Can you provide a reputable source for this? By which I mean a link to an original scientific paper or serious science website such as Nature for example.
There is a clear link showing that CO2 levels population growth and fossil fuel burning all occurred at the same time and that during this time global temperatures have increased.
This image was lifted from Wikepedia, not always the most accurate source but I have seen graphs showing the correlation between CO2, population, temperature and fossil fuel usage in journals such as Nature: Climate Change in the past.
This could be a coincidence but seems unlikely. It is true to say that correlation and causation are separate things however but I believe that this does raise important questions.
I will reply in more detail once I have had time to locate relevant sources
There may not be a link but on the one hand if we are causing the climate to change and we take appropriate action we limit the effects. If non of this is from human causes what have we lost by taking action?
