How has Everest changed since the early 2000s?

Question

Accepted Answer

Mount Everest has experienced a notable reduction in snow cover and an increase in exposed rock since the early 2000s.

British climber Kenton Cool, who has summited Mount Everest 17 times, observed a significant decrease in snow on the mountain compared to his early expeditions in the mid-2000s. This observation is corroborated by his experience of witnessing rock falls on the Lhotse Face, a phenomenon he had not encountered previously, indicating a trend towards a drier and more rocky mountain.
Reduced Snow Cover and Increased Rock Exposure

Kenton Cool, who first climbed Mount Everest in 2004, has noted a distinct shift in the mountain's conditions over his 17 ascents. He stated that in the early to mid-2000s, there was considerably more snow, and the general trend now is for the mountain to be "more rocky and less snow." This change is not uniform year-on-year but represents a discernible pattern.
Evidence of Increased Dryness Through Rock Falls

The increased dryness of Mount Everest is evidenced by the rock falls observed on the Lhotse Face, a critical section of the route to the summit. Cool reported experiencing rock falls of a type and frequency he had not seen before, which he directly linked to the current arid state of the mountain. He suggested that this lack of snowfall and precipitation could be a consequence of global warming or other environmental changes.
Broader Environmental Context and Warming Trends

The observed changes on Mount Everest align with broader scientific findings regarding climate change. Climate scientists report that global temperatures have risen by an average of 0.74 degrees Celsius over the last century. However, the warming trend in the Himalayan region has been more pronounced than the global average. Nepal, in particular, is experiencing an average temperature increase of 0.06 degrees Celsius annually, a situation partly attributed to its geographical position between major industrial polluters, China and India.
