Al Gore’s claim, drawn from climate “science,” that the Arctic would be ice-free by 2013 stands as a glowing symbol of the absurdity of climate change. Is there any other scientific discipline that makes false predictions 99% of the time?..
Just asking....
Being keen (!?) I located the Vostok data once. The samples are taken at quite sporadic intervals so I used some cubic spline interpolation to create a regular sampling interval and then compared the two time series in Excel. I got 900 years which, considering the amateur approach, I decided was near enough to a confirmation.
The mechanism that might make that a reality is the air heating the sea water. Most of the earth's available CO2 is in the oceans and warmer water holds less CO2 than cold water. So, as the water warms it gives off CO2. I guessed, without evidence, that the volume of water that needed heating was causing the lag.
