I did, and was met by some real snobbery that what I posted had nothing to do with the topic, even though it was a notable (to the anti climate changers anyway) scientist attacking another climate change scientist. There seems to be a lot of big jabs at the credibility of some climate change scientists, so I thought it was worth posting.

It wasn't me that took it down that road, it was macfury.

End of story. I was happy to keep it to the topic I posted, about two 'climate change scientists'.

I read all that already. I get it. So, again, why keep chipping? Is it your intention to close the thread? And that will be the last I post on the subject as it is off topic.

I'm not chipping sinc. I've only responded to people's posts directed to me.

I don't think we need to go down here, once again.

Alright, back in Dec in GHG2 I posted about Ryan O’Donnell's submission to Journal of Climate refuting the Hockey Team's Eric Steig & his paper in Nature about Antarctic warming.

What the debate boiled down to was the use of Antarctic Peninsular & cherry picked Western Antarctica temperature stations data & what effect they had on reconstructions for temps in Western Antarctica & the Ross Ice Shelf.

O'Donnell questioned the methodology Steig used in his paper & substituted a version which gave significantly different results. There has since been some back & forth on the issue.

O'Donnell recently gave an explanation defending his methodology which was very math intensive. Since then he has come out with a short & very informative series of illustrations which summarize, in a nutshell, his defense.

Quote:
Please note how Eric’s reconstruction responds quite well to changes in the Peninsula . . . except it teleconnects them to the Ross Ice Shelf and the south pole.

Please also note how Eric’s reconstruction does not respond at all to changes in the only two West Antarctic land stations they used: Russkaya and Byrd (the response is even less if only the manned Byrd station is used).

Anything that he “got right” . . . as I said before . . . was by accident.
As I read on my morning blogroll today:

Still in denial about the global extent of the Medieval Warm (and Dry!) Period?

Here is a summary of another paper submitted to Geology with the following observations:

Quote:
According to the authors, they say their data indicate that "the special feature of this period in climate history is the distinct and persistent drought, from the early ninth century AD to the early thirteenth century AD," which interval "precisely overlaps the period commonly referred to as the MCA, due to its geographically widespread climatic anomalies both in temperature and moisture." In addition, they report that "the reconstruction also agrees well with the general picture of wetter conditions prevailing during the cool periods of the LIA (here, AD 1220-1650) and the DACP (here, AD 720-930)."

In discussing their findings, the three Finnish scientists note that "the global medieval drought that we found occurred in striking temporal synchrony with the multicentennial droughts previously described for North America (Stine, 1994; Cook et al., 2004, 2007), eastern South America (Stine, 1994; Rein et al., 2004), and equatorial East Africa (Verschuren et al., 2000; Russell and Johnson, 2005, 2007; Stager et al., 2005) between AD 900 and 1300." Noting further that "the global evidence argues for a common force behind the hydrological component of the MCA," they report that "previous studies have associated coeval megadroughts during the MCA in various parts of the globe with either solar forcing (Verschuren et al., 2000; Stager et al., 2005) or the ENSO (Cook et al., 2004, 2007; Rein et al., 2004; Herweijer et al., 2006, 2007; Graham et al., 2007, Seager et al., 2007)," stating that "the evidence so far points to the medieval solar activity maximum (AD 1100-1250), because it is observed in the Δ14C and 10Be series recovered from the chemistry of tree rings and ice cores, respectively (Solanki et al., 2004)."

And so the evidence continues to mount for a global and solar-induced Medieval Warm (and Dry!) Period, which likely eclipsed (in both categories) what the world has so far experienced during the Current Warm Period.
Bold mine.

Here's a cogent statement on the current state of global warming science by Federal EPA Administrator Lisa Jackson during testimony before the U.S. House Energy and Commerce’s Subcommittee on Energy and Power:

Quote:
"Our best scientists in this country have reached a consensus and it is unequivocal that the science is clear that 'man' made emissions or air pollution and global warming gases."

Unprecedented warming! Never before seen glacial melting! Oh, the horror!

I bring you this:

Quote:
The Danish chronicle states that a strong wind from the north-west carried to Iceland a large quantity of ice, laden with a number of bears and much wood.
and this:

Quote:
The Greenland whalers...found that the same thing had taken place on an extraordinary scale. No less than 18,000 square miles of ice had broken loose from the anchorage of centuries, and came plunging and whirling south and west, filling the bays and creeks of Iceland, wandering even to Labrador & Newfoundland, and disappearing in the Gulf Stream.
Date the second? 1816.

Date the first? 1271. That's twelve-seventy-one...

Along the same vein...

Quote:
The Arctic seems to be warming up. Reports from fishermen, seal hunters, and explorers who sail the seas about Spitsbergen and the eastern Arctic, all point to a radical change in climatic conditions, and hitherto unheard-of high temperatures in that part of the earth's surface.
and

Quote:
The oceanographic observations have, however, been even more interesting. Ice conditions were exceptional. In fact, so little ice has never before been noted. The expedition all but established a record, sailing as far north as 81˚29' in ice-free water. This is the farthest north ever reached with modern oceanographic apparatus.
and

Quote:
There were few seal in Spitsbergen waters this year, the catch being far under the average. This, however, did not surpnse the captain. He pointed out that formerly the waters about Spitsbergen held an even summer temperature of about 3° Celsius; this year recorded temperatures up to 15°, and last winter the ocean did not freeze over even on the north coast of Spitsbergen.

With the disappearance of white fish and seal has come other life in these waters. This year herring in great shoals were found along the west coast of Spitsbergen, all the way from the fry to the veritable great herring. Shoals of smelt were also met with.
Observations made in 1922.

Natural cycles, people.

Gosh FeXL, I don't remember seeing that happen. The world began in 1970 didn't it?

According to some of these sorry SOB's, yes.

Meanwhile, science carries on...
