5.0 04 When the atmosphere had much higher levels of carbon dioxide, Antarctica was as warm as California. New research has revealed that 430 million to 50 million years ago, temperatures on the frozen continent averaged 57 degrees Fahrenheit, with part of the surrounding Pacific Ocean reaching up to 72 degrees. In this ancient era, known as the Eocene epoch, […]

5.0 01 European researchers have once again warned that the thinning of the Antarctic ice shelf means that the flow of glaciers on the frozen continent could accelerate, with a consequent rise in sea levels. They examine, in two separate studies, the increasingly precarious state of some of the ice shelf. When the shelf, consisting of ice floating on the […]

4.0 04 While restoring one of the exploration huts in Antarctica, Conservators of the New Zealand Antarctic Heritage Trust discovered a 100 year old box that turned out to be a remarkable treasure. It contained 22 never-before-seen cellulose nitrate negatives documenting the life of Antarctic explorers a 100 years back. Preserved in a block of ice, this 100 year old box of […]

3.9 21 Winter in Antarctica, it is dark all of the time. In the Antarctic summer, (between January and March, when there is plenty of daylight—twenty-four hours a day! In September, the Sun rises, and then doesn’t set again until March. Why does Antarctica have six whole months of darkness in the winter and six whole months of lightness in […]

5.0 02 According to a new study by Nasa, Antarctica’s Larsen B ice-shelf is on course to completely disintegrate within the next five years. Studies show that the 10,000-year-old ice shelf, after partially collapsing in 2002, is “quickly weakening.” “These are warning signs that the remnant is disintegrating,” said Ala Khazendar of Nasa’s Jet Propulsion Laboratory (JPL) in Pasadena, California.

3.5 02 Buried deep in the Antarctic ice, an observatory has spotted ghostly, nearly massless particles coming from inside our galaxy and points beyond the Milky Way. Finding these cosmic neutrinos not only confirms their existence but also sheds light on the origins of cosmic rays, the researchers said. The IceCube Neutrino Observatory is made up of 86 shafts dug […]

5.0 01 In 2016, the world’s 2nd largest emperor penguin colony had been wiped out overnight. Thousands of emperor penguin chicks drowned after an ice shelf in Antarctica collapsed. In the years following the catastrophic collapse of the ice shelf at Halley Bay, Scientists have concluded that no breeding has been detected in the area since. On average, approximately 15,000 […]

5.0 04 The warming of the world’s oceans is penetrating radar. They discovered two causing a glacier the size of California in massive undersea valleys beneath the East Antarctica to melt, and scientists fear ice sheet, one of which is 3 miles wide, its collapse could eventually cause global Those canyons allow warm, salty water sea levels to rise by […]

5.0 02 Soil frost is a nearly universal process in the Arctic. In a recent dissertation by doctoral student Marina Becher at Umeå University, it is shown that the frequency and extent of Arctic soil frost is important for the release of the greenhouse gas carbon dioxide from arctic soil. Soil in the Arctic has for thousands of years gathered […]

5.0 01 Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear […]
