John Brinnard lives in a wonderful place just west of Yandina on Queensland's Sunshine Coast, in a lush piece of forest you could never imagine burning, but after a long, dry spell, that's exactly what happened - bushfire!

Was that attributable to climate change? John, in his quiet and considered manner, didn't jump to that conclusion, but he had never seen the bush near his home so dry before or after.

John is big on people giving themselves agency through involvement with others concerned about climate issues, and so he has supported "Rising Tide" playing an active role in the group's protests at the Port of Newcastle.

He is also involved with the "Urgent Climate Action Network Sunshine Coast ".

Professor Ian Lowe lives in the small coastal town of Marcoola on Queensland's Sunshine Coast, a place he and his late partner moved to in retirement.

However, as he points out, once a scientist, always a scientist, and so he continues to devour scientific journals, engage in webinars and travel to conferences covering topics that embrace his interests.

The Professor has written many books and has been involved in ensuring others get published.

Ian has been a regular at the Woodford Folk Festival and recently was a guest on the day four edition of the podcast, "First Wine of the Day".

Although he spent some of his career in England, most of Ian's time was spent at Queensland's Griffith University.
