Just out of curiosity, are you stating that climate science is wrong because.. a video on youtube said something about CO2-levels?

You had a quote about the CO2 amount in the jurassic period, but according to the information available it seems that the average temperature was 3 celsius degrees higher than it is nowadays. Doesn't it sound like CO2 would have a strong link to the temperatures?

Also there's an interesting graph about CO2 and temperatures in the past.
