Greenland

By Emmanuella Anokam For African journalists and experts on tour of Gazprom’s production facilities in Russia, from July 17 to 26, nothing could be more fascinating than crossing the Arctic Circle in the Yamal Peninsula. Speaking in an interview, some of the journalists said they had known the Arctic Circle…

This article is part of TPM Cafe, TPM’s home for opinion and news analysis. It was originally published at The Conversation. About 400,000 years ago, large parts of Greenland were ice-free. Scrubby tundra basked in the Sun’s rays on the island’s northwest highlands. Evidence suggests that a forest of spruce trees, buzzing…

The varying extent of ice sheets has so far been inadequately represented in conventional climate models. Credit: Max Planck Institute for Meteorology In recent decades the ice sheets of Greenland and Antarctica have decreased dramatically, and scientific projections suggest an increasing retreat in the future. Ice sheets form on land…

Greenland’s ice sheet contains enough water to raise sea levels by several metres NASA A sediment core from underneath the Greenland ice sheet has provided the first direct evidence that much of the ice disappeared during an interglacial period 400,000 years ago, when global temperatures were similar to what they are…

In 1959, the United States began construction of a real-life version of the frozen Echo Base from The Empire Strikes Back. The plan for Camp Century was to test snow tunneling technologies in northwest Greenland, not far from the north pole, ostensibly for scientific research. Really, the US was flexing…

A cruise ship originating from Greenland has made a stop in Churchill — something the northern Manitoba town’s mayor says hasn’t happened in well over a decade. Michael Spence told 680 CJOB’s The Start that the arrival of the Silver Endeavour, a 10-deck luxury polar cruise ship with a 200-passenger…

During the last ice age, massive icebergs periodically broke off from an ice sheet covering a large swath of North America and discharged rapidly melting ice into the North Atlantic Ocean around Greenland, triggering abrupt climate change impacts across the globe. These sudden episodes, called Heinrich events, occurred between 16,000…
