There isn't an educated person on the subject who claims CO2 doesn't cause warming and that we haven't warmed.  Obviously less ice formation on the northern shelf is going to affect weather patterns, but there's no proof of adverse effects as a result.  And frankly, I don't have a lot of confidence in the false sense of precision with respect to "reconstructions".  A few tenths of a degree makes a huge difference in conclusions. 

I have access to the Nature database. I just copied the entire article to you in a private message.

The article argues that over the last 2,000 years ("the pre-industrial common era") instances of warming or cooling have been regional; the last two centuries differ in that they show a consistent temperature rise across the globe, in all regions--i.e., the warming has been "globally coherent," occurring everywhere.  People arguing that "there has been warming/cooling in the recent past" (e.g., the "little Ice Age") generally do not take this coherence into account. That's the argument in a nutshell. The source notes also give a sense how the argument of these 5 scientists has developed within and rests upon accumulated research on "global coherence."

I have forwarded your post to the residents of Shishmaref, Alaska, who will take comfort in the knowledge that there is no proof that less ice formation has "adverse effects". If only they'd known this before they had to move their entire village.
