Saariselän avaruussääkonferenssi: Auringon rooli jopa 50%
Linkki Space Climate Symposium Saariselällä
"The recently completed Space Climate Symposium held in Finland came to some rather interesting conclusions regarding the solar contribution to 20th century climate change. Averaged over the entire globe the consensus (for what it's worth) was that solar variability contributed only 10-20% of the temperature variations observed, although some said it was 50%. But many agreed that solar variability can have a very strong regional effect - in fact stronger than any anthropogenic signal, especially over North America, Europe and Siberia. That's a substantial area of the northern hemisphere and, as we know, the recent warming spell has been somewhat stronger in the northern hemisphere and that's where the vast majority of the temperature sensors are".
