How is Antarctica bucking the global warming trend?

These days, any debate between climate “Alarmists” and “Deniers” has a path that touches Antarctica and its trend-defying cooling. The continent’s unique geography and weather phenomena, the key factors behind its “negative greenhouse effect,” need more public space to counter the arguments by climate change skeptics.

Antarctica, technically a desert at an elevation of 2300 meters, is scarce of atmospheric moisture, which is also a greenhouse gas that traps heat from the Earth’s surface contributing to the warming effect, writes Science. The absence of vapors in the continent’s atmosphere lets the heat pass into space and hence the cooling effect.

Besides, another weather phenomenon, called temperature inversion, by virtue of which the temperature rises with altitude, also leads to the chilling of Antarctica, reports Live Science.
