In Episode 16, I meet environmental campaigner and journalist John Gibbons. John & I have sparred a few times on the radio over the years but I very much enjoyed the chance for a longer and more constructive chat.

I dropped out to him in his Dun Laoghaire home and we spoke about the scale of the climate challenge facing us, what Ireland can do and whether we are making progress. Along the way we learn a bit more about him, not least the fact that he knows his cars and enjoys driving.
