The ozone hole, climate change and the Canadian Arctic

This edition of the podcast explores the story of the ozone hole
during the 1970s and 80s and what lessons can be learned from
this environmental problem for dealing with global warming. It
suggests that not applying the cautionary principle to the ozone
thinning in the 1970s led to the emergence of the so called hole
in the ozone layer. In the second half of the podcast Liza Piper
explores the question how the arctic environment shaped Northern
Canadian society during the last stages of the Little Ice age and
why this is relevant for the present.
