An interesting looking conference at the Royal Society in October:
Warm climates of the past - a lesson for the future?
In several periods in Earth's history, climate has been significantly warmer than present. What lessons about the future can be learnt from past warm periods? The answer depends on the quality of reconstructions of past climates, our understanding of their causes, and the validity of climate models which aim to reproduce them. This meeting will address these exciting and challenging issues.
