I think everyone should be careful about reading too much into this graph. While it certainly shows some interesting variations, look at the SCALE of the variation.

It's from 387 to 402.5 PPM. The high end of the scale is only 4% higher than the low end of the scale. And don't forget that is parts per million: so the difference between the high and low ends of the scale is only 15.5 parts per million.

Perhaps that is because the CO2 disperses relatively quickly. But, I'd prefer to see more data, to see if the variations remain constant.

You are quite correct.
But i think that most of us on this forum are aware of the amount of Salt required for climate 'science'. :)

The Data is from NASA ,so it may soon be on their web site. I'm not expecting to see anything other than logical seasonal changes, to be honest.
