First assignment:
I looked over the "Effects of climate change on plant biodiversity" and "Regional effects of global warming" pages. Both pages included references to sources of information. Relevant wikipedia pages were mentioned where in-text citations were not used. Each source appeared to be reliable provider of information. There was a section on the plant biodiversity page that did not appear to reference material regarding the claims made about temperature. Previously used sources may have mentioned effects of temperature, but there were a few spots where in-text citations may have been useful. Material was presented in a neutral manner. Up to my knowledge, each page stated only the facts / information from reputable sources. The sources I checked were peer reviewed or government reports. The "Higher level changes" section on the effects of climate change on plant biodiversity appeared to be underrepresented. This is a fairly important topic and I don't think a couple sentences can fully explain it. I checked a few of the links on each page, each link brought me to the source of information. I did not find any plagiarism. Both pages, besides the climate change page, were fairly underrepresented. The talk page of the plant biodiversity page discussed addition of more content to add depth. Users were assisting with proper citation of images.
Due to the nature of discussion around climate change, I think it was a good idea to make the "Climate change" page semi-protected. A semi-protected page is protected against vandalism and content destruction. These types of pages cannot be edited by newly registered users and require administrator status to edit. The regional effects and plant biodiversity page were both ranked C-level.
