Antarctic surface ice layer temperature trends between 1981 and 2007, based on thermal infrared observations made by a series of NOAA satellite sensors.. Climate change caused by greenhouse gas emissions from human activities occurs everywhere on Earth, and while Antarctica is less vulnerable to it than any other continent, [1] climate change in Antarctica has been observed.
The climate of Antarctica is the coldest on Earth. The continent is also extremely dry (it is a desert [ 1 ] ), averaging 166 mm (6.5 in) of precipitation per year. Snow rarely melts on most parts of the continent, and, after being compressed, becomes the glacier ice that makes up the ice sheet .
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).
The southernmost continent is not isolated from the extreme weather associated with human-caused climate change, according to a new paper in Frontiers in Environmental Science that tries to make a ...
Climate change caused by greenhouse gas emissions from human activities occurs everywhere on Earth, and while Antarctica is less vulnerable to it than any other continent, [79] climate change in Antarctica has been observed.
Evidence from a 2,000-foot-long ice core shows rapid past melting — a stark warning for potential sea level rise as temperatures soar
500 million years of climate change Ice core data for the past 400,000 years, with the present at right. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO 2, and red curve is windblown glacial dust (loess).
Students and researchers from UW-Madison and Madison Area Technical College help oversee a large portion of Antarctica's weather stations. How a Wisconsin team works the front lines of Antarctic ...
