yep , just like that which is occurring in the rest of the solar system and has occurred thousands and millions of years before man was around , let alone the industrial revolution .
90% correct! When ALL the know cycles are taken into account - eg solar output, galactic oscillations etc, there is still warming over and above what we would expect the temperature to be.
SO FAR, the only variable found that can explain the current rise is CO2. There might be something we don't know about, such as some strange loss of expected cloud cover, but, the best and brightest have not found it.
