What is underneath Antarctica ice?
The discovery of what appear to be sponges in the pitch-black seawater beneath almost half a mile of ice has biologists baffled.

Is Antarctica dangerous to visit?
Is it dangerous? While of course no travel, especially travel by boat to somewhere remote, is entirely without risk, Antarctic travel is not especially dangerous. If you go from South America, the most dangerous part is the open ocean between the Cape Horn and the Antarctic Peninsula known as Drake’s Passage.
Will Antarctica melt?
Antarctica is already losing more than 200 billion tons of ice each year. But scientists suspect that surface melting may cause greater losses in the future as the ice sheet continues to warm. For now, scientists don’t think that atmospheric rivers are actually causing that much mass loss in Antarctica.
Did Antarctica ever have trees?
In a small part of Alexander Island, on the west coast of the Antarctic Peninsula, ancient fossil trees that date back 100 million years can be found, with logs up to seven metres high (23 feet) still found standing upright. The roots of these coniferous trees are still attached to the carbonaceous soil deposits today.

Why are dogs banned in Antarctica?
Sled dogs were used until 1992, when they were banned from Antarctica by the Protocol on Environmental Protection to the Antarctic Treaty over concerns that the dogs might transfer diseases such as canine distemper to the seal population. The dogs were used to working on snow, not on ice, in much milder temperatures.

Antarctica is not a country: it has no government and no indigenous population. Instead, the entire continent is set aside as a scientific preserve. The Antarctic Treaty, which came into force in 1961, enshrines an ideal of intellectual exchange. Military activity is banned, as is prospecting for minerals.

The Cretaceous, 145m to 66m years ago, was a warm period during which Earth had a greenhouse climate and vegetation grew in Antarctica. Scientists say the new discovery not only reveals that swampy rainforests were thriving near the south pole about 90m years ago but that temperatures were higher than expected.
