Day 4

Day 4 contained the beginnings of the students towards developing (and presenting) their own research and ideas. The different 'controversies' now have groups of students thinking about them and developing ideas. These will be finessed over time into short, exciting research proposals. The participants of the school also had an opportunity to present research findings in parallel sessions at the

Day 3

Well, day 3, where do we start? Alan Robock and I were up to bat to talk about outdoor experiments - I am not sure our remit was better fleshed out than that. Controversy was desirable but never really likely given our relative positions - there are things we don't agree on for sure but at our core, for different reasons maybe, are similar values.

Both were illuminating, neither were particularly adversarial. Alexander did have to argue somewhat out of his comfort zone (a principle I am now familiar with) and I think did

Day 1

It's nice to see some old friends and some fresh new minds (I hope that geoengineering doesn't feel completely normal to the newbies and that I do not in any way normalise it).

A new framing

I am at a very interesting meeting (EuTRACE partner meeting - and we are discussing framing. I novel (I think) idea hit me. There are several framings, none of which are ideal. As a general discussion 'CE' is challenging because there are many different techniques that work on varying spatio-temporal scales, with variable costs, impacts and social responses. Is afforestation
