On the edition of Your Call’s One Planet Series, we're discussing the impacts of climate change in Antarctica. Last week, the eastern part of Antarctica recorded temperatures around 70 degrees Fahrenheit higher than typical.

What's behind the recent heatwave, how fast is Antarctica warming, and what are the ramifications?
