U.S. and British government researchers announced on Friday that climate change is quickly shrinking one Antarctic ice shelf, while another is disappearing and glaciers are melting faster than climate scientists originally predicted, Reuters reported. Scientists noted that the Wordie Ice Shelf, which has been disintegrating since the 1960s, is gone and the northern part of the Larsen Ice Shelf no longer exists. Since 1986, over 3,200 square miles have broken off from the Larsen shelf. U.S....

According to the UN Environmental Program, an enormous breakaway piece of Antarctica's ice shelf could amplify the already significant effects of global warming in the region. The 40-kilometer (25-mile) ice bridge "“ which was the Wilkins Ice Shelf's last bridge to the coast "“ has now completely broken off and can be seen in satellite images as a free-floating island of ice roughly the size of Jamaica. Before it starting melting in the early 1990's, Wilkins Ice Shelf had an area...

Experts reported on Friday that the amount of sea ice around Antarctica has grown in recent Septembers in what could be an unusual side-effect of global warming. Since the late 1970s, in the southern hemisphere winter, when emperor penguins huddle together against the biting cold, ice on the sea around Antarctica has been increasing, perhaps because climate change means shifts in winds, sea currents or snowfall. But Arctic sea ice at the other end of the planet is now close to matching a...

Four years of scientific research on ice core data has brought to light the warming trend in West Antarctica, the world's coldest climate.  According to the study, the West Antarctic warmed in response to higher temperatures in the tropical Pacific, which itself has been warming due to weather patterns including an El Nino event from 1939 to 1942 and greenhouse emissions from cars and factories. "An increasingly large part of the signal is becoming due to human activity," said the...

New evidence could solve the puzzle of why Antarctica went into the deep freeze A team of scientists from Cardiff University's School of Earth and Ocean Sciences and Amgueddfa Cymru - National Museum Wales travelled to Africa to find new evidence of climate change which helps explain some of the mystery surrounding the appearance of the Antarctic ice sheet. Ice sheet formation in the Antarctic is one of the most important climatic shifts in Earth's history. However, previous temperature...

On the world's coldest continent of Antarctica, the landscape is so vast and varied that only satellites can fully capture the extent of changes in the snow melting across its valleys, mountains, glaciers and ice shelves. In a new NASA study, researchers using 20 years of data from space-based sensors have confirmed that Antarctic snow is melting farther inland from the coast over time, melting at higher altitudes than ever and increasingly melting on Antarctica's largest ice shelf. With a...

WASHINGTON (AP) - The air over Antarctica is warming even faster than in other parts of the world, according to an analysis of 30 years of weather balloon data. While surface warming has been reported in parts of Antarctica, this is the first report of broad-scale climate change across the whole continent, the British Antarctic Survey says in Friday's issue of the journal Science. The weather balloon data show a warming of 0.9 degree to 1.3 degree Fahrenheit per decade over the last 30...

New results shed light on how Antarctica became the icy, barren continent that we know today. British Antarctic Survey (BAS) scientists have discovered that 30-50 million years ago, South America and Antarctica split apart very rapidly. This formed the Drake Passage and resulted in a major global cooling. The findings are published in the latest issue of Earth and Planetary Science Letters. Lead Author Dr Roy Livermore says 'we deciphered the remarkable 'herringbone' pattern of ridges that...
