"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?"

“Studies of the Earth's atmosphere tells us nothing about future climate. An understanding of climate requires an amalgamation of astronomy, solar physics, geology, geochronology, geochemistry, sedimentology, tectonics, paleontology, paleoecology, glaciology, climatology, meterology, oceanography, ecology, archaeology and history.”

“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.”

“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.”

“There were no CO2 emitting industries in the Medieval Warming. This natural warming event was greater than the Late 20th Century Warming, which we are told is due to human emissions of CO2.”

“It is naïve to think that a model can predict future events on the Earth. To try to predict the future based on just one variable in extraordinarily complex natural systems is folly.”
