Melting Ice Caps

Melting of Ice Caps *Many reports say that Polar ice caps in Greenland and Antarctica are melting much faster then what scientists expected, but are larger. *Since 1995, ice shelf 's area has shrunk by 40%(Southern Polar)*If the entire Northern Polar sheet melted sea levels would rise by 60 meters.* Therefore as the ice caps melt the higher our water levels become. Why it is Melting?- Rising of global temperatures speeds the melting of glaciers and ice caps. -Due to summer warming's the ice caps are thinning.-When we burn fossil fuels like oil, coal, gas to generate electricity and power our cars, we make heat-trapping gases that cause global warming.Consequences of Melting Ice Caps *All around the world there is evidence of melting ice caps because we see a rise in sea levels from melting ice shields.* Countries with low elevations are shrinking because of the rising sea levels, for example the island nation the Maldives might be completely covered by water by the end of the century and global sea levels could rise as much as 16 inches over the next century. *Coastal wetlands and barrier islands will be threatened by rising sea levels, for example the Gulf of Mexico. * A greater risk of flooding in Coastal communities. *People living in Coastal populated areas may have to move to high ground or inland.

Life on Ice Caps!*Not a lot of life can sustain on ice caps...but mammals as large as Musk Ox and Polar bears can.-Marine ecosystems under the ice caps can have lots of biodiversity, like seaweed, krill, fish, and marine mammals like seals and whales. -Many Indigenous people have adapted to a new way of life because of the melting ice caps.-The Yupik people take advantage of the seasonal thawing of ice caps to harvest plants and berries and marine life for food, and material goods.

Ice Cap- covering of ice or over a large area, especially on the polar regions of the Earth.

What is it?* An ice cap is a glacier or thick layer of ice and snow that covers less than 50 000 km of land area (highland area). *An interconnected series of ice caps and glaciers is called an ice field and Nunataks; are areas where just the summits of mountains penetrate the ice.*Large mass of ice

Polar Ice Caps Locations!-Ice fields and ice caps exist all over the world. A big area of is called polar ice caps. They're mostly in high latitude regions like the North Pole. -Northern Europe is home to many ice caps. Vatnajokull, Iceland is an ice cap that covers more than 8% of the island nation; the largest ice cap is the Severny island ice cap in the Russian Arctic.- Mountain ranges such as the Himalayans, Rockies, Andes and Southern Alps of New Zealand are all examples of many ice caps and ice fields. - Mountain ranges are covered in ice caps and ice fields. Mount. Kilimanjaro, Tanzania, (the tallest mount. in Africa) used to have large ice caps on its summit, but for the past few decades it has been shrinking due to global warming.

Facts!-Norway has the largest of many ice caps in Scandinavia-The largest ice fields in Canada are found in the Arctic Archipelago-Icefields average thickness is less than 100-150 m and the thickest ice is 365 m thick.
