So looks like we are barely 1/4 of the way there.

* That's an extremely remarkable claim. No where in the scientific literature is such a value entertained.
* At 412 ppmv, we've raised the planet's average surface temperature from, 58.0-F, to 59.8-F. The poles have gone up 3.96-F.
* By 2100, we're looking at a global average 62.86-F.
* There won't be a North Pole, except water.
* Antarctica will be ice-free.
Can you turn us onto a source for the 1,600 number? Perhaps it was a simple typographical error.
* At a 160ppmv increase = the 'doubling' of carbon, and the 3-C warming( 5.4-F ).
