When one thinks of the damage that climate change is doing, it’s probable that what comes to mind is a vision of huge lumps of ice dropping off one of the polar ice sheets and crashing into the ocean. While Greenland and Antarctica are losing masses of ice, so too are most of the glaciers around the world, but it’s tricky to measure how much ice they are shedding.

Thanks to ESA’s CryoSat satellite and a breakthrough way of using its data, scientists have discovered that glaciers worldwide have shrunk by a total of 2% in just 10 years, and it’s because of higher air temperatures.
