'I thought climate change was a hoax. Now I've changed my mind'
'I thought climate change was a hoax. Now I've changed my mind'

Sarah Ott spent years as a climate change sceptic - now she's an advocate for clean energy.

I spent years doubting the science of climate change and spending time with people who didn't believe in the science either.
When I realised I was wrong, I felt really embarrassed.
To move away from those people meant leaving behind an entire community at a time when I didn't have many friends.
I went through a really difficult time. But the truth matters.
I'm the granddaughter of coal miners in Pennsylvania and my family moved to Florida when I was young.
We have a Polish Catholic background and we attended church regularly, but at the same time we were very connected to science because my mum was a nurse and my dad sold microscopes and other scientific equipment.
