What to know about climate_change

Researchers from the Alfred Wegener Institute have published a study in Nature Communications regarding 'cyclone clustering' in the Arctic. The research indicates that successive low-pressure systems cause more significant sea ice loss than isolated storms, increasing the vulnerability of Arctic coastlines.

What happened

Arctic cyclone clusters batter sea ice, leaving coasts more exposed to storms Swati Mestri Scientific Editor Robert Egan Senior Editor In the Arctic, weather plays a key role in determining how much ice covers the ocean.

Why it matters

Arctic cyclones are one weather phenomenon with a significant influence, causing unusually warm and stormy conditions that typically lead to significant ice loss.

Common ground

These conditions last particularly long when several cyclones rapidly follow one another.
