Antarctica is the coldest, driest continent on Earth, and has the highest average elevation. [1] Antarctica's dryness means the air contains little water vapor and conducts heat poorly. [26] The Southern Ocean surrounding the continent is far more effective at absorbing heat than any other ocean. [27]
Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. If all the land-ice covering Antarctica were to melt—around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice—the seas would rise by over 60 m (200 ft). [22]
Record of atmospheric temperature taken from EPICA ice core in Antarctica. The Antarctic Cold Reversal (ACR) was a climatic event of intense atmospheric and oceanic cooling across the southern hemisphere (>40°S) between 14,700 and 13,000 years before present that interrupted the most recent deglacial climate warming (c. 18,000-11,500 years BP).
But the benefits of cold plunge therapy (the more official name) go beyond a yearly dip in the frigid ocean. In fact, the practice has many practical claims, including faster recover.
For me, the polar plunge served as a teaching moment. I nearly missed out on what may have been a once-in-a-lifetime opportunity because I was afraid. But in the end, it was fun and even freeing.
East Antarctica is colder than its western counterpart because of its higher elevation. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry, with moderate wind speeds. Heavy snowfalls are common on the coastal portion of Antarctica, where snowfalls of up to 1.22 m (48 in) in 48 hours have been recorded.
The hottest wellness trend is all about getting really, really cold. Here, experts explain why cold plunge, also called cold water immersion therapy, is key for your health and wellness. 14 ...
Antarctica is the largest ice desert in the world. Some 98% of Antarctica is covered by the Antarctic ice sheet , the world's largest ice sheet and also its largest reservoir of fresh water . Averaging at least 1.6 km thick, the ice is so massive that it has depressed the continental bedrock in some areas more than 2.5 km below sea level ...
