And it wasn't consistantly this high for millions of years. Normal for the end of an InterGlacial period would be low 300s. Last time the proportion of CO2 was above 400 for an extended period the average global temperature was nearly 20 degrees warmer. Our bodies can't handle a much higher heat and humidity combo than we already are hitting in the summer.

High wet-bulb temperatures, where sweat cannot evaporate effectively, pose a serious health risk, especially in extreme heat and humidity, as they can lead to heatstroke and death. The body's natural cooling mechanism fails, and internal temperatures rise dangerously.
