I think we need to be more specific rather than more general (though there's no harm in brainstorming). "Scientific programming for environmental applications" contains a huge number of possibilities. I don't have difficulty coming up with things that I would like to do given time and energy, but committing to one thing instead of wondering about a dozen things is harder. Right now, I'm interested in the [[Zero carbon Britain 2030]]'s energy model, see the diagram of the network in [[Azimuth code challenges]]. But is anyone else enthusiastic? Will I be in a month's time? Even here, I suspect, the project is too vague so far.
