How has global warming affected life in antaratica?

Answer 1

Global warming is causing the ice packs to melt, which then has water runoff that flows over the ice packs melting the surface and into the ocean and melting the bottom of the ice as well. This in turn causes the packs to melt faster.

The decrease in size of the ice packs decreases the surface that reflects the sun's rays, which are then absorbed into the ocean more and on tundra surfaces. Thus heating up the earth more.

All the above causes a cycle of melting and heating which now cannot be stopped.

A:Global warming is a phenomenon whereby the earth's average temperature increases. There are a couple ways that the earth's temperature is measured. The atmospheric temperature is what most people refer to when they discuss global warming. There is also tertiary temperature, which is the temperature of the land itself. The earth has experienced periods of global warming in the past.

In simple terms, a rise in temperature would cause any frozen water to begin melting, which is how the polar ice caps would be affected. However, due to the result of extreme weather also caused by global warming, it isn't immediately clear if global warming will cause a complete melting of the ice caps. For example, global warming causes more extreme temperature fluctuations so, while one year the ice caps shrink to record lows, the next year that might expand again. Also, it's been observed that when the north pole ice cap melts, the south pole ice cap expands. Scientists are still studying global warming effects, and have not reached a consensus about what will happen in the future.

The only thing for certain is that the ice caps fluctuate much more than in the past due to extreme weather and temperature fluctuations.

Changing wind patterns also causes the ice caps to melt. As they melt, the moving water corrodes at the remaining ice, speeding up the process.

Answer 2

They are melting!

In Greenland scientists are afraid there is a layer of water, melted ice, under the glaciers which is helping them move more quickly into the warming seas.

In West Antarctica the glaciers go right down into the sea and rest on the rocky bottom. The warming oceans are melting these underneath, leaving ice shelves. These shelves are breaking off, in chunks sometimes as big as Manhattan Island.

Answer 3

Global warming has destroyed natural habitats of polar bears. It has also caused ice glaciers.
