Dear Science: New Zealand’s first city to go underwater

Sam Fraser-Baxter is back again this week for Dear Science. This week we chat to him about South Dunedin, and how it became New Zealand’s first city to go underwater back in June 2015 when it experienced massive flooding. We also talk to him about how the frequency and severity of  extreme weather events like this can be linked to global warming, and about why we as a nation kinda suck at tackling this problem head-on.
