From the article
"It's been at least 800,000 years - probably more - since Earth saw carbon dioxide levels in the 400s, Butler and other climate scientists said."
You can't have it both ways. Remember the Nature article on the rise of CO2 at the end of the last glacial termination. That research said that the ice core data did not represent 'global data'.
But here again is the same old tune that the antarctic ice core data does represent global data.
The article does state that CO2 is not equally distributed throughout the atmosphere. And that the arctic is where the ppm values are highest, except for the 'urban' areas. And then compares the arctic data to the antarctic ice core data.
Here's some temp records from the arctic.

There's a law for them and a law for us, nothing new.
