Historically, the idea of the sublime is often associated with grand and astounding natural scenery. This thesis investigates a twenty-first century idea of the sublime that includes dissonant phenomena such as ecosystem disruption and climate change. The subject of the sublime is symbolic of how unprepared the general audience is for dealing with the inherent disorders that arise when confronted with ‘negative’ aesthetic engagement. Landscape design, however, can mediate this experience to facilitate a creative act of imagination and identification with contemporary sublime phenomena. This in turn provides an opportunity to speculate on a future landscape architectural repertoire.
