Glaciers are what we often think of when we think of global warming. We see before/after photos showing how much glaciers have melted in the past few decades as evidence of climate change.

Photographer Simon Norfolk shows us the changes in Mount Kenya’s Lewis Glacier using fire lines—long exposure night photographs with a gasoline-fueled torch to show where the glacier used to lie in previous years, in comparison to where it is today.

Mount Kenya is Africa’s 2nd highest mountain (17,000 feet). The Lewis glacier has retreated by 90% since it was originally mapped in 1934, and it is estimated the glacier will be completely gone in another 10-12 years.

Climate change and the melting of the Lewis Glacier on Mount Kenya.
The flame line shows the Lewis Glacier’s location in 1934. The glacier has since receded about 275m. In 1934 it carried on almost to the top of the peak on the right and covered the left side of the picture as high as the break in the scree slope, just below the vertical ‘wall’ that leads to the summit.
The rounded peak on the left is Point Thomso
