I must have had 20 tips and notes/contacts over the past 24 hours like this one:
New temperature proxy discovered
An article (http://www.dailymail.co.uk/sciencetech/article-2120512/Global-warming-Earth-heated-medieval-times-human-CO2-emissions.html) in the Mail Online describes a paper (http://www.sciencedirect.com/science/article/pii/S0012821X12000659) detailing a new temperature proxy that indicates that the Medieval Warm Period was global, not merely regional.
WUWT had the story first, 5 days ago on March 22nd. Somehow a lot of people missed it, so I’m linking to it again. Read it here: More evidence the Medieval Warm Period was global
And I have more graphs and information from the actual paper than the Daily Mail has.
UPDATE: 3/30/12 Since a number of commenters that are getting bent out of shape over the issue can’t apparently be bothered to read the paper, and since the authors at Syracuse themselves are under pressure because the alarmosphere has gone ballistic over the possibility that Mike Mann’s “there is no MWP much less global” gospel might be challenged, I offer readers this passage from the actual paper:
The resolution of our record is insufficient to constrain
the ages of these climatic oscillations in the Southern
hemisphere relative to their expression in the Northern hemisphere, but our ikaite record builds the case that the oscillations of the MWP and LIA are global in their extent and their impact reaches as far South as the Antarctic Peninsula, while prior studies in the AP region
have had mixed results.
I realize that because the authors chose a really poor place to publish it, in Elsevier, which is being boycotted worldwide for their draconian policies on scientific publishing, that many people haven’t read the actual paper, but instead rely on others to interpret it for them, sparing them the effort of having to think or investigate for themselves. Of course the same sorts of people that claim my headline is wrong won’t believe the passage I’ve cited above, therefore I’m reproducing page 114 of the journal Earth and Planetary Science Letters 325–326 (2012) with the relevant passage highlighted:
Some media (The Daily Mail for example) have oversold the conclusions of the paper, and thus this is why the authors have issued a statement. Based on their words above in their own paper, I stand by my headline. Note that the authors at Syracuse have NOT asked me to change my headline nor any part of my post on the issue. – Anthony
