G5a - the distinctive coarse-grained, pink granite exposed at Shap in Cumbria - has long been a favourite igneous hand specimen for Earth Sciences teaching in Cambridge. New research uses the age of zircon crystal formation to suggest a long gestation period in the mid-crust before its final emplacement 405 million years ago.

Selected intervals in the past that were as warm or warmer than today can help us understand what the Earth may be like under future global warming. A latest assessment of past warm periods, by an international team of 59 scientists from 17 nations including Cambridge Earth Sciences' Professor Eric Wolff, shows that in response to the warming ecosystems and climate zones will spatially shift and on millennial time scales ice sheets will substantially shrink.
