It's not entirely clear, that we can use e.g. deserts "for free". Changing the albedo of significant amounts of surface can have far reaching consequences. And unlike already populated areas (were this already happened), we don't really know what will happen there (probably until we try)
- spookie 2y agoThis is a good point. Urban areas are responsible in part for "global warming", just by their albedo. [1] [1] https://doi.org/10.1038/s41467-022-31558-z https://doi.org/10.1038/s41467-022-31558-z
