Last September I took a flight from Boston to Yerevan, the capital of Armenia, a country I had barely heard of and knew even less about. Tucked in between Turkey, Iran and a handful of former Soviet republics, it is an arid plain with a history of invasion and cross-invasion.

It is also home to the Lesser Caucus Mountains, part of the mountain range that divides Europe from Asia. I was there on an American Alpine Club climber exchange, teamed up with Americans, Armenians and Iranians climbing our way across Armenia and Georgia, everything from single-pitch sport and trad routes to alpine snow and ice up 5,000 meter peaks. It was a tremendous three weeks, one full of new friends and meaningful connections.

One of the mountains we climbed along the way was Mount Aragats, the tallest peak in Armenia. (Historically Mount Ararat was the tallest peak in Armenia, but it’s now part of Turkey, and the border is closed. This is a painful fact for Armenians.) Aragats has four distinct summits, the north being the tallest at 13,420 feet. Climbing it means clambering over loose shale and boulders to windswept ridges. Most of the mountain feels unstable, like stacked blocks barely held together. There was one small patch of snow tucked beneath the southern and western summits, but otherwise it was dusty, dry and hot.

Historically, however, the snows of Aragats have held through the summers. They have kept creeks flowing in hotter months. Prior to escalating global temperatures, Aragatan snowfields would last through the year and provide a stable source of water through dry times.

Today, however, high temperatures melt things quickly, leaving the valleys flooded in the spring and parched by fall.

This short documentary by Armenian filmmaker Vardan Hovhannisyan lays out what is happening, and what local scientists are trying to do about it:

 

Yep. Thermal blankets. Several of us noticed them on our descent—white mounds squirreled away beneath the south summit. We didn’t realize what they were, that they were an attempt to save Aragats’ last few patches of snow. I remember discussing them when we got back to camp, but no one could tell exactly what they were. Now we know.

Blankets. Is that the solution to global warming? For now, the answer in Armenia seems to be yes. But it’s a lot of pressure for a few swath of fabric. What if the blankets insulate too well? Or not well enough? How many do they need to makes sure there is enough water? Do they have to cover the mountain? What happens if things don’t last through the summer?

These are complex questions, ones previously left to nature to ponder. But lately her answers have left Armenians parched. Now it’s up to Armenian scientists to see if they can do better.

When we were there in September our team didn’t know the difference. We didn’t realize we were walking over fields usually covered with snow. We scrambled the bare rocks unaware they normally would be entombed by snow.

To us Armenia was just dry. Now we know why.
