NASA space lasers map meltwater lakes in Antarctica with striking precision

(NASA/Goddard Space Flight Center) From above, the Antarctic Ice Sheet might look like a calm, perpetual ice blanket that has covered Antarctica for millions of years. But the ice sheet can be thousands of meters deep at its thickest, and it hides hundreds of meltwater lakes where its base meets the continent’s bedrock. Deep below the surface, some of these lakes fill and drain continuously through a system of waterways that eventually drain into the ocean.

Reducing the melting of the Greenland ice cap using solar geoengineering?

(University of Liege) Injecting sulphur into the stratosphere to reduce solar radiation and stop the Greenland ice cap from melting. An interesting scenario, but not without risks. Climatologists from the University of Liège (Belgium) have looked into the matter and have tested one of the scenarios put forward using the MAR climate model developed at ULiège. The results are mixed and have been published in the journal The Cryosphere.

Eruption of the Laacher See volcano redated

(Johannes Gutenberg Universitaet Mainz) The eruption of the Laacher See volcano in the Eifel in Germany is one of Central Europe’s largest eruptions over the past 100,000 years. Technical advances in combination with tree remains buried in the course of the eruption now enabled an international research team to accurately date the event. Accordingly, the eruption of the Laacher See volcano occurred 13,077 years ago and thus 126 years earlier than previously assumed.

Tipping elements can destabilize each other, leading to climate domino effects – EurekAlert

Interactions in the network can lower the critical temperature thresholds beyond which individual tipping elements begin destabilizing on the long-run, according to the study – the risk already increases significantly for warming of 1.5°C to 2°C, hence within the temperature…

Scientists now believe Antarctica is headed for a climate-change tipping point by 2060 – MarketWatch

While U.S. Secretary of State Antony Blinken draws attention to climate change in the Arctic at meetings with other national officials this week in Iceland, an even greater threat looms on the other side of the planet. New research shows it is Antarctica…

Fibre-optics used to take the temperature of Greenland Ice Sheet

(University of Cambridge) Scientists have used fibre-optic sensing to obtain the most detailed measurements of ice properties ever taken on the Greenland Ice Sheet. Their findings will be used to make more accurate models of the future movement of the world’s second-largest ice sheet, as the effects of climate change continue to accelerate.

Sea level rises from melting ice massively reduced by limiting global warming – Mirage News

Sea level rise caused by melting ice could be halved this century if the Paris Agreement target of limiting warming to 1.5°C is met. A new study, from an international research team including University of Leeds scientists, explored the land…
