The Greenland Ice Sheet and associated outlet glaciers are melting at an alarming rate due to rising global temperatures.
Katla Volcano is covered by several hundred meters of ice from the Mýrdalsjökull Glacier in southern Iceland. This active volcano has an eruption interval of 20–90 years, causing massive mud flows, or jökulhlaup, when the subglacial eruptions melt the massive ice cap from below.
Boardwalks are assembled for tourists to navigate the unstable ground and access the Katla Ice caves in safety.
