QUESTION:

Why would the first half doubling give 0.5ºC rise
while the second half doubling gives 3ºC or 6
times as much rise?

A single, snappy, and short answer would be,
"You said the system was nonlinear, didn't you?"
To break it down further, here are
TWO ANSWERS:

1) There is a delay between the application
of CO2 to the atmosphere and the rise of
global mean surface temperatures of about
half a century.

2) The rising CO2 levels trigger positive
feedbacks.

Consult any climatology text written in the
last decade, the IPCC documents, Google,
Wikipedia, or many other references for details.

Better yet,

Check with someone independent of the IPCC so you know they are not
politicall tied into their goal of wealth redistribution through this
phoney scheme:
