Polar bears are expected to become extinct but there are some signs their DNA is changing and they are adapting to new ...

In an age of rising sea levels, as polar ice sheets melt in a climate warmed by fossil fuel emissions, climate modelers are racing to understand what the future might hold for coastlines around the ...

In yet another sign that winter weather is either here or will be soon, the dreaded polar vortex is making news yet again. Its potential arrival in the United States over the next few weeks is cause ...

MIT astronomers used the Imaging X-ray Polarimetry Explorer to identify key features in the innermost region of a white dwarf system called an intermediate polar. This extremely energetic environment ...

An extreme warming event high in the atmosphere is threatening to disrupt the polar vortex. We break down what that could mean for Canadians A rare, early, stratospheric warming event could shake up ...

High above the North Pole, in a slice of atmosphere rarely noticed and even less understood, a transformation is underway. Over the next 10 days, changes in the stratosphere will upend weather ...

Climate change in Earth's polar regions is emerging as an underrecognized driver of global health risks, with consequences reaching far beyond the Arctic and Antarctic, researchers argue. A study by ...

At a shipyard in Finland last month, workers cut the first steel for a new icebreaker ship. Over the next three years, about 10,000 tons of the metal will go into the hull before the vessel is carried ...

Proposals to artificially cool the world’s polar regions — to stem the impact of global warming — are both expensive, unfeasible and potentially dangerous, according to new scientific research. The ...

A team of international scientists is urging caution against five of the most-discussed polar geoengineering ideas, stating they are highly unlikely to help the polar regions and could harm ecosystems ...
