Very impressive set of resources you’ve put together. I think it’s time for me to make a donation to your site. Time is money and your one stop shopping saves me a lot…thanks for the nice work!
Additional information on AO and NAO can be found here: http://www.appinsys.com/GlobalWarming/AO_NAO.htm
What a fantastic dashboard of information. Thank You !!! This site has enlightened me since the first time I happened in from a comment posted on not very Skeptical Science a couple of years ago when my investigation of AGW began to get serious while attempts were made congressionally to Cap and Trade CO2. Your site has provided so many sources of information to much of the thinking occurring on this topic. These reference pages are so informative and provide so many real time rebuttals to the many wild alarmists claims of CO2 signatures in weather events.
Looking for info as far as what forcing mechanisms might influence the fall and winter formation of the Pna index as models currently are in great disagreement.
A lot of colorful pictures, a lot of links. Brownie point score 100! But what the [SNIP: Language -REP] are the conclusion of all that ??
Thnaks for taking the time to post. It’s lifted the level of debate

Jeff Masters, over at the ‘Weather Underground’ (apparently a proud member of the Baader-Meinhof wing of Meteorlogy) is obsesssing about his “worst global warming” fear: Michigan is becoming like Ohio!

Corrected, thank you.
Where can you get a daily chart of the PNA index? Also is Weather Underground into the Liberal propaganda on Global Warming? Would it be wise to register in order to argue against Global Warming or do they ban people who don’t tow the party line?

This can be found on the WUWT Atmospheric Oscillation Reference Page

Yes.
Would it be wise to register in order to argue against Global Warming or do they ban people who don’t tow the party line?
Not sure, but it is always worth a try. If one is polite and factual it is less likely that you will be moderated out.
Romney ought to not talk to stephanopolis. That man is in really like with 0bama, literally! when he interviews him he blushes._Romney needs for getting tough instead of phase down. He experienced a presidential moment, when he permit 0bama have it right after the killing of your Ambassedor. Dont allow up on that..
