<a href="//commons.wikimedia.org/wiki/Ama_Dablam" title="Ama Dablam">Ama Dablam</a> (6856 m) and Imja valley seen from the same photo point in 2007. Warming temperatures have contributed to the recession of more than a hundred metres of ice, seen to the left of Ama Dablam (the vertical black line farthest to the left in the old photo). The dramatic melting of glaciers and ice witnessed at lower altitudes is not yet seen at higher altitudes where the temperatures are much lower, and remain below zero even after warming. However, with continuing rising temperatures the temperatures may rise above zero and even the high altitude glaciers will become more susceptible, and liable to shrink.
