The Hunga Tonga eruption continues to have an impact on weather patterns

By Christoph Ruhsam Climate Change, Cryosphere & Climate

GOES-17 visible-band snapshot of the Hunga Tonga–Hunga Ha'apai eruption on 15 Jan 2022 (04:30 UTC). The key point: the plume rose unusually high into the stratosphere, helping loft water vapour that can influence climate for years.JTNDaWZyYW1lJTIwc3JjJTNEJTIyaHR0cHMlM0ElMkYlMkZ3d3cuZ29vZ2xlLmNvbSUyRm1hcHMlMkZlbWJlZCUzRnBiJTNEJTIxMW0xOCUyMTFtMTIlMjExbTMlMjExZDE4NDUyNTc3LjE2OTk5NTclMjEyZDE3Mi41ODg1NzgzMTM0MTYyNCUyMTNkLTE5LjEyMzkxNTUxMzA3MDcyNCUyMTJtMyUyMTFmMCUyMTJmMCUyMTNmMCUyMTNtMiUyMTFpMTAyNCUyMTJpNzY4JTIxNGYxMy4xJTIxM20zJTIxMW0yJTIxMXMweDcxZjMxM2MzNzBkNGEzNzElMjUzQTB4MTQ2NTM5ODE2NDcxZjhiOSUyMTJzSHVuZ2ElMjUyMFRvbmdhJTIxNWUxJTIxM20yJTIxMXNkZSUyMTJzYXQlMjE0djE3NzQwODg2MDU5ODYlMjE1bTIlMjExc2RlJTIxMnNhdCUyMiUyMHdpZHRoJTNEJTIyNjAwJTIyJTIwaGVpZ2h0JTNEJTIyNDUwJTIyJTIwc3R5bGUlM0QlMjJib3JkZXIlM0EwJTNCJTIyJTIwYWxsb3dmdWxsc2NyZWVuJTNEJTIyJTIyJTIwbG9hZGluZyUzRCUyMmxhenklMjIlMjByZWZlcnJlcnBvbGljeSUzRCUyMm5vLXJlZmVycmVyLXdoZW4tZG93bmdyYWRlJTIyJTNFJTNDJTJGaWZyYW1lJTNF A broad view of…

The Cold Truth: Antibiotic Resistance in the Cryosphere

By Yannika Baier Cryosphere & Climate, Expedition, Feldbericht, Field report, Kryosphäre & Klima, Polar Ecology

Microbes from arctic environments. (© Daniel Gattinger) Antibiotic resistance was long considered a largely human-made problem, confined to urbanized areas and clinical settings. However, recent discoveries challenge the assumption that remote environments are inherently protected from this phenomenon. The cryosphere—the…

Freya Glacier: Avalanches do matter!

By Yannika Baier Cryosphere & Climate, Field report, Glaciology

While rising temperatures in the Arctic are increasing glacier mass loss by extending the melt season, they may also lead to an increase in snow accumulation as warmer air can carry more moisture. While the first effect dominates overall and…

Why Care for Plastics in Polar Regions?

By Iris Blog, Cryosphere & Climate, Polar Ecology

In these days, the term “microplastics” is already inflationary. There is literally no escape from media reporting: we are nearly daily confronted with the fact that our oceans suffer from massive loads of plastic litter which is mirrored by worrisome…

Why is the Arctic Relevant for our Weather and Climate?

By Iris Climate Change, Cryosphere & Climate, Klimawandel, PolarTalk

Climate change in the Arctic and its consequences for nature and people are widely reported in the media. What is much less well known is that climate change is particularly pronounced in the Arctic and has a direct impact on…

Climate Change in Greenland: Timing of lake ice break-up and its consequences

By Iris Blog, Climate Change, Cryosphere & Climate

APRI scientists from the CC-MoRe (Climate Change in Mountain Regions) research group at the University of Graz investigated the timing of the seasonal ice cover break-up of lakes in Greenland and identified its strong dependence on altitude. The temperatures of…

Antarctic Peninsula Glacier Response to Climate Change

By Iris Blog, Climate Change, Cryosphere & Climate

The climate-induced collapse of the Antarctic Peninsula ice shelves Larsen A in 1995 and Larsen B in 2002 caused acceleration and retreat of tributary glaciers, leading to major losses in ice mass. Since then, the glaciers have been out of…
