Nobody has brought them up here, but they have been mentioned on the internet many, many times. Generally they’ve been cited as good evidence for the link between carbon dioxide and temperature - just like climate scientists predicted!
On the other hand the existence of natural changes, the very largest of which are drops of about 100 ppm over the course of tens of thousands of years, does not speak much to the origin of the current rise, which is surpassing that in maybe 1-2% the time. Anyone who proposes it can be accounted for by variations as seen in Vostok is either ignorant of the vast difference in scale, or hoping their audience is.
By the way, are you going to comment on your nonsense here, or are you hoping we’ve forgotten? Because it’s only been a day.
