Where Lies the Younger Dryas Smoking Gun?
Guest Post by Dan Johnston I have been following the proposed collision theory for the onset of the Younger Dryas for a number of years with considerable interest as it explains so much in a relatively straightforward fashion, if true. … Continue reading
New NSF paleo research claiming Arctic was warmer fails to take major ocean circulation changes 3 million years ago into account
I covered this story earlier today, and it was presented much differently in that press release. This press release takes a different tack. IMHO, it looks like a big “ooops” from the National Science Foundation. See what I found after … Continue reading
The Stokes-Kaufman contamination protocol – a ‘sticky’ wicket
Over at Climate Audit, Steve McIntyre has found yet another unexplainable inclusion of a hockey stick shaped proxy in the PAGES2K paper. What is most interesting about it is that when you look at the proxy plot panel, it reminds … Continue reading

A Quick Comment about the PAGES Continental Temperature Reconstructions
Normally, I don’t bother to discuss paleoclimatological reconstructions. The reason: most try, some through questionable methods, to illustrate that the recent warming is unusual and could only be explained by the increased emissions of manmade greenhouse gases. And that’s the … Continue reading

Yet another ‘unprecedented’ hot times tree ring reconstruction
From The Earth Institute at Columbia University comes another tree ring hockey stick. I have to laugh though at the choice of graphic for the press release, which shows a weather event (Euro heat wave) in 2003, rather than showing … Continue reading

Gergis made to order IPCC zombie climate science
Steve McIntyre points out how climate science errors return from the dead as zombies: PAGES2K, Gergis and Made-for-IPCC Journal Articles March 15, 2013 was the IPCC deadline for use in AR5 and predictably a wave of articles have been accepted. The … Continue reading

Another proxy study with an ‘unprecedented’ temperature claim
UPDATE: McIntyre discovers a serious flaw right away, more upside down Mann world – he writes: In keeping with the total and complete stubbornness of the paleoclimate community, they use the most famous series of Mann et al 2008: the … Continue reading

Quote of the week – ‘bad eggs’ in the Marcott et al non-stick omelete recipe
This is a scathing and revealing comment from another scientist regarding the Marcott et al affair. The context of it all has an odor of hydrogen sulfide about it.

Where’s the hockey stick? The ‘Marcott 9′ show no warming past 1950

The PR is in: the ‘may haves’ have it at NSF
From the National Science Foundation, another bit of Speculative Science™ note the caveat in bold, which is all they need for a headline that screams certainty: This sudden release of gases into the atmosphere may have created intense global warming, … Continue reading

Nitrogen as pollutant and lifegiver

McIntyre finds the Marcott ‘trick’ – How long before Science has to retract Marcott et al?
Steve McIntyre has made what I can only describe as a stunning discovery as to why there is a sharp uptick in the main Marcott et al graph being touted by the media from its publication in Science. It seems … Continue reading

Tick, tick, tick – how long will the new Marcott et al hockey stick survive?
Steve McIntyre writes of the curious uptick in the 20th century, which doesn’t seem to be rooted in reality, or to have been in Marcott’s PhD thesis: While one expects a difference between NHX and SHX in the Holocene, the … Continue reading
