Climate Myth	What the Science Says
"Friis-Christensen and Lassen from 1991, shows that Northern Hemisphere land air temperature has been closely correlated with the 11-year sunspot cycle in the last 130 years." 18 August 2011 (Source)	The sun has not warmed since 1970 and so cannot be driving global warming.
"ocean cycles...have been driving the Earth's climate for 4.7 billion years and are still doing so." 18 August 2011 (Source)	The PDO shows no trend, and therefore the PDO is not responsible for the trend of global warming.
"The observed nighttime temperatures have experienced a higher warming trend than the daytime temperatures. But the greenhouse model predicts exactly the opposite. " 24 February 2011 (Source)	Greater warming at night than day is a signature of an increased greenhouse effect.
"the observed dependence of the warming trend on the latitude and altitude is totally different than one predicted by the greenhouse-dominated models (which predict the hot spot in the middle, among other wrong features)." 24 February 2011 (Source)	We see a clear "short-term hot spot" - there's various evidence for a "long-term hot spot".
"Even when we assume that the whole change of the global mean temperature in the HadCRUT3 record from 1850 is due to the rising CO2, and many papers above - and hundreds of others - argue that it's not the case and other effects have positively contributed to the temperature - regression implies that the climate sensitivity equals 1.66 °C." 24 February 2011 (Source)	This argument ignores the cooling effect of aerosols and the planet's thermal inertia.
"There's no scientific evidence whatsoever that the climate sensitivity exceeds 2 °C " 24 February 2011 (Source)	Net positive feedback is confirmed by many different lines of evidence.
"The outgoing heat was measured e.g. by the ERBE experiment and the relationship of this heat flux with the temperature increase was studied by Lindzen and Choi (2009). The resulting sensitivity coming from this paper was 0.5 °C, and even when various conceivable mutations of the methods have been tried later, the sensitivity remained well below 2 °C." 24 February 2011 (Source)	Lindzen and Choi’s paper is viewed as unacceptably flawed by other climate scientists.
"cosmic rays...have been driving the Earth's climate for 4.7 billion years and are still doing so." 24 February 2011 (Source)	Cosmic rays show no trend over the last 30 years & have had little impact on recent global warming.
"solar activity...have been driving the Earth's climate for 4.7 billion years and are still doing so." 24 February 2011 (Source)	In the last 35 years of global warming, sun and climate have been going in opposite directions
"The existence of the remaining 4+ billion skeptics in the world, including tens of thousands of science PhDs, is being denied." 24 February 2011 (Source)	97% of climate experts agree humans are causing global warming.
