An 11-year comparison of Marion and Prince Edward Islands indicate the disappearing ice cap. A SPOT-2 false colour composite satellite image, acquired in May 1998, and an EO-1 ALI image, acquired in May 2009, demonstrate the changes in snow cover within an 11-year period. The disappearance of the ice cap at these islands is astounding – this is visible evidence of the consequences of climate change. Studies conducted at the islands have indicated that between 1948 and 2009, about 42-million cubic meters of ice melted from the mountain top. Furthermore, the ice continues to melt at a rate of between 1 to 1.5m every year.
