From feeding polar bears to helping cool the planet, Arctic sea ice plays a vital role in the global climate and northern ...

Picture sea ice in your mind. You probably imagine brilliant white, snow-covered floes floating on the surface of the ocean, home to penguins in the south of the globe or polar bears in the north. But ...

The disappearance of sea ice in polar regions due to global warming not only increases the amount of light entering the ocean, but also changes its color. These changes have far-reaching consequences ...

Rapid sea ice loss and ocean acidification from climate change are altering the growth and nutritional value of microscopic algae. These algae are an essential food source for fish, krill, and other ...

If you were to slice a chunk of Arctic sea ice and peer at it under a microscope, you probably wouldn’t expect much. Frozen water, trapped sediment, perhaps a few still-living microbes locked in ...

Dark algae that grow on the surface of Arctic ice sheets are likely to expand their range in the future, a trend that will exacerbate melt, sea level rise and warming. “These algae are not a new ...

A research vessel in international Arctic waters near Russia unearthed a new development in the rapid melting of the ice caps that could have significant ramifications for the polar ecosystem. A team ...

This is one of the main indicators of the climate crisis. The melting ice caps, with their cumulative surface area around the two poles reaching a historic low in February, have many repercussions: ...

OSLO (Reuters) - Climate change is stirring life in the Arctic Ocean as thinning sea ice lets in more sunlight, allowing microscopic algae to bloom in the inhospitable region around the North Pole, ...
