I love standing on a bridge and watching a river flow beneath my feet. But it makes me worried to see the fastest ice river in the world accelerating.
Glaciologists who track the Jakobshavn Glacier in Greenland say it has reached a summer speed of 17 km per year - four times faster than 20 years ago. The glacier is dumping more ice into the ocean, contributing to sea-level rise. I hope it will slow down. I prefer to watch a flowing river than a rising sea.
