U.S. Climate Has Already Changed, Study Finds

http://www.nytimes.com/2014/05/07/science/earth/climate-change-report.html?_r=3

A very extensive report, known as the National Climate Assessment, was released earlier this week. Nothing in the report is particularly surprising, but its presentation for the general public, here, is incredibly impressive. (Not all government website releases are a disaster!)

If hardcore technical reports aren't your thing, the highlights portion of the site breaks each section down as plainly as possible, is extensively cited, and makes no secret the level of uncertainty inherent in current findings. The site is really quite fantastic, and I would encourage anyone with genuine interest, skepticism, and/or curiosity in U.S. climate change to fuck around in it for a while. (Of course, if well-substantiated, easily digestible scientific communications aren't your thing, there's always this.)

Perhaps, the most poignant message arising from the report is summarized in this quote from the article:
I don't really consider myself a policy person so... what do?

Edit: Also of note is the high diversity of those involved. Largely scientists, of course, but representative of a wide swath of interests, including some oil companies.
