with 32 years of  rapidly increasing global temperatures and only a minor increase in  global co2 emissions, followed by 33 years of slowly cooling global  temperatures with rapid increases in global co2 emissions, it was  deceitful for the ipcc to make any claim that co2 emissions were  primarily responsible for observed 20th century global warming."
