Less sea ice means the planet cannot reflect the suns rays and cool itself. Warmer seas and oceans absorb more of the sun’s heat, which in turn melts more ice. The loss of sea ice is a self-perpetuating recipe for climate disaster.

When sea ice retreats and permafrost degrades, coastlines become much more vulnerable to erosion. These pictures were taken in Shishmaref, Alaska, during a storm in 2003. Only two hours separate the first photo from the second. For reference, red arrows mark the barrel. By the time the second photograph was taken, the coastline in the ...

Image 2: Picture of a glacier. Most of the park is on the Inland Ice, the great, two-mile-thick ice sheet that covers most of the island of Greenland, and one that could raise global sea levels about 23 feet (7 m) if melted. However, some of the park includes spectacular coastal mountains and the rich adjacent seas.

Getting salt from sea water. Seawater is salty because it has dissolved salty solids that come from active volcanoes on the floors of the oceans. One way to recover the salt is through . evaporation. Some hot countries build a low wall around a shallow section of the sea. This traps the …

The sea ice softens and begins to melt in the summer sun, large pieces of ice break off from the edge, and more and more of the sea is uncovered. The ice algae are released and drift down to the ocean floor where other animals eat it.

During an Ice Age, glaciers begin to spread away from the polar regions of Earth. This happens when the accumulation of ice and snow is greater than the amount that melts each year. Look at the pictures at the bottom of the Pleistocene page, which compares the ice extent between the peak of the last ice age (about 18,000 years ago) with the ...

2. sea levels have risen. 3. the amount of time that snow covers our earth has gone down. 4. glaciers and Arctic ice (Ice that covers the ocean around the North Pole) are becoming depleted. 4. Say: Why would sea levels rising indicate global warming? Water stored in Glaciers and Sea Ice melts and goes into the ocean. This makes the ocean level ...

The sea ice creates habitat for the algae, phytoplankton, krill, ice fish, seals, and penguins. Why are there seasonal differences in the extent of the Antarctic sea ice? Antarctica experiences extremely cold temperatures during its sunless winters, consequently freezing more ocean area.
