DRAFT, IN PROGRESS
Language and similar terms are used in the broadest possible sense here initially, to capture climate-relevant scales and timescales. These terms can be narrowed for specific contexts, matching how they are used in various bodies of literature.
This explains why Max Tegmark and the late Ludwig Wittgenstein are good starting points for analyses of language and mental models.
This allows visualizing for example the carbon-intensity of activity via
—Tegmark’s (2017) broad definitions of Life 1.0, 2.0, 3.0; and
—Wittgenstein’s philosophy of language learning (e.g. Lebensform / lifeform, grammar, language games).
Waterfall model is used here as an early metaphor for mental models and the dynamics of learning and human knowledge. It will change as research progresses.
