A groundbreaking study published in Science China Earth Sciences has unveiled a stunning reversal in the fortunes of the Antarctic Ice Sheet (AIS), which gained mass at an unprecedented rate between 2021 and 2023...

The Copenhagen scientists examined hundreds of old aerial photographs taken for mapping work in 1937. The images were supplemented with a number of photographs taken in the 1950s and 1974 of the same area and a 3D computer...

The paper clarifies and improves calculations of the role of viscous dissipation of kinetic energy into thermal energy as this physical process appears in models of meltwater flows embedded in and at the boundaries of glaciers...

...the heatwave only raised temperatures to (minus) -11.8°C maintaining deadly cold temperatures.

During this period, the mass gain over the East AIS and Antarctic Peninsula was unprecedented within the past two decades

Large variations from year to year often occur, and they are usually the result of wind patterns, which either blow away from the continent, thus pushing ice outwards, or towards it.

If true, these seasonal signatures may be uncaptured in some measurements of Antarctic ice-mass loss, with potentially important implications for global sea-level rise estimates

Peer-Reviewed Publication UNIVERSITY OF CAMBRIDGE Despite the rapid melting of ice in many parts of Antarctica during the second half of the 20th century, researchers have found that the floating ice…

“This lake is likely to have a record of the entire history of the East Antarctic Ice Sheet, its initiation over 34 million years ago, as well as its growth and evolution across glacial cycles since then

“This study demonstrates clearly that the impact of 21st-century climate change on the Antarctic ice sheet extends well beyond the 21st century itself, and the most severe consequences — multi-meter contribution to sea-level...

More ice of course only forms when the temperature drops. Global warming has yet to reach the South Pole. This is one of the most inconvenient regions on the planet for the global warming alarmists.

Using modern methods to calculate projected changes to sea levels, researchers discovered that the two ice sheets of Greenland and Antarctica respond differently, reflecting their very distinct local climates.

He added: "The possibility of Pine Island Glacier entering an unstable retreat has been raised before but this is the first time that this possibility is rigorously established and quantified.

But observations show that ice extent in the Arctic has shrunk faster than models predicted, and in the Antarctic it has been growing slightly. Researchers are looking much closer at Antarctica, saying, “Wait, what is going...
