Extra carbon in the atmosphere may disrupt radio communications

SMRTR summary

Rising carbon dioxide levels cool the ionosphere, reducing air density and accelerating wind circulation, which enhances disruptive plasma irregularities that interfere with radio communications. Japanese researchers found that doubling CO2 concentrations from 1958 to projected 2100 levels significantly increases these disruptions, potentially causing more noise and frequent interruptions for aviation, shipping, and emergency radio systems.
