Feeling the heat? Got questions to ask about climate change? You’re not alone. Dr Karl Kruszelnicki and Tim Flannery have investigated this vexing subject as thoroughly as anyone. They join Nick Rowley for an enlightening discussion that answers many of your questions and poses a few more. From melting ice caps to the effect of rising sea levels on our coastlines, our response to these problems will matter – and sooner than we thought, it seems.
