Robust method predicts beginning of new climate in Arctic based on warming, wetting and sea ice loss

Scientists sound alarm after uncovering disturbing shift in Arctic survival patterns: 'The future ... will depend heavily on how well they adapt'

As our planet continues to warm, scientists are raising concerns about an unexpected consequence unfolding in the Arctic, EurekAlert reported — and it's being called the "cryosphere meltdown."  What's happening? A new study led by Jochen Knies and published in the Communications Earth & Environment Journal has found that Arctic fjords — particularly in places like Kongsfjorden, Svalbard — are undergoing rapid transformation. These icy, nutrient-…

“Cryosphere Meltdown” – The Arctic’s Carbon Sink Is Cracking

Though phytoplankton may grow more in warmer waters, stratification limits nutrients, reducing the fjords’ long-term carbon sink effectiveness. A new study led by Jochen Knies at the iC3 Polar Research Hub reveals troubling evidence that climate change may be weakening the ability of Arctic fjords to act as effective carbon sinks. As global temperatures rise, [...]

Robust method predicts beginning of new climate in Arctic based on warming, wetting and sea ice loss

When does "anomalous weather" become "a new climate"? The moment that variations in a specific climate variable turn into the new normal is termed Time of Emergence (ToE). Scientists from the University of Groningen and the Royal Netherlands Meteorological Institute (KNMI) have developed a method to predict the time of emergence in various Arctic regions, based on warming, wetting, and sea ice melting.

Temperatures that explode, ice that melts. The Arctic is one of the regions of the world most affected by warming. Can we conclude that its climate has changed? No. But it's coming soon.

MADRID 6 May. (EUROPA PRESS). – A new climate normal for temperature and sea ice in the Arctic is expected in the near future, by 2050, while rain will reach a similar state at the end of the century. Scientists from the University of Groningen and the Royal Meteorological Institute of the Netherlands (KNMI) have developed a method to predict this new climate normality – which they call ToE (Emergency Time) and exceeds the threshold of abnormal …
