Dr. Nick Scroxton is a paleoclimatologist working on rainfall variability in past, present, and future climates. He specialises in using stalagmite geochemistry to reconstruct past rainfall variability in southern hemisphere tropical monsoon systems but has broad research interests relating to past climate variability in Ireland, working collaboratively with the Aid and Development sectors to climate proof real world adaptation and mitigation strategies, and working collaboratively with paleoanthropologists on human evolution, megafaunal extinctions and societal transformations.

Dr. Scroxton joined the Department of Geography and the Irish Climate Analysis and Research UnitS (ICARUS) at Maynooth University as an Assistant Professor of Climate Change in 2021. Prior to that he has worked at University College Dublin as an Irish Research Council/Marie Skłodowska Curie Cofund CAROLINE Fellow (2019-2021), a Postdoctoral Research Scholar and the University of Massachusetts and Massachusetts Institute of Technology (2015-2019), conducted a Ph.D. in Paleoclimatology at The Australian National University (2015), and gained an MESci in Earth Sciences (2009) and a BA in Geology at Oxford University (2008).

Research Interests

  • Reconstructing past rainfall variability and dynamics using stalagmite geochemistry, with a focus on southern hemisphere tropical monsoon systems, and a multi-proxy approach.
  • Past rainfall variability across Ireland, focusing on spatial heterogeneity and high resolution records.
  • Investigating the impact of past changes in climate, volcanism and human land use on past environments, including hominin, primate evolution and extinction, and civilization collapse.
  • Modern climate variability in southern Africa. Investigating emergent trends and future projections in rainfall variability using remote sensing and model outputs, and their impact on smallholder farmers and development strategies of agricultural development NGOs.

Teaching Interests

My main teaching interests revolve around teaching Climate Science in a positive, solution orientated manner, skills-focused courses that blend direct and transferable skills with content in practical-forward classes, and deeper dives into paleoenvironments and paleoclimates focusing on how as much as what, all with relevance to modern crises and their solutions.
