Vanishing Ponds of The Arctic

Introduction

Warming Temperatures are shrinking ponds in the Arctic tundra. Rise in  temperature thaws nutrient-rich permafrost, releasing nutrients into ponds and enhancing plant growth, which takes over shallow ponds. More than 2,800 ponds in the northern region of Alaska's Barrow Peninsula were analysedwith photos and satellite images between 1948 and 2010. The number of ponds had decreased by 17 per cent, while pond size had shrunk by an average of one-third.
