... those who are absolutely certain that the rise in temperatures is due solely to carbon dioxide have no scientific justification. It's pure guesswork.

— Henrik Svensmark

It's likely that CO2 has some warming effect, but real proof of that hypothesis is tricky. You have to confirm by observation exactly how…

The scientific facts indicate that all the temperature changes observed in the last 100 years were largely natural changes and were not caused by…

Few scientists now dispute that today's soaring levels of carbon dioxide and other gases in the atmosphere will cause global temperature averages to rise…

— Carl Sagan

“Why have global temperatures not risen in the best part of two decades while CO2 levels have kept on rising? •    ”

— Alan Carlin

The atmospheric CO2 concentration is rising - mainly due to the burning of fossil fuels. It's agreed that this build-up will, in itself, induce…

There is no proof that carbon dioxide is causing or precedes global warming....All indications are that the minor warming cycle finished in 2001 and…

— John Williams

It's not the case that carbon dioxide drives temperatures. When you leave Ice Ages, it's the other way around: The temperatures go up first,…

— Piers Corbyn

CO2 emissions have been increasing, but the rise in air temperature stopped around 2001. Climate change is due in large part to naturally occurring oscillations.
