The costs of climate change are often estimated in monetary terms, but this raises ethical issues. Here we express them in terms of numbers of people left outside the ‘human climate niche’—defined as the historically highly conserved distribution of relative human population density with respect…
We show that for thousands of years, humans have concentrated in a surprisingly narrow subset of Earth’s available climates, characterized by mean annual temperatures around ∼13 °C. This distribution likely reflects a human temperature niche related to fundamental constraints. We demonstrate that depending on scenarios…
Throughout history, humans have predominantly inhabited a surprisingly limited range of Earth's diverse climates, typically characterised by a mean annual temperature of around 13°C, i.e. human climate niches. [Lire plus...]
