AlGore said we were all going to die in 10 years......that was 11 years ago. Right before he got in his private jet and his mansions that are heated and air conditioned year around.
No he didn't.
Here's the actual proof:
You can obtain the seasonal temperatures back 10,000 years from taking ice core samples at the poles.
The % of dissolved oxygen isotopes correlate with the atmospheric temperatures.
There is a pretty consistent seasonal swing for 99% ( 9900 years) of temp and normal climatic variation.
Please note, that the levels of dissolved CO2 stayed steady during this 9900 period.
This is significant, because we don't see a significant rise in CO2 until the industrial age at just over 100 years ago.
BUT, over the last 120 years, the amount of CO2 gas has greatly increased.
Since CO2 ( carbon dioxide) amounts are only fraction of a %, any change is significant.
Simply plot a graph with CO2 levels vs polar temp and it's obvious.
The linear regression line fits damn near perfectly with the data.
This is objective proof of a causal relationship within the physical sciences.
