Why do sun spots increase temperatures on Earth?
« on: 28/02/2011 20:30:03 »
Paul Young  asked the Naked Scientists:

Paul from Surrey.

I read recently that  Sun Spots are the coldest part of the sun and every 11 years they reach their  maximum in number.  However this is accompanied by warmer temperatures on the  Earth.  When Sun Spots are less in number then the Earth is colder.

My question is if  Sun Spots are cold parts of the sun then why does having more of them increase temperatures on the Earth?

Thanks for your help,


What do you think?

Sunspots are also assocated with solar flares and coronal mass ejections which can affect the earth's atmosphere and these are the processes that cause the raised temperatures. also they may be dark and cool in contrast to the normal sun but they are not all that much cooler than the rest of the surface of the sun
