Hi @christophberger ,
Science tells us climate change is not “the biggest challenge for the global society” but merely one of the many problems we have to deal with long term.
Other than that, here is how we use Go for climate purposes: every code review of an algorithm asks “can it be done with less electricity” (instead of the “can it be done with a better CPU complexity”).
Somehow thinking about electricity consumption makes developer to be more motivated about their algorithms. I have seen this at work multiple times.
