yes, we have a long term chart - that you posted - that shows a cooling stratosphere, as expected by climate science - apart from that bit at the end, during which your chart shows the cooling trend has flattened off. Which I've pointed out could be explained by ozone recovery.
presuming I've understood tristanc's post correctly, he points out that the chart you used may be incorrectly showing a flattening off, due to it effectively indicating both upper troposphere and lower stratosphere results.
So? There are two possible explanations for your chart. Neither of which requires anybody to jump to the conclusion you have - that climate change science is wrong. Climate scientists certainly have not jumped to that conclusion.
Again: you create a straw man, go nuts, and think you've proven climate science wrong.
