Many sources are not properly cited..few citations for tree rings as proxies. Limited information on this topic as well.

One specific source, "Hot House," is overly cited. Lots of information on boreholes. Few citations about pollen grains.

Majority of the sources cited are not peer reviewed. Some peer reviewed articles appear in the reference list, but they are not the primary sources referenced in the article.

Uneven distribution of information. Some contents have lots of highly detailed, scientific information, while others have very surface level information. It is difficult to determine what sources are used to support each fact because citations appear sporadically, rather than after each fact. Some sources do not appear to be entirely reputable; these are the sources that are used most frequently in the article. The first source listed in the sources list does not have any references when i clicked on the link. Source 5 in the sources list is no longer available. The most reputable sources are government documents, rather than peer reviewed articles. The government documents are based on trying to spread accurate data and informed decision making. News articles from CNN are referenced but clicking on the link would only bring me to the CNN webpage, not the specific article.
