Climate change expected to reduce the quality of ground-based astronomical observations 02 Oct 2022 Climate change will negatively impact the quality of ground-based astronomical observations and is likely to increase time lost due to deteriorating site conditions. That is the conclusion of an analysis of changing trends in observing conditions across eight worldwide sites. The authors say it is now vital that astronomers consider long-term climate projections when selecting sites to host future telescopes. The quality of astronomical observations by ground-based telescopes is significantly influenced by climate conditions. Sites for observatories are often placed at high altitude to take advantage of increased atmospheric clarity and such locations are carefully selected for favourable climate conditions such as low temperature and water vapour.
