The weather in Antarctica can be highly variable, and the weather conditions can often change dramatically in short periods of time. There are various classifications for describing weather conditions in Antarctica; restrictions given to workers during the different conditions vary by station and nation. [19] [20] [21]
Aerial photograph of Vostok Station, the coldest directly observed location on Earth. The location of Vostok Station in Antarctica. The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C (−128.6 °F; 184.0 K) at the then-Soviet Vostok Station in Antarctica on 21 July 1983 by ground measurements.
A record-breaking heat wave unfolding at what should be the coldest time in Earth’s coldest place has scientists concerned about what it could mean for the future health of the Antarctic ...
The loss of this ice sheet would take between 2,000 and 13,000 years, [21] [22] although several centuries of high greenhouse emissions could shorten this time to 500 years. [23] A sea-level rise of 3.3 m (10 ft 10 in) would occur if the ice sheet collapses, leaving ice caps on the mountains, and 4.3 m (14 ft 1 in) if those ice caps also melt. [24]
The climate of present-day Antarctica does not allow extensive vegetation to form. [127] A combination of freezing temperatures, poor soil quality, and a lack of moisture and sunlight inhibit plant growth, causing low species diversity and limited distribution. The flora largely consists of bryophytes (25 species of liverworts and 100 species ...
With detailed weather station and satellite data dating back only about 40 years, scientists wondered whether these events meant Antarctica had reached a tipping point, or a point of accelerated ...
Parts of icy Antarctica are turning green with plant life as the region is gripped by extreme heat events, new research shows, sparking concerns about the changing landscape on this vast continent.
The current flows at a rate of about 4 km/h (2.5 mph) over the Macquarie Ridge south of New Zealand. [6] The ACC varies with time. Evidence of this is the Antarctic Circumpolar Wave, a periodic oscillation that affects the climate of much of the southern hemisphere. [7]
