The Changing Arctic And Its Global Consequences

Professor Dr. Dr. H.C. Terry V Callaghan CMG
Tuesday, 3 November 2020 - 6:30pm

 

The Arctic is changing rapidly because of climate change and globalisation.  Increasingly, the two aspects are linked and changes in the Arctic's environment are accelerating.  Climate warming in the Arctic is much faster than the global average with new extremes of heat and harmful weather events.  Their consequences are having profound impacts on the frozen parts of the Arctic, its wildlife and its peoples.  The Arctic has for millennia acted as a corrective negative feedback loop to global warming by capturing and storing carbon and reflecting heat from the surface.  Melted ice means more heat absorption - a positive feedback loop with consequences for the whole Earth.  At the same time, declining sea and river ice is leading to new transport routes and improved access to resources that further impact the environment.  This illustrated talk gives examples of changes in the Arctic, their local consequences and the implications for the rest of the world.
