Ignoring the gratuitous insult, here's the NCA 2014 report (the report itself is about the impact of climate change; Chapter 2 lays out the case for climate change caused by humans. Citations are at the end of the chapter.): http://s3.amazonaws.com/nca2014/low/NCA3_Climate_Change_Impa...

There's also a web version where you can explore the highlights: http://nca2014.globalchange.gov/. The references are cited right there.

If you don't find this convincing, then I'd like to understand why. Also, if you don't trust this source (a US gov agency), I'd like to understand what kind of sources might you find more convincing.
