Personal news: I'm leaving BBC staff in June after 35 years reporting on environment and energy. It's been great - but opportunities beckon in the post-COP26 world. More later.
His former colleague Richard Black has paid tribute:
Privileged to have worked alongside this usually brilliant, occasionally infuriating but unfailingly interesting brain for a decade at BBC News … a big loss, very hard shoes to fill. Intrigued to see what comes next for you, Rog.
Thanks to everyone for the amazing tributes. I didn't know I'd need a hanky. I will be available for after dinner speeches, Bar Mitzvahs, weddings and funerals. Especially after dinners...
Meanwhile, I'm sure his remaining colleagues will keep up the good work.
Here are a couple of links that suggests some of them - including the famous Marianna Spring - are already off to a cracking start, trying to bind together groups of people the BBC disapproves of into one handy, easy-to-smear bundle:
Marianna's made a career over the past couple of years reporting on anti-lockdown protests and focusing only on the conspiracy theorists in attendance, so much so that she risks being seen as a one-trick pony. Therefore, it's nice to see that she's spreading her wings and beginning to apply this narrowly-focused approach to another group of people the BBC disapproves of - those who don't adhere to the BBC's line on climate change. I'm sure Roger will be proud of her.
