Another Nail In the Global Warming Coffin

Most of this is not new. The fact that the Earth’s climate has changed many times over the millennia for reasons that are not understood, and that the Earth’s climate history is replete with periods that were warmer than what we are experiencing now, has long been known. What is noteworthy, I think, is that a government agency is willing to say out loud what skeptics have been saying for years. 

  Power Line (powerlineblog.com)   "Statistics Norway, the government agency that produces official statistics for that country, released a report last month titled “To what extent are temperature levels changing due to greenhouse gas emissions?” The report concludes:

[T]he results imply that the effect of man-made CO2 emissions does not appear to be sufficiently strong to cause systematic changes in the pattern of the temperature fluctuations. In other words, our analysis indicates that with the current level of knowledge, it seems impossible to determine how much of the temperature increase is due to emissions of CO2.

"The report looks at the last 400,000+ years of Earth’s climate history:

The preceding four interglacial periods are seen at about 125,000, 280,000, 325,000 and 415,000 years before now, with much longer glacial periods in between. All four previous interglacial periods are seen to be warmer than the present. The typical length of a glacial period is about 100,000 years, while an interglacial period typically lasts for about 10-15,000 years. The present inter-glacial period has now lasted about 11,600 years.

 "So sometime relatively soon, the Earth is going to start getting really, really cold. This accompanying chart shows that history, based on ice cores:
