A major new report  to be published by Geophysical Research Letters, concludes that global warming will accelerate so quickly in the next 5 years – 150% of the IPCC’s predictions – that it is “expected to silence global warming sceptics”.
What I find interesting is that the report acknowledges that all 4 of the following factors affect climate:
- Human influences
- The sun
- Volcanic activity
- El Niño, also called the “southern oscillation”
Whether or not the report is correct about the next 5 years, I think it is important that mainstream scientists are now admitting that climate is affected by the 3 natural conditions of the sun , volcanism and the southern oscillation, as well as human influences.
The study did not look at the affect of magnetic fields or cosmic particles  on the Earth’s climate. Future studies should examine these as well, to either rule them out as having an insignificant affect on climate, or else quantifying their impact.
