Ok getbiggers here's the data in support of CO2 levels causing an increase of global temps :
The poles are used because they have undisturbed ice samples and show the greatest amount of change.
1. Take a variety of ice core samples from the poles.
2. Analysis of the dissolved gases in the ice can be obtained, going back 10,000 yrs
a. The levels of CO2 show fairly normal seasonal cycles for the first 9900 years.
b. The temp is obtained by measuring the % of oxygen isotopes. The % of the common O2 isotopes correlates with temp. In the past 100 yrs the AVERAGE temp per season/per decade has increased.
c. Plot the variables of CO2 levels vs temp increase and use a linear regression analysis and you get a near perfect , statistical fit on the graph, in support of the trend.
This kind of evidence is the gold standard in real scientific research.
The real problem is that most people are ignorant of how climate change is actually measured and analyzed.
I don't want to sound pompous, but, the proof or evidence most use to deny this is fairly juvenile and pseudo science.
Wow, such an important-sounding post...and yet, so lacking.
The central theme of alarmism is that higher CO2 causes higher temps. Congrats, you've just plotted one of the two needed metrics, screamed "shup up!" And run away.
Where is the required plot of temperatures during this period, to prove higher CO2 causes higher temps? You DO remember the "higher temperature" part, right? You guys are always shifting your goalposts around, so it's possible you've forgotten your central "theory"
I love how you hand-wave your temperatures with words like "correlates" and "average" as if either of these bullshit, sophomoric statistical derivations can replace the real "gold standard", OBSERVATION. Since correlation between higher CO2 levels and temperatures is you THESIS, how can you state that as PROOF? It's imbecilic.
And the OBSERVATIONAL temperature studies have shown that the earth is not warming, and hasn't been since 1997.
So run along now and get ready to move your goalposts again. I am sure you'll find something to "prove" your "theories" enough for the NY Times to write another of their yearly breathless hagiographies: "This Time They've Done It!"
I'll be back then to dismantle that BS.
Toodles.
