ttbn,
I had intended to say nothing else on this topic. However, your maligning of Michael Mann should not be allowed to fester. He is a renowned climate scientist whose “hockey stick” research result has been lauded. His work has been well and truly verified. You can read about reviews that verified his wwork.

If you wish to comment, do so from a base of knowledge and understanding. Otherwise, please shutup!!

Tony Mann's work is shoddy and basially fraudulent. That he continues to have a reputation anyone would defend is amazing. The statistical techniques he used were shown to have been wrongly applied - check out Wegman's report. And that was before anyone found out that he actually jettisoned the proxy data when they didn't show what he wanted and substituted a thermometer record for them. This is basically fraud. While he noted that he'd moved from proxies to instrumental he never said it was because at this point the proxies showed a decline in temperature. Which meant they were unreliable as proxies and should never have been used. This is why I call him Piltdown Mann.

We are indebted to McIntyre and McKitrick for their work in uncovering the problems with his work, and it is a good demonstration of how citizen science works. McKitrick has a good summary of the points here http://www.rossmckitrick.com/uploads/4/8/0/8/4808045/hockey-stick-retrospective.pdf

Just disgraceful that you would leave your post here, obviously trying to confuse someone who is following this thread.

Talk about pot kettle black Tony153, Mann's hockey stick has been so completely discredited, that he should be too ashamed to show his face in public. What planet have you been on the last 15 years.

Prey tell, are you a gravy train rider, or just a fellow traveller.

I think black would be white to Tony 153 who probably still believes in Father Christmas.

With all the technologies available for conferencing these days, the likes of Mann still like the junkets, paid for by someone else, including big emission flights from one side of the world to the other. That other liar, Gore, is also a big personal polluter and user of recourses. 'Hypocritical' doesn't even begin describe these confidence tricksters.

Dear GrahamY,

If you are reluctant to accept the conclusions of the National Snow and Ice Data Center (backed up by robust and publicly available data) that there is a measurable increase in the area of the Greenland Ice sheet which is melting, then I'm interested to know what evidence it would take to convince you?
