Why is the antarctic warming faster?

Answer 1

There are several reasons why the Arctic is warming faster than the Antarctic, in fact, faster than the rest of the world:

1. The albedo feedback. White snow and ice reflect the heat, so when they melt, the darker surfaces below absorb more heat.
2. The ocean is never colder than -2°C and when the sea ice melts warmth moves from the ocean into the atmosphere.
3. Global warming is likely to change the circulation patterns in the atmosphere and the oceans, causing more heat to be transferred to the Arctic.
4. The Antarctic is much colder than the Arctic. The coldest temperature in Antarctica is about -80°C, compared to -50°C in the Arctic. So the Arctic warms more easily than the Antarctic.

Answer 2

There are five reasons why the Arctic is warming faster than the rest of the world:

1. The albedo feedback. White snow and ice reflect the heat, so when they melt, the darker surfaces below absorb more heat.
2. Cold air holds less water, so radiation in the Arctic immediately heats the air, whereas in the tropics, radiation first has to evaporate the water vapour.
3. The colder Arctic means that the atmospheric layer is shallower than in the tropics. So the atmosphere warms up more quickly and warms the near surface air more quickly.
4. The ocean is never colder than -2°C and when the sea ice melts warmth moves from the ocean into the atmosphere.
5. Global warming is likely to change the circulation patterns in the atmosphere and the oceans, causing more heat to be transferred to the Arctic.

Answer 3

The Southern Polar region on Earth is anchored by a continent -- Antarctica, which contains about 90% of the Earth's store of ice. The Northern Polar region is simply covered with sea ice, which is not as cold as the continental ice sheet that covers 98% of Antarctica. Antarctica covers about 10% of the Earth's surface.

Antarctica is about 30 degrees F colder than the Arctic.

Answer 4

New science published after the IPCC report has shown how global warming is happening faster than anticipated. Sea-level rise may be accelerating, Arctic sea ice is rapidly melting, and forests are being transformed.The reason of all is polution is increased fastly.

Answer 5

The Arctic Ocean is sea ice surrounded by land. Antarctica is a continent surrounded by the Southern Ocean. Antarctica is about 30 degrees F colder than the Arctic, and is sometimes called the Earth's 'heat sink'. The continent is covered with an ice sheet that contains about 90% of the Earth's store of ice.

Answer 6

Antarctica is a continent and the Arctic is open water, which freezes over. Antarctica is about 30 degrees F colder than the Arctic, because the ice sheet that covers 98% of Antarctica holds about 90% of the earth's store of ice.

Answer 7

Antarctica is colder than the Arctic for two reasons. First, much of the continent is more than 3 kilometres (2 mi) above sea level, and temperature decreases with elevation. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. -Olgierd Nowakoski
