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?

To argue that human emissions of CO2 are forcing global warming requires all the known, and possibly chaotic, mechanisms of natural global warming to be critically analysed and dismissed. This has not even been attempted.

Mars, Triton, Pluto and Jupiter all show global warming. Climate changes on other planets and their moons show that climate change elsewhere in the Solar System could not possibly be due to human activity on Earth. There must be a driving force outside the Earth. It is the Sun.
