You cannot accuse of us of not catering for minority interests! Here, I have to admit that I took a degree in Geology many moons ago (although a pinhead in Geologucal time) so I might be biased.

The Pyrenees form a mountain range in western Europe that links the Atlantic Ocean and the Mediterranean Sea. Because they are highly sensitive to variability in the North Atlantic atmosphere-ocean circulation system, the Pyrenees are ideally located for retrieving valuable climatic information of the past. However, the age of Pyrenean glacier fluctuations is not well established. A combination of dating methods suggests a long period of maximum and near-maximum ice extent ranging from more than 30,000 to 20,000 years ago. However, this interpretation is challenged by ecological reconstructions based on pollen-bearing lake sediments that indicate increased aridity in the Mediterranean region during the global Last Glacial Maximum (the period between 23,000 and 19,000 years ago). Raimon Pallas of the University of Barcelona and colleagues showcase the potential of small, isolated, low-gradient glacial catchments to improve the chronology of peak glacial fluctuations using specific isotopes that accumulate at Earths surface under the effect of cosmic radiation. Focusing on a small catchment in the southeastern Pyrenees, they present a new data set that introduces unprecedented coherence to the Pyrenean chronology while also narrowing discrepancies between glacial and ecological reconstructions in the Mediterranean region.
