The mountain climbing industry has transformed the lives of the Sherpas – both for good and bad. A new book focuses on their lives and deeds.
This is an enhanced satellite image of Western Australia’s Great Sandy Desert. Yellow sand dunes cover the upper right, red splotches indicate burned areas, and other colours show different types of surface geology.

Mountains can’t be created without lubricant, and 2 billion years ago that lubricant was graphite produced by the carbon broken down from layers of dead plankton on the ocean floor.
Dams built in an earlier age are suddenly vulnerable as the climate shifts.

Scientists studied charcoal layers in the sediment of lake beds across the Rockies to track fires over time. They found increasing fire activity as the climate warmed.
Heat and dryness are leaving high mountain areas more vulnerable to forest fires.

Everest didn’t become the highest mountain overnight. This process was excruciatingly slow; a result of complex interactions between the solid earth, the atmosphere and the biosphere.

Pikas – small cousins of rabbits – live mainly in the mountainous US west. They’ve been called a climate change poster species, but they’re more adaptable than many people think.

The parable of the dragons underlines the need to apprehend glacier disappearance in a transdisciplinary way, to create a dialogue between the physical, ecological and philosophical sciences.
Early humans called Denisovans lived in a remote mountain cave between 100,000 and 60,000 years ago, and possibly longer still, raising intriguing questions about their relationship to modern humans.
