The Australian continent is characterised by an extremely variable surficial geochemistry, reflecting the varied lithology of Australian basement rocks. Samples representative of Australian aeolian dust have been collected in (1) regions... more

This paper is a response to claims made by John Fitzgerald regarding the age of the earth and the reliability of radiometric dating.
Lead pollution in Arctic ice reflects mid-latitude emissions from ancient lead-silver mining and smelting. The few reported measurements have been extrapolated to infer the performance of ancient economies, including comparisons of... more
... The 1.0 and 0.8%o reduc-tion in summer and winter Ô180 values, respectively, between AD 975 and AD 1720 signals the climate change from the highs of Medieval warming (Medieval Warm Period or MWP) to the lows of Little Ice Age (LIA)... more
Medieval Climate Anomaly (MCA) terrestrial proxy records (speleothem, NW Scotland; tree rings, Morocco) from close to the centres of action of the winter North Atlantic Oscillation (NAO) indicate that the MCA was characterized by a... more
The cosmogenic nuclide beryllium-10 (10Be), recovered from ice cores, is often used to study solar activity on long time- scales. However, the 10Be signal is also influenced by factors other than the Sun. To identify and quantify various... more
In order to track catastrophes, I depend upon layer counting of GISP2 ice core for accurate dates. While researching Clovis impacts, I discovered an error of fifty years due to a single snowfall a hundred times normal. This led to a quest... more
This study presents the results of a broad intercomparison of a total of 15 global aerosol models within the AeroCom project. Each model is compared to observations related to desert dust aerosols, their direct radiative effect, and their... more
