      How Stable Is the Antarctic Ice Sheet?

      As temperatures rise due to climate change, the melting of polar ice sheets is accelerating. An international team of scientists has now examined the dynamics of the East Antarctic Ice Sheet more ...

      Ice Sheets on the Move: How North and South Poles Connect

      Over the past 40,000 years, ice sheets thousands of kilometers apart have influenced one another through sea level changes, according to new research. New modelling of ice sheet changes during the ...

      Darwin's Theory About Coral Reef Atolls Is Fatally Flawed

      Charles Darwin's 1842 theory about the formation of ring-shaped reefs, called atolls, is incorrect, but 'it's so beautiful, so simple and pleasing' that it still appears in ...

      Meltwater Lakes Are Accelerating Glacier Ice Loss

      Meltwater lakes that form at glacier margins cause ice to recede much further and faster compared to glaciers that terminate on land, according to a new study. But the effects of these glacial lakes ...

      Ice Melt Projections May Underestimate Antarctic Contribution to Sea Level Rise

      Fluctuations in the weather can have a significant impact on melting Antarctic ice, and models that do not include this factor can underestimate the global impact of sea level rise, according to ...

      Extinctions Linked to New Assemblages of Species

      As the world undergoes profound environmental change, identifying and protecting 'novel' communities of species can help prevent extinctions within vulnerable ecosystems. Scientists outline ...
