冰和云的微水滴需要有催化种子才会开始生长。它们可以是矿物质颗粒或者甚至是细菌,有些研究人员暗示,宇宙射线可能参与了这一过程。他们声称,当更多来自太空的这些高能粒子碰撞大气时就会形成更多的云层,其结果将对我们的气候产生深远的影响。位于瑞士日内瓦附近的欧洲核子研究中心(CERN)去年进 Micro-droplets of ice and clouds require catalytic seeds to begin growing. They can be mineral particles or even bacteria, and some researchers have suggested that cosmic rays might be involved in the process. They claim that as more of these energetic particles from space collide with the atmosphere, more clouds will form and the result will have a profound impact on our climate.
