Jonathan Adams has a very diverse background in the environmental sciences, including biogeography, classical ecology, Quaternary geology and earth system science. He has published in international journals on all of these topics and collaborated with some of the best known scientists in these fields. He has also organized meetings and edited special issues of journals on earth system science. Thus, he has the inter-disciplinary knowledge necessary to tackle a subject as far-reaching and many-faceted as vegetation-climate interactions, on a range of spatial scales and time scales.
