Can the member tell us what the influences were down through the ages for climate change, and in those periods of climate change were there people, other than in literally volcanic situations, who were having their lungs seared, and were there other such cataclysmic changes where suddenly people were dropping dead?
Le député peut-il nous dire qu'est-ce qui, au fil des temps, a influencé les changements climatiques et si, pendant les périodes de changement, il y eu des gens qui ont eu les poumons brûlés dans des conditions autres que des éruptions volcaniques? Y a-t-il eu d'autres cataclysmes qui ont fait périr des gens subitement?
