The connection between solar activity and global warming has been a contentious issue for a long time. The idea that cosmic rays create global cloud cover just doesn't seem to be working out; even the highest estimates of cloud cover variation caused by cosmic ray flux predict the effect to be very small. Now UK [...]

Scientists in the U.K. have reported evidence that further refutes one theory of global climate change.

In the heated debate over global warming, there is an opposing idea, called the cosmic ray theory, which contends that climate change is simply caused by cosmic rays coming from the sun.

Please: There is no statistically sound link between magnitude, or thermal flux changes measure in or near the Sun and global warming trends.
