There's new evidence from an Antarctic ice core that the popular image of the melting poles doesn't quite fit reality at the southern one. Elizabeth R. Thomas of the British Antarctic Survey and colleagues report in Geophysical Research Letters that snow accumulation has doubled since 1850 in the western Antarctic peninsula, and that the trend [...].
