Huge lakes under glacier challenge ideas on sea level rise

Australian scientists have discovered huge lakes under the Totten glacier in East Antarctica. This new revelation is causing a rethink in how ice melt from Antarctica will raise sea levels. More research is needed to get a clear picture of how…

Not quite so bad? New research on ice loss

The direst predictions of sea-level rise caused by melting Antarctic ice sheets may not come about, so says new research published in Nature. However, the impact of ice loss on the climate are still not fully understood and may even be worse…
