Paraphrasing Richard Feynman: Regardless of how many experts believe it or how many organizations concur, if it doesn’t agree with observation, it’s wrong.
The IPCC, some politicians and many others in the ‘consensus’ stubbornly continue to proclaim that increased atmospheric carbon dioxide (CO2) was the primary cause of global warming. Measurements demonstrate that they are wrong.
Some of their mistakes were discussed more than two years ago Mistakes made by the Consensus - climaterealists.com. The atmospheric carbon dioxide level has now increased since 2001 by an amount equal to 25.9% of the increase that took place from 1800 to 2001 (1800, 281.6 ppmv; 2001, 371.13 ppmv; Sept, 2012, 393.35 ppmv). The temperature trend, which was declining through 2009, was raised to flat through 2011 by the El Nino that peaked in March, 2010.
That is the observation. The average global temperature trend since 2001 is flat. No amount of spin can rationalize that the temperature increase to 2001 was caused by CO2 increase but that 25.9% additional CO2 increase had no effect on the average global temperature trend after 2001.
Without human caused global warming there can be no human caused climate change
Melting Ice Delusion
The Warmers’ perceptions were reinforced when more artic ice than usual melted this Northern Hemisphere summer.
With all else equal, ice melts when the surrounding water becomes warmer than it was when the water froze. The observation that more arctic ice than usual melted during the 2012 Northern Hemisphere summer is evidence that warmer water temporarily got to the Arctic Ocean but says nothing about whether or not the planet is still warming.

The planet has warmed about 8°C since the end of the last glaciation (about 16,000 years ago) when ice was over a mile thick in present day Minnesota and the continental shelf was dry land. Ice has continued to melt, off and on, and it has been warming more or less regularly since the depths of the Little Ice Age (about 400 years ago). It stopped getting warmer in about 2001. The assertion that it is warmer at the end of a warming period is, to be charitable, not very profound.
That the continental US, which occupies less than 2% of the planet surface, experienced a heat wave also does not mean that the planet is still warming.
