The climate stubbornly refuses to co-operate with computer models and the writers of alarmist popular articles and books. - Ian Plimer

If CO2 derived from modern industrialisation is the culprit for global warming, then why did the global temperature increase from 1918 to 1940, decrease from 1940 to 1976, increase from 1976 to 1998 and decrease from 1998 to the present?

If we do not understand the cause or causes for the biggest climate change of all time, what hope have we of understanding modern climate change?

The hypothesis that human emissions of CO2 can create global warming can be tested by measurement. … No warming has occured since 1998. … During that time atmospheric CO2 has increased. … The test of the hypothesis above shows that there is no relationship between measured temperature and CO2 emissions. The hypothesis fails.
