Scientists Look for Climate Trends in High Places

Scientists gather on Freel Peak to take a census of the plants on the summit.

Mountaintops can be good places to study the effects of climate change because there aren’t any things like factories or highways or garden weeds up there. In that way, they’re more like laboratories.

So, even though it involved a tough hike, about a dozen scientists gathered at the top of Freel Peak near South Lake Tahoe earlier this summer to count every single plant at the summit. It was for GLORIA, short for Global Observation Research Initiative in Alpine Environments, a project that sends botanists and plant ecologists to the world’s highest mountains to document the tiny, colorful plants that live on them.

GLORIA surveys are repeated every five years, and this was the second survey on Freel Peak. By tracking the changes here, scientists can gain a better understanding of how alpine regions differ in their responses to climate change, and what the future may hold for lower elevations.

“Because of the nature of the alpine habitat, it is more sensitive to environmental changes,” explained GLORIA coordinator Colin Maher. “It’s kind of a beacon. It’s like a warning sign. We might not know for 20 years what’s happening, but it’s a place where change is more likely to happen and we can detect it.” Continue reading
