archive photos from early Himalayan expeditions, and then journeyed across ridges and crevasses to photograph from the exact same spots.

The pairs of matched photographs, old and new, are staggering. Time and again, the same glaciers have shrunk drastically in every direction, often losing hundreds of feet in height.

“I was just incredulous,” he told me. “We took measurements with laser rangefinders to measure the loss of height of the glaciers. The drop was often the equivalent of a 35- or 40-story building.”

See particularly the comparison photos of the Kyetrak glacier in Tibet.  As Kristoff says:

We Americans have been galvanized by the oil spill on our gulf coast, because we see tar balls and dead sea birds as visceral reminders of our hubris in deep sea drilling. The melting glaciers should be a similar warning of our hubris — and of the consequences that the earth will face for centuries unless we address carbon emissions today.

See the Asia Society show he refers to.
