The sun seems to actually be quite a bit more restless than it has been for quite some time, well for about 100 years or so. This is according to Swiss Astronomers at the Insitute of Astronomy of the Surich Technical University. Dr Sami Solanki who led the study looking at historical records ranging from sunspot records back to the year 1610 and compared this with radioactive isotopes in ice that change depending on the activity of the sun. His team discovered that there has been a steady increase in the number of sun spots especially over the last 60 years. It is thought that this sun activity may be acting togther with human fossil fuel burning to increase the average temperature on Earth. The exact way this happens is not entirely certain. |
 The sun is more active than ever and could be part of the recent warmer weather. |
