In Patagonia, more snow could prevent glaciers from melting, but only if greenhouse gas emissions are quickly curbed.
Glacier front in southern Patagonia. Credit: Henning Åkesson In an era of declining glaciers, southern Patagonia has managed to retain an astonishing amount of ice. But a new study published in Scientific Reports by INSTAAR postdoctoral researcher Matthias Troch suggests that this protective effect may soon reach its limit. Before making their predictions, Troch and his collaborators looked back. They…

Measurements from ‘lost’ sea glider provide new insights into Antarctic ice melting
Gillian Damerel (former UEA) prepares to deploy the Sea Glider Merlin with the Ross Ice Shelf in the background. Credit: Walker Smith A new study reveals for the first time how rising sea temperatures have accelerated the melting of Antarctica’s major ice shelves over the past 40 years. Scientists at the University of East Anglia (UEA) say the study, which…

Earth experienced a period of massive and rapid melting after the last ice age, new research suggests
Credit: CC0 Public Domain At the end of the last global ice age, the frigid Earth reached a pre-built limit of climate change and melted into a slimy planet. The results of the Virginia Tech-led study show direct evidence of a slushy planet (also known as the “Plume World Ocean” era), when sky-high carbon dioxide concentrations sent the frozen Earth…

Melting Arctic sea ice could affect global ocean circulation, research warns
Melting sea ice can cause temperatures to drop. Credit: Karine Nigar Aarskog / UiT Norwegian Arctic University A warming climate in the polar regions could significantly disrupt ocean circulation patterns, a new study shows. Scientists have discovered that in the distant past, melting Arctic sea ice may have increased the flow of freshwater into the Nordic Seas, significantly impacting ocean…
