My research focuses on the effects of anthropogenic emissions of greenhouse gases and aerosols on climate on multi-centennial timescales. The goal is to better understand the response of the climate system to forcing and the interactions between climate system components (the atmosphere, ocean, land surface, biosphere and cryosphere) in order to improve predictions for the future. To achieve this objective, I use climate models of different complexity, from simple conceptual models to complex Earth System models.

My main research interests lie in climate change and ocean acidification as well as in the related changes in the biosphere. In particular, I am interested in the question how the Earth system responds to different future scenarios of anthropogenic greenhouse gas emissions that eventually reach the same cumulative emissions but differ in the emissions trajectories, including overshoot scenarios with negative carbon dioxide emissions.

My doctoral research focuses on the modelling of wetland methane emissions, particularly from northern permafrost regions. The principal objective of this research is to investigate the permafrost carbon feedback and its implications on the global climate.

With climate change projected to increase global surface temperature further, particularly at northern high latitudes, it is important we understand how northern Earth systems will respond to these changing conditions. My research seeks to understand the effect of different emission pathways and levels of warming on the extent of permafrost in the circumpolar north.

Modelling the Earth system response to artificial atmospheric carbon dioxide removal on the coupled climate-carbon cycle system. The goal of my research is to understand the effects of atmospheric carbon dioxide removal on the progression of climate change.

My research focuses on carbon cycle feedbacks under negative (decreasing) emissions. Past research has focused on carbon cycle feedbacks under positive (increasing) emissions. However, carbon dioxide removal technologies are an essential part of emissions scenarios that constrain warming to 2°C above preindustrial levels. Therefore, an understanding of carbon cycle feedbacks under negative (decreasing) emissions is key to better predict future changes in the climate and carbon cycle.

I use a coupled climate model of intermediate complexity and a high-resolution ice sheet model to represent the interactions between the Greenland Ice Sheet and the climate. The aim of my research is twofold. First, we are seeking to quantify the level of cumulative CO2 emissions that will cause the ice sheet to completely melt. Then we examine whether this process is reversible and the related consequences for global sea-level rise.

Nadine is currently involved in testing and tuning the newest version of the University of Victoria Earth System Climate Model (UVic ESCM). This model is her main tool to conduct scientific experiments, such as assessing the carbon cycle uncertainty of carbon budgets. While at SFU, Nadine is going to investigate temperature overshoot scenarios and the impact of the associated negative emissions on the Earth system.
