I believe that our presence here, on earth, in the numbers that we have managed to achieve, coupled with the fact that we have destroyed millions upon millions of oxygen producers (Trees) and have a penchant for asphalt and tarmac, which are very heat absorbing, and purposely keep reflective surfaces to a minimum (they're blinding) AND have created a civilization based on burning fossil fuels and using other things which are detrimental to our ecology, that, yes, we are probably responsible in large for the exelerated melting
of the global ice... but, we have been in a state of warming since the last ice age ended... we just speeded up the process.

The fact that our model does a surprisingly good job with simulating the last 400,000 years

Except that we do make an attempt to validate the model with respect to how it has performed against the best estimate
of global ice volume we have — Shackleton's 2000 record (I might add that I am not sure of any other modeling study that has tried to validate itself against the Shackleton record).
