Most detailed ever study of Greenland ice sheet warns of irreversible ice loss — ScienceDaily

In a study published this week in The Cryosphere, researchers from the National Centre for Atmospheric Science and University of Reading demonstrate how climate change could lead to irreversible sea level rise as temperatures continue to rise and the Greenland ice sheet continues to decline.

The massive ice sheet faces a point of no return, beyond which it will no longer fully regrow, permanently changing sea levels around the world.

The Greenland ice sheet is seven times the area of the UK, and stores a large amount of the Earth’s frozen water. At current rates of melting, it contributes almost 1mm to sea level per year, and accounts for around a quarter of total sea level rise.

Since 2003, despite seasonal periods of growth, Greenland’s ice sheet has lost three and a half trillion tonnes of ice.

Rising sea levels are one of the most severe effects of climate

UPDATE 4-Chinese smartphone maker Xiaomi raises $3.9 bln in equity deal – term sheet

* Deal is largest of its kind in Hong Kong to date

* Indicative price set at HK$23.70, lower end of range

* Convertible bond deal to raise $855 mln (Adds deal detail)

HONG KONG, Dec 2 (Reuters) – Chinese smartphone maker Xiaomi Corp has raised $3.91 billion as part of a deal that includes Hong Kong’s largest top-up placement, according to a term sheet seen by Reuters.

Potential investors have been told the price should be HK$23.70 for the 1 billion shares that are being sold down in the deal, the term sheet showed.

The price is at the lower end of the range flagged by the company on Tuesday when it said the deal would be between HK$23.70 and HK$24.50.

At HK$23.70, the placement would raise $3.06 billion.

A convertible bond deal to raise $855 million was also finalised Wednesday, according to the term sheet, to take Xiaomi’s

Changes in the Antarctic ice sheet were driven by the melting ice sheets in the Northern Hemisphere — ScienceDaily

Over the past 40,000 years, ice sheets thousands of kilometres apart have influenced one another through sea level changes, according to research published today in Nature. New modelling of ice sheet changes during the most recent glacial cycle by a McGill-led team offers a clearer idea of the mechanisms that drive change than had previously existed and explains newly available geological records. The study demonstrates, for the first time, that during this period, changes in the Antarctic ice sheet were driven by the melting ice sheets in the Northern Hemisphere.

As the climate cooled, during the last Ice Age, water became locked up in land ice in the Northern Hemisphere leading to dropping sea levels in Antarctica and consequent growth of the ice sheet. As the climate warmed, on the other hand, as it did through the period of deglaciation, the retreating ice in the Northern Hemisphere led to

Models suggest subglacial river flows entire length of Greenland’s ice sheet

Nov. 12 (UPI) — New analysis suggests a valley stretching the length of Greenland’s ice sheet might allow meltwater from the continent’s interior to flow hundreds of miles toward an outlet at Petermann Fjord, positioned on the island’s northern coast.

For years, scientists have been working hard to map the contours of Greenland’s bedrock, which lies beneath thousands of feet of ice.

“It is an extremely hard to observe environment,” Chris Chambers, researcher at Hokkaido University’s Institute of Low Temperature Science, told UPI in an email.

Over the years, scientists have built a relatively detailed map of the continent’s bedrock — and the shape of the ice sheet’s underbelly — by piecing together radar scans captured research aircraft.

Unfortunately, the process of stitching together dozens of radar scans leaves lots of small gaps in the data. Researchers typically rely on mathematical models to fill these gaps.

“The data gaps are

Possible 1,000-kilometer-long river running deep below Greenland’s ice sheet — ScienceDaily

Computational models suggest that melting water originating in the deep interior of Greenland could flow the entire length of a subglacial valley and exit at Petermann Fjord, along the northern coast of the island. Updating ice sheet models with this open valley could provide additional insight for future climate change predictions.

Radar surveys have previously mapped Greenland’s bedrock buried beneath two to three thousand meters of ice. Mathematical models were used to fill in the gaps in survey data and infer bedrock depths. The surveys revealed the long valley, but suggested it was segmented, preventing water from flowing freely through it. However, the peaks breaking the valley into segments only show up in areas where the mathematical modelling was used to fill in missing data, so could not be real.

Christopher Chambers and Ralf Greve, scientists at Hokkaido University’s Institute of Low Temperature Science, wanted to explore what might happen
