Enhanced response of extreme compound events to cumulative CO 2 emissions (opens in new tab)

Compound events—such as concurrent hot–wet and drought–heat extremes—are among the most consequential climate hazards on Earth1–4 and are projected to become more severe under warming. Although the transient mean temperature response to cumulative CO2 emissions has been well quantified5–8, the corresponding response of compound events remains less clear. Here we show that the response of the transient compound events to cumulative CO2 emissions (TCoRE), defined as the change in event frequenc...
