A new study has found a significant statistical correlation between thunderstorms occurring around the world and the formation of wispy cirrus clouds—which might increase global warming. The researchers say, "We know that cirrus clouds can contribute to global warming. However, it is very difficult to track these clouds and obtain accurate data about them. Our findings indicate that a rise in the number of thunderstorms occurring globally might significantly increase the quantity of cirrus clouds, thereby exacerbating the climate crisis."
