I saw Joe Romm's new project to post clear and simple overviews of the basics of climate science at climateprogress.org: Launching the Climate Science Project (with your help)
Seeing his appeal for suggestions, I chimed in with a few pointers off the top of my head. This got in as comment #28 of 50 posted in the first day.
As I commented on climateprogress, I first learned of the new e-journal "WIREs Climate Change" from Wiley Interscience, thanks to this Science Daily item). Here, I'll just restate my point that ScienceDaily does a great job covering climate science news (along with lots of other fields.)
So I went to add this new WIREs Climate Change title into my list of climate-related journals. While I was at it, I updated that list a bit, adding categories for the long list of unranked journals. I grouped several of them coarsely under "paleo", "glaciology and polar", "oceanography and ocean-atmosphere interactions", and "other" (sorry, 'others' - nothing personal!)
I've had a quick look at the premier issue of WIREs Climate Change (WCC for short?) and it looks promising. It's a review journal, meaning the articles can be longer (10-12 pg. in the print edition) and give more background/basics than a typical journal paper. This first issue is open access currently.
The articles by Judith Lean on "Cycles and trends in solar irradiance and climate" and David Parker on "Urban heat island effects on estimates of observed climate change" both look worth reading and perhaps recommending on the web.
I'm also looking forward to checking out some other titles from this issue including two on science communications.
Other useful-looking bits I found on the web today:
Terrain.org essay on Ocean acidification - a greater threat than climate change or overfishing?
The UK Royal Meteorological Society homepage has several interesting looking links, including one to the above-mentioned WIREs, but with a flashier animated gif link, thus:
Finally, I'm also intrigued by their link to a new resource for middle school teachers called Climate4classrooms This one has just a static gif for the link, but at least it's a preview:
Sadly the site itself appears to be 'broken' (saying 'Your database appears to be turned off' - should I make that, 'just not quite done yet'?) They do say it is just launching, so perhaps growing pains. Check them out if they do come online.
[Update 2010-03-05 - Climate4Classrooms is online and working now. Do check it out if you're involved in teaching or just want to see ways to present climate science at a level for kids.]
