It is the sun that is causing the current warming since temps on both Mars and Neptune have been rising.

Very interesting. If the temperature on other planets is rising in parallel with earth, that would be very convincing for the sun being the cause. Could you supply a reference for this?

Can't find it now, but Mercury's surface temperature was also repoted to be on the rise, perhaps someone has a link.
