The impact of climate change on astronomical observations

A Publisher Correction to this article was published on 20 May 2021

This article has been updated

Climate change is affecting and will increasingly affect astronomical observations, particularly in terms of dome seeing, surface layer turbulence, atmospheric water vapour content and the wind-driven halo effect in exoplanet direct imaging.
