Quantifying the health impacts of future changes in temperature in California

► We quantified the health effects from estimated temperatures in California for 2025 and 2050. ► Dose-response functions were combined with projections from several emissions models. ► Annual premature mortality ranges from 2100 to 4300 for 2025 and from 6700 to 11,300 for 2050. ► Estimates using age-specific concentration-response functions generate the highest effects. ► Estimates using the low emissions scenario are roughly half of these estimates.
