Earth's normal temperature cycles happen over periods of thousands of years.

We are observing a warming over a period of 50 years at a rate that does not match that of a normal/natural slowly evolving temperature change.


The CO2 hypothesis is unproven,

Do you refuse to admit that they have proven that CO2 and other gases act as a "greenhouse" effect by absolbing infrared instead of letting it through ?

If you accept that in a lab that CO2 has this effect on a small scale, why do you refuse to admit that it would also have a similar effect on a planetary scale ?
