So, can I get my incandescent bulbs back now?

This is actually the second recent story on the issue. I haven't gotten around to linking the first yet, but I'll do it down below.

First, the news out of NASA.

New NASA Data Blow Gaping Hole In Global Warming Alarmism
NASA satellite data from the years 2000 through 2011 show the Earth's atmosphere is allowing far more heat to be released into space than alarmist computer models have predicted, reports a new study in the peer-reviewed science journal Remote Sensing. The study indicates far less future global warming will occur than United Nations computer models have predicted, and supports prior studies indicating increases in atmospheric carbon dioxide trap far less heat than alarmists have claimed.

...

"The satellite observations suggest there is much more energy lost to space during and after warming than the climate models show," Spencer said in a July 26 University of Alabama press release. "There is a huge discrepancy between the data and the forecasts that is especially big over the oceans."

...

The new NASA Terra satellite data are consistent with long-term NOAA and NASA data indicating atmospheric humidity and cirrus clouds are not increasing in the manner predicted by alarmist computer models. The Terra satellite data also support data collected by NASA's ERBS satellite showing far more longwave radiation (and thus, heat) escaped into space between 1985 and 1999 than alarmist computer models had predicted. Together, the NASA ERBS and Terra satellite data show that for 25 years and counting, carbon dioxide emissions have directly and indirectly trapped far less heat than alarmist computer models have predicted.

In short, the central premise of alarmist global warming theory is that carbon dioxide emissions should be directly and indirectly trapping a certain amount of heat in the earth's atmosphere and preventing it from escaping into space. Real-world measurements, however, show far less heat is being trapped in the earth's atmosphere than the alarmist computer models predict, and far more heat is escaping into space than the alarmist computer models predict.

Secondly, from a week or so ago, the news out of CERN. To provide some context for it, we look back to 1998, when the experiment was proposed:
A controversial theory proposing that cosmic rays are responsible for global warming is to be put to the test at CERN, the European laboratory for particle physics. Put forward two years ago by two Danish scientists, Henrik Svensmark and Eigil Friis-Christensen, the theory suggests that it is changes in the Sun's magnetic field, and not the emission of greenhouse gases, that has led to recent rises in global temperatures.
(We all remember 1998, right? The hottest year in the history of the world [since record-keeping started all of 100 years earlier]...)

So, they did their experiment, got results, and were promptly warned not to talk about them...
The chief of the world's leading physics lab at CERN in Geneva has prohibited scientists from drawing conclusions from a major experiment. The CLOUD ("Cosmics Leaving Outdoor Droplets") experiment examines the role that energetic particles from deep space play in cloud formation. CLOUD uses CERN's proton synchrotron to examine nucleation.

...

The CLOUD experiment builds on earlier experiments by Danish physicist Henrik Svensmark, who demonstrated that cosmic rays provide a seed for clouds. Tiny changes in the earth's cloud cover could account for variations in temperature of several degrees. The amount of Ultra Fine Condensation Nuclei (UFCN) material depends on the quantity of the background drizzle of rays, which varies depending on the strength of the sun's magnetic field and the strength of the Earth's magnetic field.

But how much? Speaking at a private event attended by El Reg earlier this year, Svensmark, who has nothing to do with CLOUD, wouldn't be drawn. He said he thought it was one of four significant factors: man-made factors, volcanoes, a "regime shift" in the mid-'70s, and cosmic rays.

The quantity of cosmic rays therefore has an influence on climate, but this isn't factored into the IPCC's "consensus" science at all.
Points to draw from these stories:
  1. The science is not settled.
  2. The models aren't good enough to justify a plane trip across the ocean, never mind crippling restrictions and restructuring of the world's economies.
  3. "Climate change denier" is not synonymous with "flat-earther," and definitely not with the much more pejorative "holocaust denier."

So let me share my position again, at least in the short form:
It is a reasonable hypothesis to suppose that there is a relationship between increased CO2 levels and increased temperature on a global level. This hypothesis has not been proven to my satisfaction. I do not believe that the scientific "consensus" is as strong as the warming alarmists would have us believe.
...
Many of the people favoring what may objectively be looked at as anti-Western civilization, "spread the wealth to the poor" policies with regards to carbon have a history of favoring anti-Western civilization, "spread the wealth to the poor" policies at other times in history, for other reasons. Many of the people who are pushing the AGW story the hardest have profited, are profiting, and can be expected to continue profiting from policies and government outlays that are based on their assumptions of short-term climate catastrophe. Many of the people who are profiting from the climate change storyline are living their lives as if it weren't a problem.
...
If you kludge a model with fixed data-specific adjustments to say what you want it to say every time you get new data, as they did at CRU, you can always make it match. A model which matches new data based on kludging it after that data is known, has no useful predictive power for future events...The CRU model was garbage, and it was fed garbage. I would not gamble a nickel based on the output of the CRU model.
...
It is difficult to believe that engaging in economically destructive activities based on the output of a fudged model using an uncertain and non-reproducible data set is a rational course of action.
So, I ask again - can I get my incandescent light bulbs back now?
