This is the final repost in my little walk down memory lane, in honor of the Paris Climate Conference, (well and also for my pal AL with his gross misunderstanding of what science and the human learning process is all about. This was originally posted at my Citizenschallenge Blog over four years ago. It is a bit out of date, still the information it holds has been reaffirmed with each succeeding year - despite the fact that the Republican/libertarian community refuse to recognize or consider any of it.

I've done this because the way the contrarian community has bastardized the notion of expert consensus. This information becomes more important with every new unreasoned politically motivated attack on science we witness. Thus, it is worth considering in more detail, and that's why I've brought it up at a couple discussion boards, now I've got this collection of supporting documentation to point to.
Scientific Consensus on Global Warming
http://www.ucsusa.org/ssi/climate-change/scientific-consensus-on.html
Scientific societies and scientists have released statements and studies showing the growing consensus on climate change science.
A common objection to taking action to reduce our heat-trapping emissions has been uncertainty within the scientific community on whether or not global warming is happening and if it is caused by humans. However, there is now an overwhelming scientific consensus that global warming is indeed happening and humans are contributing to it. Below are links to documents and statements attesting to this consensus.
