This is an incorrect argument designed to distract attention
As usual you have to examine the numbers and they are hoping you will not do this
China uses 3.1 Tonnes of Carbon per head
India 1.0
USA 29
UK 15

Even if you take out the per head and take absolute values China just squeezes out the US by the barest of margins
Effectively the argument says to developing countries "you have to continue living in poor conditions so that we don't have to cut back"
Not only that but because so much of the goods we use in the west are produced in China we are effectively outsourcing our emissions to them!
The idea that the problem is in population growth also assumes that we are OK as we are and do not to reduce which is incorrect.
I'm assuming that the argument was also put that they're not even trying to cut back.
This is also untrue
China and India both signed up for Carbon reductions last year

I'm not getting drawn into the climate change debate in News any more though because you can show them all the facts and give them all the reasons you like.
They associate climate change with left wing politics and so the fingers just go in the ears and it's "Nah Nah Nah If I shout loud enough it won't be true"
