Environmental factors could influence the virus epidemic in humans; However, the association remains complex and the evidence is still unclear in human coronaviruses (HCoV). Our aim was to explore and compare the associations between the HCoV epidemic and environmental factors on a global scale. Data for four common HCoVs were collected through a systematic literature review, and data for MERS, SARS, and COVID-19 were collected from World Health Organization reports. Common positive monthly HCoV rates and incidence rates for MERS, SARS, and COVID-19 were calculated. Geographic coordinates were used to link virus data and environmental data. Generalized additive models (GAM) were used to quantitatively estimate the association of environmental factors with the HCoV epidemic. We found that there are broad associations between HCoV and environmental factors globally, and some of the associations were non-linear. Additionally, COVID-19 has the most similarities in the direction of associations with common HCoVs, particularly for HCoV-HKU1 in four environmental factors, including significantly negative associations with mean temperature, precipitation, land cover ( p
