No, each statement is not referenced; many in fact are not. I see that in the effects of climate change on plant biodiversity, "effects on temperature" subsection has some non-cited information on increase of temperature effecting the rates of photosynthesis and I can add some biochemical and ecological perspective to that.

The articles are generally neutral without any distracting information.

Most, if not all of the sources are from reliable journals, such as Nature.

The links that I clicked did work correctly.

The effects of water and temperature on physiological responses leading to a decrease in biodiversity, are underrepresented, which is why I added to it.

The information seems current. Most of the sources are from 2000-2010, which is fairly current for climate change although it will need changes soon.

It's good for this to be semi protected because there are a lot of organizations that will deny climate change or attempt to delete the contents or mock it.

Yes, they mentioned climate change, because that was the title of the page and it's effects on plant biodiversity.
