I'll post this for the third time because it is so significant:
A new 650,000-year record
"One of the most important things is we can put current levels of carbon dioxide and methane into a long-term context," said project leader Thomas Stocker from the University of Bern, Switzerland.
"We find that CO2 is about 30% higher than at any time, and methane 130% higher than at any time; and the rates of increase are absolutely exceptional: for CO2, 200 times faster than at any time in the last 650,000 years."
You have your ice core data and I have mine.
To simplify, mine came from Greenland and the temperature chart looks like this:
Wait! The current day temperatures were reached 10,000 years ago. And look at that jump!
I believe Duke said something about regional differences?
Or maybe it has to do with the fact that temperature is reconstructed by analyzing the amount of oxygen found in the ice core. Why didn't BBC mention the oxygen levels or even just temperature levels since that seems to be measurable?
And BTW, global warming skeptics gleefully jumped on the claims of two guys that the so-called "hockey stick" chart showing the rapid rise of global temperatures in the last part of the 20th century was flawed.
Well, not so fast, FOXNews fans. Turns out it may be not so flawed after all:
Global-Warming Skeptics Under Fire
The jury is still out on this, apparently, but those who frantically tried to write it off may have to curb their enthusiasm for a while. Even if the chart has to be slightly revised, do you, once again, attribute the far-more-rapid temperature rise to coincidence?
Old news, but why did Dr. Michael Mann, who originated this hockey stick graph, refuse to release his data for years? Could it be what makes the math seem fuzzy? That seems suspicious and after Congressman Barton demanded his data he finally released it.
The problem is not with the math, although some tried that angle. The problem is two things. One, the data is derived from tree rings. Tree rings are a poor test of temperature considering that tree rings are affected by more than just temperature.
Second, some of his data was insufficient to be considered statistically significant. For instance, the entire 15th century was judged by one tree ring.
The math is irrelevant when your data is bad.
And how do you explain the arctic ice, glacier recession, slowing of the Gulf Stream, and increased sea temperature? Or are those naturally-occurring events that just happened to coincide with 20th-century human activity, once again purely by chance?
Is it all attributable to coincidence?
Or is there a possibility that there is a cycle? Were those glaciers always there? There used to be a glacier where I am sitting right now, and at one time an ocean. The glaciers receded suspiciously as mammals formed and took hold as a dominant species. Perhaps they farted too much and filled the atmosphere with methane.
By the way, never trust any data that uses the word "likely" as fact. It really means, "we think so but can't prove it."
