Proxies are information recorders that we use to give us insight as to what the earth was like in the past. Some common proxies include fossils, ice cores, tree rings, isotopes, ect.

Overall, the page talking about Climate Proxies looked good, but there were some issues that I found.

The references used to support the facts within the Wikipedia page were relevant and reputable. The page itself and the material contained within it pertained to Climate Proxies and how the information was related to the overall topic. The page was neutral in tone and presented facts, rather than trying to persuade a reader. Most of the information used came from news sources, published scientific works, as well as sources that provide definitions for the words that may be harder to understand for some readers. Within the page, the length of the Boreholes section is the longest compared to the other examples of proxies which combined together add to the length of the Borehole section. However, the "Fossil Leaves" section is a new science, so information may be limited for now. Most of the source links do work, however with a few exceptions of "Page not found" or redirections to the main source rather than the material used on the Wikipedia page. When it comes to the page being locked, it is not. This allows for changes to be live and be seen by someone who is not logged in to Wikipedia. As a result of the lack of locking the page, anyone can make an edit and not have administrators review revisions. When it comes to the freshness of evidence used, most of the information was cited eight years ago and said evidence was either not dated on the source page itself or was published within the early 2000's.

Varves are different particles that accumulate over time with many layers. Scientists see different compositions of layers due to the difference in water flow between spring and winter.

I think that this article is very well written and explains what the subject of interest is In a way that anyone could understands. It does a good job explaining how this proxy was used for the past and how it tells us about the past. Based on what we have mentioned in lecture, during the winters, trees freeze and then thaw in the spring. This gives them their rings and this behavior closely resembles varves. What makes varves different however deals with rocks. The data scientists collect using this proxy is used to look at what has layered over time, but throughout history, scientists have tried to relate varves around the world like they do with fossils, but they cannot assume this because it is different for each place and too inconsistent. By looking at the layers we see what was there before, but its limited to it's location. The peer reviewed articles are current, but there are some out of date ones, but all are appropriate.
