Description - summary of the module content
Module description
This module will cover the most important drivers of orbital to centennial-scale environmental change in tropical systems, with a particular emphasis in the American tropics and subtropics. The module content will combine advanced concepts of climatology, biogeography, and environmental archaeology. Lectures will cover the Younger Dryas, megafauna extinctions, quantitative methods for palaeoenvironmental reconstructions, probabilistic chronologies, and the 1491 hypothesis, among other topics of current scientific debate regarding long-term environmental change in the Neotropics. This module will allow you to put current and future threats to tropical biodiversity into a historical context, and to critically evaluate global-change environmental policies regarding some of the richest forests on earth.
Module aims - intentions of the module
The overall aims of this module are to develop an understanding of past global climate changes and their signature in tropical systems, learn new approaches of climate reconstruction and get familiar with quantitative analysis of palaeodata. We will explore and discuss glacial-interglacial cycles, millennial-scale climate variability and historical records from the Amazon and the tropical Andes. Practical sessions will introduce you to novel tropical palaeoenvironmental markers, multivariate statistics, palaeodata manipulation, and Bayesian probability analyses.
The coursework of this module will allow you to develop effective communication skills for broad non-specialist scientific audiences, while the practical exercises will introduce you to computational and programming skills desirable in today’s employment market.

Re-assessment notes
Deferral – if you miss an assessment for certificated reasons judged acceptable by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.
Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you will be required to sit a further examination or submit a further assessment as necessary. If you are successful on referral, your overall module mark will be capped at 40%.
