10. Lecture: Poles apart – climate change at the ends of the earth, 30 June, Wellington
“The last time carbon dioxide levels in the atmosphere were this high was 3 million years ago, and sea levels were 20 metres higher than today.” That’s according to Victoria University of Wellington Professor James Renwick, whose sobering comment comes ahead of his upcoming inaugural lecture—a public address to mark his professorial promotion.
Tempering this stark statistic just slightly, Professor Renwick notes that, unless methods can be found soon to significantly reduce carbon dioxide levels, future generations will likely face several metres of sea level rise—a prospect which will affect billions of people.
By primarily drawing comparisons between the two poles, Professor Renwick’s address, entitled A Tale of Two Hemispheres, will marry the science of man-made climate change with known natural occurrences in earth systems.
The focus will be on factors such as polar geography, the ozone hole, wave patterns and natural climate variations to show that, while the planet is warming overall, the impact will affect regions differently.
Details: 6pm Tuesday 30 June, Memorial Theatre, Student Union Building, Kelburn Campus, Victoria University of Wellington. RSVP by Friday 26 June. Phone 04-463 6300 or email firstname.lastname@example.org with ‘Renwick’ in the subject line. View website.
