Diurnal temperature range: A climatological primer for health researchers
Published in PLoS One, 2026
A 1950–2022 ERA5-Land analysis finds that diurnal temperature range has significantly declined across most of the continental U.S., driven by minimum temperatures rising faster than maximums due to increasing humidity, cloud cover, and precipitation—suggesting reduced health risk from anthropogenic warming, though clinical evidence is still needed to confirm DTR’s direct causal role in health outcomes.
