There are so many factor on why we are seeing a "blip" in temperature. Angle of the Earth to the sun, orbital distance from the sun, coupled w/ we have had natural events that have expelled millions of tons of CO2, and man made.
The point I make is none of these scientist know what the cause is. It all a hypothesis but we have to take it as fact. Would I love to live in a TRULY carbon neutral man made environment. But thats not remotely possible at this time.
Also left off orbit and angle to the sun, but hey you know everything... But you want to go simple and blame to gasses but not look into other causes... Good job.
