The terrifying beauty of cloud seeding air pollution.
It is well-known that tiny ice crystals in the atmosphere create halos by refracting and reflecting light.
But are these crystals natural or man-made? To produce ice crystals, you indeed need ice nuclei.
Some companies manufacture pyrotechnic cloud seeding flares, which are then used by our governments and officials for hail suppression, rain enhancement and snow pack augmentation.
Some climate intervention studies suggest a potential cooling effect of deliberately perturbed cirrus, but at the risk of modifying precipitation inadvertently.
Climate engineering, the intentional alteration of Earth’s climate is true and nobody knows where it will end. The practice of cloud seeding goes back to the 1940s, and originally arose as a means to dissipate severe storms or produce precipitation. However, cirrus cloud seeding is different from the traditional cloud seeding in many respects: the targeted clouds, the involved microphysical mechanisms and its very intention, which is to modify climate rather than weather.
