Thirst for Knowledge: How warm is too warm for Antarctica? 3-million-year-old lessons in a higher CO2 world

When we think of climate change and Earth’s temperature, what difference does half a degree make?

Clues to Antarctica’s response to warmer climates are preserved in the marine sedimentary record that has accumulated kilometers deep in the Southern Ocean. Evidence dating back to 3 million years ago tells us that Antarctic ice sheets and ocean circulation have responded sensitively to small changes in climate during this time.

So what does the geological history of Antarctica can tell us about Earth’s response to climate change today?

Come listen to Dr Christina Riesselman from the Departments of Geology and Marine Science at Otago Uni discuss her fascinating research on this topic.

No science background required. Just a healthy thirst for knowledge!
