Okeyyy~~~let me re-explain the meaning of global warming~~~
Global warming is the increase in the average measured temperature of the Earth's near-surface air and oceans since the mid-twentieth century, and its projected continuation.
Due to the global warming,the sea absorbs heat from the sun, while the ice largely reflects the sun rays back to space. Thus, retreating sea ice will allow the sun to warm the now exposed sea water, contributing to further warming. The mechanism is the same as when a black car heats up faster in sunlight than a white car. This albedo change is also the main reason why IPCC predict polar temperatures in the northern hemisphere to rise up to twice as much as those of the rest of the world. In September 2007, the Arctic sea ice area reached about half the size of the average summer minimum area between 1979 to 2000. Based on the accelerated loss, predictions are that by 2030 the Arctic could be ice-free part of the year.Also in September 2007, Arctic sea ice retreated far enough for the Northwest Passage to become navigable to shipping for the first time in recorded history.The polar amplification of global warming is not predicted to occur in the southern hemisphere.The Antarctic sea ice reached its greatest extent on record since the beginning of observation in 1979,but the gain in ice in the south is exceeded by the loss in the north. The trend for global sea ice, northern hemisphere and southern hemisphere combined is clearly a decline.
This cause the iceberg to melt~~~my area of global warming is melting of iceberg~~~hehe
