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.
A portion of the world's iciest, coldest continent is "greening" at a dramatic rate because of global warming, scientists announced in a recent study. In fact, the research showed that vegetation ...
The frozen continent of Antarctica was the last continent humanity set foot on. The first documented landings made below the Antarctic Circle took place in 1820, when Admiral Fabian Gottlieb von Bellingshausen and the crew of the Vostok and Mirny, as part of the Russian Antarctic Expedition, made land at Peter I Island and Alexander Island.
Eastern Antarctica is to the right of the Transantarctic Mountains and Western Antarctica is to the left. Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle (one of the five major circles of latitude that mark maps of the world), Antarctica is surrounded by the Southern Ocean.
As of today, there have been 138 possible volcanoes identified in West Antarctica. [3] There is limited knowledge about West Antarctic Volcanoes due to the presence of the West Antarctic Ice Sheet, which heavily covers the West Antarctic Rift System—a likely hub for volcanic activity. [4]
These lakes could threaten the future stability of parts of the Antarctic ice sheet.
Soils in Antarctica are nearly two-dimensional habitats, with most biological activity limited to the top four or five inches by the permanently frozen ground below. [4] Environments can be limiting due to soil properties such as unfavorable mineralogy, texture, structure, salts, pH, or moisture relationships. [5]
Two temperature records were set on February 6, one in each hemisphere, one for warmth, the other for mind-numbing cold. On Feb. 6, 2020, five years ago, Antarctica set its all-time record high of ...
