Comments on: Mann 2008: Impact of the Missing Data http://climateaudit.org/2008/09/15/mann-2008-impact-of-the-missing-data/ by Steve McIntyre Wed, 19 Jun 2013 17:55:02 +0000 hourly 1 http://wordpress.com/ By: Jeff Id http://climateaudit.org/2008/09/15/mann-2008-impact-of-the-missing-data/#comment-161823 Thu, 18 Sep 2008 15:44:50 +0000 http://www.climateaudit.org/?p=3637#comment-161823 This is kind of a dead thread but I don’t want it to be off topic.

I think this is my best work so far. There are some monster problems in the Mann08 data.

Oh, I would have thought the new paper was different and improved.
But really, it is just “Same stick, new wrapping” then :(

Please ignore my last post (or even delete it), as I had misunderstood how to use the radiative transfer model. One simply needs to increase the “Ground T offset, C” (by say 1C), to bring Iout back to 258.799. i.e. “rebalancing the OLR” (Outgoing Longwave Radiation).

see this BBC content … However there are methods to do so(?), which I of
course not endorse, described at YouTube…Firefox 3 seems to help?!

I rate it as bad a “Swindle” which I also didn’t think much of. The Hockey Stick is there in all it’s glory with some short interview snippets from Mann. Iain Stewart portrays the HS as proven beyond much doubt, he doesn’t appear to have researched the controversy in great detail.

I think you’ll find it interesting.

That should be real interesting.

Thanks for the link to a real radiative transfer model! I will have a play… But just in case any other non-climate-scientist here wants to have a go, you missed one vital piece of info: A 1C rise in temperature is caused by a 3.3 W/m2 drop in the Earth’s radiative output (Iout). Thus in your first example, increasing the CO2 from 375 to 820 caused Iout to drop from 255.565 to 258.799 (i.e. drops by 3.234 which is approx 3.3).

“You don’t understand, Stevie Mac never gets that Hockey-Stick. The Stick is perfect for him;
it’ll make him a big star. And I’m gonna run him out of the business, and let me tell you why.
Stevie Mac ruined one of the Team’s most valuable proteges. For five years
we had her under training. Singing lessons; acting lessons, dancing lessons. I spent hundreds
of thousands of dollars on her. I was gonna make her a big star! And let me be even more
frank, just to show you that I’m not a hard-hearted man, and it’s not all dollars and cents.
She was beautiful; she was young, she was innocent. She had the greatest Bristlecone Core
Sample I ever had seen, and I had seen’em all over a very small portion of North America! And
then Stevie Mac comes along with his maple syrup voice, and Canuck charm. And she runs off.
She threw it all away just to make me look ridiculous! And a man in my position can’t afford to
be made to look ridiculous! Now you get the hell outta here!”
