If CO2 derived from modern industrialisation is the culprit for global warming, then why did the global temperature increase from 1918 to 1940, decre… - Ian Plimer

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.

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

Mars enjoys global warming yet has almost no atmosphere. To my knowledge, there is no industry or human emissions of CO2 on Mars. There is strong evidence that the Sun drives climate on Mars. The Sun is probably also the main driving force for climate on Earth.
