AGW Observer

Observations of anthropogenic global warming


This blog is about climate science with an emphasis on the observational side. Although climate science will be explored also more generally here, the emphasis is on the issues relating to the ongoing climate change. The AGW in the title stands for Anthropogenic Global Warming, which is a commonly used term for the current human-caused climate change.

I am not a professional climate scientist, but just an interested layman who has been getting familiar particularly to the observational side of the issue by reading the research papers on the subject. I hope I can offer some relevant information on the subject especially as the public discussion on the subject tends to focus more on what climate models can do instead of emphasizing the observational body of evidence which is very large and in my opinion convincing by itself even without far-reaching climate theories or models (which is not to say that climate models are not important and useful tools – they are).

    Dear Ari, I have once tried to establish a similar collection of papers (including abstracts and PDF links) at the German Wikiversity. Though I didn’t keep it updated after some time, you might find some of the lists interesting and maybe want to copy+paste them here. The collection can be found at , and while it is in German all abstracts are of course in English, so you should not have a hard time looking for useful stuff. Cheers, Nils

    Yes, there seems to be many papers I think I’ll add to my lists, thank you.

    What are the sources of the CO2 isotopes C13 and C14?

    Hi John,

    That’s a good question. I’ll answer it in the “papers on anthropogenic carbon dioxide observations”:

    That is a list of papers dealing with issues relating to your question, and I would like to keep this “about” page free from comments (I though I had locked comments for this page but apparently not :) ).
