Relative humidity over land decreases in a warmer climate as a result of interactive soil moisture response.
Remote sensing measurements for water vapor isotopic composition enable us to assess how convective aggregation influences the atmospheric hydrological cycle.
Smaller cities in these regions are less likely to have infrastructure to deal with extreme climates.
Whether warming increases or decreases, rain over land depends on the relationship of soil moisture, evaporation, and aridity which shape rain regimes.
High humidity and low temperature altered COVID-19 spread in Brazil, but only slightly.
Data scarcity of traditional observations cannot reveal whether surface temperature capture the potential for urban heat stress. This study improves the dataset with 40,000 citizen weather stations.
When temperatures exceed 36°C and relative humidity passes 58%, citizens in China may experience heat stroke.
Humidity increases with warming. Theory and observations about how increased humidity translates into more extreme rainfall can be reconciled if attention is paid to data and methods.
The choice of a fixed relative humidity leads to a simpler picture of climate feedbacks than fixing absolute humidity.
