New NSF paleo research claiming Arctic was warmer fails to take major ocean circulation changes 3 million years ago into account

Posted on May 9, 2013 by

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 →

A Quick Comment about the PAGES Continental Temperature Reconstructions

Posted on April 23, 2013 by

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

Posted on April 22, 2013 by

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 →

Quote of the week – ‘bad eggs’ in the Marcott et al non-stick omelete recipe

Posted on March 31, 2013 by

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.

The PR is in: the ‘may haves’ have it at NSF

Posted on March 22, 2013 by

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

Posted on March 21, 2013 by

From Kansas State University, dueling statements, which I’ve highlighted in bold. Its the same sort of nonsense argument we here for Carbon Dioxide, that while essential for all life on the planet, it is also a pollutant. I see a … Continue reading →

Shades of upside down Tiljander. McIntyre is delving further into the Marcott proxy issue and it looks almost certain now there’s a statistical processing error (selection bias). Steve McIntyre writes: In the graphic below, I’ve plotted Marcott’s NHX reconstruction against … Continue reading →

Tick, tick, tick – how long will the new Marcott et al hockey stick survive?

Posted on March 15, 2013 by

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 →
