Icelandic glacier loss

Guest post by Jenny Snell Icelandic glaciers, like those in many regions around the world, are melting fast1. Ice margins are retreating, and lakes are forming at these margins, called proglacial lakes1. These lakes speed up the loss of ice, change the flow of sediment through rivers, cause coastal erosion and can create a risk …

Why are glaciers important?

Glaciers are important for their beauty, cultural importance, ecosystem services such as water resources, economic value, and potential to raise global sea levels. This is an impassioned plea to recognise the value of our glaciers worldwide, and to protect them to the best of our ability. Globally shrinking glaciers Glaciers exist in pretty well every …

Evidence of global glacier recession: repeat photographs and satellite imagery

Globally, glaciers are receding, one of the most visual and striking pieces of evidence of the way in which climate change is affecting our planet. The evidence is clear, both in satellite imagery, digital elevation models, and repeat glacier photography. Global scale remote sensing Worldwide, glaciers are shrinking. We know this from satellite measurements, that …
