Crumbling crests

The Lewis Glacier once covered one of Mount Kenya's slopes.

The imposing mass of ice visible in archive photos has now been reduced to just two blocks — the biggest only a few dozen meters wide.

Muchiri said he fears the glacier will be entirely gone in a few years, transforming the landscape and discouraging visitors.

His observations are backed up by numerous studies, while scientists have found that ice loss from the world's glaciers has accelerated over the past decade as the planet warms.
