Juneau is an example of a climate “feedback” in action: as temperatures are rising, less and less snow is remaining through the summer .
This in turn leads to ice being exposed to sunshine and higher temperatures, which means more melt, less snow, and so on.
As the plateau of the icefield thins, ice and snow reserves at higher altitudes are lost, and the surface of the plateau lowers.
Work like this is crucial as the world’s glaciers are melting fast—all together they are currently losing more mass than the Greenland or Antarctic ice sheets, and thinning rates of these glaciers worldwide has doubled over the past two decades . Our longer time series shows just how stark this acceleration is. Understanding how and where “feedbacks” are making glaciers melt even faster is essential to make better predictions of future change in this important region.
