Global warming has no correlation to carbon dioxide levels

I AM most gratified that no one has been able to contradict the fact that carbon dioxide is not responsible for so-called global warming (letters April 9). I attach the temperature graph for the last 10 years. There are two sets: the Hadley Centre s surfa

I AM most gratified that no one has been able to contradict the fact that carbon dioxide is not responsible for so-called global warming (letters April 9).

I attach the temperature graph for the last 10 years. There are two sets: the Hadley Centre's surface temperatures plotted in magenta (tending to be over-estimates and less reliable) and the MSU satellite temperature readings in blue. There is no correlation at all with the rising CO2, shown in green.
