I lost track of how long we trudged through the snowstorm. All I could keep count of were my footsteps, as a way of pushing myself on. Every time I reached 100 I allowed myself to look up, exposing my face to the freezing wind to see if there was any sign of our destination. But, for what seemed like hours on end, there wasn't. All I could see was a never-ending expanse of swirling white.
We were 5400 metres above sea level, on a glacier in the Peruvian Andes, heading towards a research camp where Lonnie Thompson, the world's preeminent glaciologist, and his team were drilling into the ice core. Lonnie's discovered that glaciers are melting at a rate which was previously inconceivable. As they disappear they will take most of the world's fresh water supply with them.
Hard to imagine an ice-free world when you are traversing a glacier. Sometimes the only thing that kept my legs moving was the rope attaching me to the mountain guide, Americo. He walked ahead, prodding the snow with an axe. Often it would give way to reveal a deep crevasse. The more regular appearance of new ones is an ominous sign of global warming.
I felt so insignificant and small up on that massive glacier. But now, it too is helpless in the face of climate change. Up on it, there were times when I felt as if we were literally on top of the world. But with every crevasse that Americo uncovered I was reminded of how fragile things are and how quickly we could fall to the bottom.
Water security is going to be one of the most pressing issues as the world faces the challenge of climate change. If average global temperatures rise by only a few degrees most of the world's glaciers will all but disappear, leading to floods and severe water shortages for millions of people. “Hot Cities” goes to Lima in Peru, one of the driest cities in the world, which relies heavily on the water from three rivers fed by glacial melt.
