Aphids are emerging as sentinels of climate change, researchers at BBSRC-supported Rothamsted Research have shown. One of the UK's most damaging aphids – the peach-potato aphid (Myzus persicae) – has been found to be flying two weeks earlier for every 1°C rise in mean temperature for January and February combined.

Permanent ice fields are resisting global warming

The small ice caps of Mont Blanc and the DÃƒÂ´me du GoÃƒÂ»ter are not melting, or at least, not yet. This is what CNRS researchers1 have announced in the Journal of Geophysical Research. At very high altitudes (above 4200 meters), the accumulation of snow and ice has varied very little since the beginning of the 20th century. But if summer temperatures increase by a few degrees during the 21st century, the melt could become more marked, and could affect the "permanent" ice fields.
