"An ice sheet is a mass of glacier ice that covers surrounding terrain and is greater than 50,000 km² 20,000 mile² thus also known as continental glacier. The only current ice sheets are in Antarctica and Greenland. Ice sheets are bigger than ice shelves or alpine glaciers. Masses of ice covering less than 50,000 km2 are termed an ice cap. An ice cap will typically feed a series of glaciers. The Greenland, and probably the Antarctic, ice sheets have been losing mass recently. However, loss of mass on the Antarctic sheet may continue, if there is sufficient loss to outlet glaciers. By today's recent observations the vulnerability of the ice sheets to warming could increase future sea level rise. But our understanding of these processes is still very limited and there is no consensus on their magnitude. More research work is therefore required in order to improve the reliability of predictions of ice-sheet response on global warming. According to a study at the University of Minnesota. Robert Johnson, an adjunct professor of geology and geophysics Global warming may actually assist new ice sheet growth because growth depends less on cold temperatures than on a strong supply of moisture and very heavy snowfall over northern land masses. He published his arguments in a book, Secrets of the Ice Ages.

Photo of a ice cap at the IJsselmeer (IJmeer) near Amsterdam. The lake is frozen and fresh snow fallen recently. I feel like Roald Amundsen on one of his Polar treks to the North pole. The sounds of fresh snow rustle under my shoes and a little Cessna airplane just flying over. Must have been an exciting flight for them over this beautiful ice sheet. In the distance you can see the lighthouse of Marken. The ice is a bit unsafe to walk the 10km. The is the Marken lighthouse, given its name due to its shape ('paard' means 'horse' in dutch). The original was built in 1700, then reconstructed on top of the early foundations in 1839. It's still in use today."
