I saw Greta Thunberg for the first time in Poland at the end of last year. It was during the early days of the Katowice UNclimate negotiations. She was sitting in a makeshift TV studio, having her pigtails re-tied. I was in a hurry, chasing too many stories down at once, and paid little attention to this 15-year-old girl.Of course, I’d heard of Greta by that point. I’d received several emails inviting me to press conferences where she was speaking, but I hadn’t taken the bait.
