Summer sea ice in the Arctic Ocean might be gone by the 2030s, no matter what we do to curb emissions of greenhouse gases, study says.

A Facebook post links to an article with a graph that purportedly shows Arctic sea ice extent data for mid-April through mid-May in 2007, 2018, 2021 and 2023. The graph indicates the Arctic sea ...

Meteorologist Sven Sundgaard explains how Arctic sea ice has a direct impact on Minnesota's climate.

Harmful algae blooms have been rapidly producing in a place previously too cold to host the toxin: the Arctic.

Arctic sea ice had its weakest winter buildup since record-keeping began 47 years ago, a symptom of climate change that will have repercussions globally, scientists said Thursday.

Researchers are warning that Arctic Ocean sea ice is melting at an even faster pace than previously thought — and the region could experience its first ice-free conditions sometime before the 2030s.

Arctic temperatures spiked 36 degrees Fahrenheit, or 20 Celsius, above normal. By the end of the month, sea ice was at its lowest level ever recorded for February.

As Arctic sea ice begins melting out fully in summer, the frequency of strong El Niños could increase by 35% by century's end, causing extreme weather events to increase, says recent modeling study.

The Arctic could be free of sea ice roughly a decade earlier than projected, scientists warn – another clear sign the climate crisis is happening faster than expected as the world continues to ...
