Lead Section
The lead section contains a sentence that properly defines the Keeling curve and then goes on to explain it. I like your definition for the Keeling curve, but your lead sentence seems a little big stringy to me, and I wonder if it might be better to split it up into two separate sentences.

Structure
There is some structuring present in the original article, but I don’t know if it is the best way to structure the topic. Currently, there are two sections: the lead section and a “Mauna Loa Measurements” section. While the Mauna Loa observations are important, there is a fair amount of content in that section that doesn’t really have to do with Mauna Loa. I would probably split that section up. In addition, I would create a separate general history section, which would combine some material from the introduction paragraph with some parts of the Mauna Loa section.

Balance of Coverage
Carbon dioxide is one of those topics that can get contentious on the internet. However, I don’t see anything in the original article that comes across as excessively opinionated. The article is simply stating the facts that are presented in the peer-reviewed journals. In addition, the article is good with sticking to the topic of carbon dioxide concentrations, and not getting into a climate-change debate.

Neutral Content
Overall, both the article and the content in your sandbox are pretty neutral. However, the part about Keeling’s son in your sandbox seems to be a little bit one-sided, although it is important. Maybe you could rephrase it slightly to make it appear more neutral.
