I gave my first ever public climate science talk at a Flight Free event in Edinburgh. If you’re interested in seeing my talk slides, you can download them here. The idea behind Flight Free is to encourage people to pledge to not fly in 2020.
In my talk, I mainly presented some of the basics (greenhouse effect, indicators of warming, consequences, and some of the possible impacts) and then some things that I’ve felt are quite useful to understand, but aren’t always appreciated (there is essentially no warming commitment, stopping climate change requires getting net emissions to zero, it’s going to be challenging, delaying emission reductions is likely to make it increasingly difficult). I tried to be partly hopeful (what we do now can make a difference) and partly somewhat more direct (the changes are probably irreversible and achieving some of our stated targets is going to be extremely challenging).
The other speakers were a Green party candidate, someone who runs a charity that tries to connect the arts and sustainability, and Anna Hughes, the UK Director of Flight Free. It was all quite measured and pleasant, and the audience were – as far as I could tell – quite engaged with the topic, and noone was adamantly demanding that everyone should stop flying (it was more about recognising some of the issues associated with flying and about considering limiting how much we fly). I enjoyed giving my talk and I thought it went okay; people were nicely complementary, but maybe they were just being polite 
I also got to meet some people I’ve only ever interacted with on Twitter, which was very nice, and I’m also going to meet someone from extinction rebellion next week, which should also be interesting. So, I enjoyed my first venture out of social media. Apart from meeting with someone from extinction rebellion, I have no immediate plans to do more, but I quite enjoyed stepping outside my comfort zone, so I may well try and do more, if the opportunities arise.
