Kirsten Zickfeld is a co-lead on Activity 13, her research focuses on the effects of anthropogenic emissions of greenhouse gases and aerosols on climate on decadal to century timescales, with particular emphasis on four broad themes: reversibility of human-induced climate change, Earth system response to carbon dioxide removal, carbon budgets consistent with climate targets, and feedbacks between climate and the carbon cycle. She is a lead author for the recently released Working Group I (WG1) Contribution to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) and the IPCC Special Report on the Global Warming of 1.5 degrees. She is the SFU Distinguished Professor of Climate Science in the Department of Geography.
