Is it true that converting all landmass to desert would significantly alter Earth's global average temperature?

Yes. Extensive changes in land surface properties, such as converting vegetation to desert, modify surface albedo and radiation balance, which significantly impacts regional and global temperatures.

The analysis

The claim posits that converting all landmass to desert would significantly alter Earth's global average temperature. Retrieved papers such as [0], [5], and [7] provide evidence that land cover changes, vegetation alterations, and shifts in surface properties like albedo and dust mineralogy substantially impact surface energy balance, radiative forcing, and land surface temperatures. There is no evidence refuting the premise that large-scale land cover changes affect global temperatures.

Correlation between Increases of the Annual Global Solar Radiation and the Ground Albedo Solar Radiation due to Desertification—A Possible Factor Contributing to Climatic Change

2016

The simulation shows that converting forested or grassy areas to desert sand alters surface albedo and solar radiation absorption, which connects land cover modifications to climate change.
