Overview: It has long been widely accepted that the sun is absolutely critical to all weather and climate here on Earth and yet there are still some aspects of this connection that are not too well understood and even controversial.
For example, there has been the belief by many atmospheric scientists that cosmic rays which penetrate the Earth’s atmosphere from outer space can play a significant role in the formation of clouds which, in turn, has a direct impact on climate. Solar activity has a direct impact on the ability of cosmic rays to actually reach the Earth’s atmosphere. A just published study has confirmed the notion that cosmic rays can indeed be an important player in Earth’s weather and climate and the role of the sun is critical.
