I am an Emeritus Professor of Earth Sciences in the Department of Environment, Earth and Ecosystems and a Senior Visiting Scholar at the Chinese Academy of Sciences, Xishuangbanna Tropical Botanical Garden, Yunnan, China (http://english.xtbg.cas.cn/). Trained initially as a botanist at Imperial College London I subsequently obtained a PhD in Geology, also at Imperial College. That was followed by a three year period working with the United States Geological Survey at Menlo Park California first as a Lindemann Fellow and then as a Research Fellow of the California Academy of Sciences. On my return to the UK my first lecturing position was in the Life Sciences department of Goldsmiths College, London, followed by a move to Oxford University where I was a lecturer in Earth Sciences and a Fellow of St Hugh's College. I moved to the Open University as Professor and Head of Earth Sciences in 1994 and subsequently became the founding director of CEPSAR.
I have ongoing interests in using fossil plants as indicators of past climates with particular emphasis on the polar environments at times of global warmth, the uplift of the Tibetan Plateau and the development of the Asian Monsoon. I have an active research program in collaboration with staff at the Institute of Botany, Chinese Academy of Sciences, Beijing, for the development of the quantitative plant-based palaeoclimate proxy known as CLAMP (Climate Leaf Analysis Multivariate Program) http://clamp.ibcas.ac.cn.
I use plant fossil proxy climate data in relation to global climate modelling for past and present climates inclusing the essessment of uncertainties in both modelling and proxies.
Fundamental to understanding uncertainty in the proxies is determining the processes by which the plant fossil accumulations form (plant taphonomy) and how the these processes may affect the climate signal.
Plants are excellent climate indicators as we can readily see from the world around us. Plants in deserts have few, if any, leaves and those that they do have tend to be small. Rainforest trees and plants on the other hand can have very large leaves and often large numbers of them. These architectural features of plants are similar in similar climates so that rainforests, for example, in Africa, South East Asia and South America look alike even though they contain quite different species. This convergence of form is expressed in the architecture of the whole plant, but also strongly in the form of the leaves.
Leaves are readily fossilised so the geological record contains a vast amount of information about past climates. Qualitative surveys of rocks and fossils show that the average temperature of the Earth has fluctuated through time, but that for about 80% of the time that animals and plants have lived on land the world has been warmer than it is now. Using plant fossils we can quantify a range of parameters such as temperature and rainfall for those past climates. Climate Leaf Analysis Multivariate Program - CLAMP - is a powerful tool for decoding the signal of ancient climate encoded in leaf form. To learn more about CLAMP follow the this link http://clamp.ibcas.ac.cn.
The development of CLAMP is the focus of one of my current research projects being carried out at the Key Laboratory of Tropical Forest Ecology, Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Yunnan, P.R. China and the Birbal Sahni Institute of Palaeobotany, Lucknow, India. Another project uses CLAMP to track the uplift of the Himalaya and Tibet, as well as climate changes and biodiversity development associated with the evolution of the Asian monsoon systems.
