Permafrost

As tourists flock to Greenland to take in its breathtaking icebergs and natural beauty, authorities are mulling ways to control crowds to protect the fragile environment, already threatened by global warming.

Lightning strikes inside the Arctic circle may double this century, sparking widespread tundra fires and increasing the risk of setting off the carbon time bomb held within permafrost, new research showed on April 5.

A well-preserved Ice Age woolly rhino with many of its internal organs still intact has been recovered from permafrost in Russia's extreme north.

Russian media reported on Dec. 30 that the carcass was revealed by melting permafrost in Yakutia in August. Scientists are waiting for ice roads in the Arctic region to become passable to deliver it to a lab for studies next month.

Last month was the hottest May on record worldwide, a European climate agency has reported, with temperatures in Siberia rising 10 degrees Celsius (18 degrees Fahrenheit) above their normal levels.

Greenland's largest airport will be closed due to climate change. The airport north of the capital Nuuk serves 11,000 aircraft annually and serves as a base for travel across the vast island.

The reason for the closure is the melting of the permafrost. The ever-frozen ground on which the airport was built began to melt from the higher temperatures. This causes cracks.

The oceans, which are the source of life on Earth, could become our worst enemy globally, if nothing is done to significantly reduce greenhouse gas emissions. This is said in a UN report, BTA reported.

A chunk of hard ice north of Greenland has disappeared.

Independent - In a summer marked by global heatwaves, wildfires and drought, scientists have warned that things could get considerably worse under a future scenario dubbed "hothouse Earth".

Pipes are built over bulging and unstable Arctic pingos prone to violent eruptions caused by 'thawing methane gas', as seen twice on the Yamal peninsula this year.

Scientists recently made a startling discovery whilst on an expedition to monitor permafrost on the Gydan Peninsula; a 1,000-year-old bronze cup from ancient Persia (modern day Iran). The discovery was made close to the Kara Sea, the furthest north such an artifact has been found.

The cup was likely brought to the region by ancient traders seeking walrus tusks, birds, and fur.
