“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.”

“It seems that, notwithstanding the dramatic increases in manmade CO2 emissions over the last decade, the world's warming has stopped.”

Tony Abbott (1957) Australian politician

“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.”

“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 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.”

“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?”

“This goes back to the reason why alarmists abandoned the "global warming" term in favor of climate change. They can play this bait and switch, showing changes in climate (which always exist) and then blaming them on CO2. But there is no mechanism ever proposed by anyone where CO2 can change the climate directly without going through the intermediate step of warming. If climate is changing but we are not seeing warming, then the change can't be due to CO2.”

“That the emission of light must waste the sun, is not a difficulty that can be opposed to our hypothesis.”

William Herschel (1738–1822) German-born British astronomer, technical expert, and composer

Source: Sir William Herschel: His Life and Works (1880), Ch.4 "Life and Works" quote from his paper "Nature and Construction of the Sun and Fixed Stars" (1795).
Context: That the emission of light must waste the sun, is not a difficulty that can be opposed to our hypothesis. Many of the operations of Nature are carried on in her great laboratory which we cannot comprehend. Perhaps the many telescopic comets may restore to the sun what is lost by the emission of light.<!-- p. 148

“I'm not a global warming believer. I'm not a global warming denier. I'm a global warming agnostic who believes instinctively that it can't be very good to pump lots of CO2 into the atmosphere but is equally convinced that those who presume to know exactly where that leads are talking through their hats.”

“CO2 is far from being the biggest greenhouse gas. Chloroflourocarbons (CFC's) commonly used as refrigerants [are] far worse. Of naturally created GHG's, Methane is 23 times more effective at warming the atmosphere than CO2. Nitrous Oxide is even worse at 296. So far no emergency legislation has been authored to eliminate the effect of cows or dental surgeons.”
