There is a huge debate about rising temperatures globally. Different scientific theories are exploring the mechanism behind it. This led to the emergence of cosmoclimatology theory. It was propounded by Danish physicist Henrik Svensmark over the alternative theory of anthropogenic CO2.
The theory argues that climate is controlled by low cloud cover over the earth. When this cloud cover spreads wide, it has a cooling effect by reflecting solar energy back into space and vice versa. These low clouds, in turn, are formed when subatomic particles called cosmic rays, emitted by exploding stars, combine with water vapour rising from the ocean. The constant bombardment of the planet by cosmic rays is modulated by solar winds. These blowing solar winds prevent cosmic rays from reaching the earth and creating low clouds. The solar winds in turn are caused by the varying sunspot activity of the sun. When sunspot activity decreases, we get global cooling.
