I was a teenager in 1988 when James Hansen gave his congressional testimony on climate change.
It was the first time I’d seen the dangers of greenhouse gases laid out so clearly — and alarmingly. Being a science nerd back even then, I dove into the nascent literature about CO2 and other heat-trapping gases, and it scared the living crap out of me.
So when I became a freelance magazine journalist in the mid 90s, I decided I wanted to write about climate change and energy as much as possible.
