Explanation:
- Its true that most of the arctic and the Antarctic ice sheets have melted and the earth surges steadily towards the dangerous wrath of the planet, various reports have given proof that the arctic ice or that of the north pole melting fast at an alarming rate as the altitudinal conditions and the impacts of the climate changes are more profound in this region.
- With the rise of temperature of more than 1.8° F, in the past decades, the temperature of this region the current rate of the greenhouse emission has destroyed about 90% of the ice that is left. And is projected to a 3.7° F rise as the threshold of the impact of man activities.
- <u>Antarctica, on the other hand, is not fast as arctic but thew studies have shown that is somewhat similar to average global warming. The antarctic absorbing up the heat from the southern ocean water bodies. Also in the past years, the invasion of species and the uneven cooling has led to 2 °C warming of the continent.</u>
