Damon Matthews of Concordia's Geography, Planning and Environment Department, who contributed to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), is unequivocal about the impact of human activities on global temperature.
"Climate change is real, it is happening, and it's mostly our fault," he said. "It is high time that we stop debating the question of whether global warming is a problem, and move on to the much more important question of what to do about it."
Using computerized climate models, Matthews is currently studying the resilience of the Earth's carbon sinks to find out precisely how much carbon dioxide we can emit if we want to stabilize levels of carbon dioxide in the atmosphere.Computer modelling allows climate scientists to make fairly accurate predictions about the long-term effects of greenhouse gas emissions.
