Leaf Volatile Emissions Structure Tree Community Assembly and Mediate Climate Feedbacks in Tropical Forests
… critical components of the coupled biosphere-climate system. Climate change threatens tropical forests with rising temperatures and increasing variability of precipitation. Their response will influence future biodiversity as well as the fate of the climate. Understanding the physiological …

Links between climate feedbacks and the large-scale circulation across idealized and complex climate models
… frameworks: One that uses radiative forcings and feedbacks to investigate the thermodynamics of the response, and another that uses circulation feedbacks and thermodynamic constraints to investigate the dynamics of the response. In this thesis, I aim to help bridge the gap between these two …

Seasonal characteristics of phytoplankton bloom phenology in the northern Benguela Upwelling System
… a crucial role in ecosystem services and driving climate change through air-sea gas exchanges. Upwelling systems are particularly are sensitive to effects of climate change including the transport of nutrients, which influence the composition of phytoplankton communities. This is important because …

Investigating the ice nucleation activity of organic aerosol
… of aerosol particles and their precursors affect climate directly by scattering radiation and indirectly by altering cloud properties. Aerosol-induced ice nucleation includes several processes that impact cloud formation, lifetime, albedo, and precipitation efficiency. Ice nucleating particles …

The effects of elevated CO2 and ocean acidification on the production of marine biogenic trace gases
… and is a major influence on biogeochemical climate feedbacks. Halocarbons are also important biogenic trace gases which undergo atmospheric photochemical degradation, releasing halide radicals to participate in atmospheric ozone cycling, and transfer halogens from sea to land. Evidence is …

A Continental-Scale Investigation of Factors Controlling the Vulnerability of Soil Organic Matter in Mineral Horizons to Decomposition
… pool of organic carbon (C), and potential carbon-climate feedbacks involving SOM decomposition could exacerbate anthropogenic climate change. Despite the importance of SOM in the global C cycle, our understanding of the controls on SOM stabilization and decomposition is still developing, and as …

Development and Stakeholder-informed Evaluation of Global Climate Temperature Response Functions
Modern climate models allow for accurate simulation over a range of future climate scenarios. However, there exists a significant gap in terms of speed, accuracy, and overall intuitiveness between the stateof-the-art and more generally accessible tools, especially in tools used for climate …

Geochemistry of karst deposits in Borneo detailing hydroclimate variations in the Warm Pool across the late Pleistocene
… ocean-atmospheric system causes global scale climate anomalies, most evident in the El Niño-Southern Oscillation’s coupled climate feedbacks. Despite being an area of high interest, many questions still remain regarding the west Pacific warm pool’s response to external forcing, particularly …

Improved estimates and understanding of interannual trends of CO₂ fluxes in the Southern Ocean
… the effects of anthropogenically driven climate change. The region accounts for 43% of oceanic uptake of anthropogenic carbon dioxide (CO₂). This is foreseen to change with increasing greenhouse gas emissions due to ocean chemistry and climate feedbacks that regulate the carbon cycle in …

Mechanisms of Coral Calcification: a Geochemical and Computational Approach to Understanding Biomineralisation
… and play a critical part in the carbon cycle and climate feedbacks. In the face of a rapidly changing climate, the future of these reefs is uncertain. Corals also provide us with an invaluable archive of past ocean conditions through the impurities incorporated into their aragonite skeletons as …

Plume to global-scale atmospheric impacts of aviation emissions
… the atmospheric composition, alter the Earth’s climate by accounting for ~4% of anthropogenic radiative forcing [72, 49] and affect surface air quality, causing an estimated ~16,000 premature mortalities per year [7, 28]. These environmental impacts are driven by chemical, microphysical and …
