The Greenhouse effect does not exist...

Through a series of controlled experiments, I demonstrate that the warming effect in a real greenhouse is not due to longwave infrared radiation trapped inside the greenhouse, but to the blockage of convective heat transfer with the surroundings, as proven by Professor Wood in his 1909 experiment.
Read more at link above for all six experiments.

The greenhouse effect inside greenhouses is due to the blockage of convective heat transfer with the environment and it is not related, neither obeys, to any kind of “trapped” radiation. Therefore, the greenhouse effect does not exist as it is described in many didactic books and articles.
The experiment performed by Prof. Robert W. Wood in 1909 is absolutely valid and systematically repeatable.

Clouds act as a negative feedback and cause significant cooling

A new paper published in Geophysical Research Letters (as reported by The Hockey Schtick)

A paper published today in the Journal of Geophysical Research finds that a natural atmospheric oscillation, the Southern Annular Mode, is correlated to significant increases in cloud cover resulting in "large scale" local cooling of approximately -2.5C. All climate models falsely assume clouds result in net positive feedback and increased temperatures, however this new paper and several others show clouds instead result in net negative feedback and cooling.
Key Points
  • Sudden regional increases in cloud cover are detected over S. America
  • Changes linked to the Southern Annular Mode
  • The cloud changes are associated with regional temperature reductions

Global Warming vs Heat Waves

Real Science reports:

Heatwaves Were Much Worse Through Most Of US History

Michelle Malkin in the Nation Review writes:

Only You Can Exploit Forest Fires
Global-warming blame-ologists ignore the hard truths.

Al Gore slithered out of the political morgue to bemoan nationwide heat records and pimp his new “Climate Reality Project,” which blames global warming for the wildfire outbreak. NBC meteorologist Doug Kammerer asserted: “If we did not have global warming, we wouldn’t see this.” Agriculture Department undersecretary Harris Sherman, who oversees the Forest Service, claimed to the Washington Post: “The climate is changing, and these fires are a very strong indicator of that.”
And the Associated Press (or rather, the Activist Press) lit the fear-mongering torch with an eco-propaganda piece titled “U.S. summer is what ‘global warming will look like.’”
The problem is that the actual conclusions of scientists included in the AP’s screed don’t back up the apocalyptic headline. 
From Dr Roy Spencer:

June 2012 U.S. Temperatures: Not That Remarkable

I know that many journalists who lived through the recent heat wave in the East think the event somehow validates global warming theory, but I’m sorry: It’s summer. Heat waves happen. Sure, many high temperature records were broken, but records are always being broken. 

“But, Roy, the heat wave is consistent with climate model predictions!”. Yeah, well, it’s also consistent with natural weather variability. So, take your pick.
