Forests provide habitat to more than 65% of terrestrial biodiversity, yet are being eliminated or greatly simplified at an alarming rate under global change (GC). Current forestry practices tend to favour a handful of species, without considering resilience of resulting forests to GC. During the past two decades, studies have investigated the complex relationships between biodiversity and ecosystem service provision to humanity.
The wild food system of northern Quebec is a critical natural resource, health resource, and cultural resource of the people of Eeyou Istchee and Nunavik, which has and will be impacted by climate change in many, diverse ways. The research proposed here seeks to identify the likely climate change impacts on key wild food species as well as the adaptation strategies that enable the maintenance of traditional food security in changing environments.
The rate of the current climate change strongly modifies the frequency, the duration and the intensity of extreme events, such as droughts, heat waves or extreme precipitation. Strong rates of greenhouse gases emissions can cause a destabilization of a component of the climate system (e.g. the sudden melt of the Arctic sea ice). Such a phenomenon is called an abrupt change. The aim of this internship is to create a catalogue of changes in the characteristics of climate events (mainly climate and weather extremes) due to an abrupt change.
Regional Climate Models (RCMs) allow generating climate-change projections into the future over a limited region of the globe at high spatial resolution. The production of large ensembles of simulations from a same RCM is an emerging field of research allowing to explore in detail the interaction between climate change, natural climate variability and extreme events, at the local scale where climate impacts occur.
Several studies have shown that water levels of the Great Lakes would inevitably decline in a warmer climate. These studies were based on a modeling system that was not accounting for two-way exchanges of water and energy between the atmosphere and the earth surface, hence excluding key feedback mechanisms. The general objective of this project is to improve our understanding of the Great Lakes water resources and its sensitivity to climate change.
Human influence on current climate change is now unequivocal. The rate of greenhouse gas (GHG) emissions continues to increase, and climate models and observations show that climate changes are accelerating in response to these emissions. In this context, the rate of the current climate change strongly modifies the frequency and the intensity of extreme events, such as droughts, heat waves or extreme precipitation. Strong rates of GHG emissions can cause a destabilization of a component of the climate system (e.g.
