[i]Crap! Ice sheets growing? Not according to NASA they're not, ice-sheet thickening is consistent with global warming...
Right - Antartica is warming is it? Is that based on multiple accurate temperature readings? No? Just one? And it's likely inaccurate due to development at the particular science station?
http://wattsupwiththat.com/2009/12/13/f ... ghcn-data/This, like most other purported evidence, has been found wanting. Even Pachauri and his chums at the IPCC have admitted Antartica (and Greenland) is going nowhere fast - and would require, so we're as scientific about this as we can be, temperatures above our current rate of 2C (3.5 F) for many thousands of years. Whilst I completely agree the climate is changing, it always has, what we're now seeing is a reduction in temperatures if anything - painful for you I'm sure.
Nobody disputes that the medieval warming period happened
Actually, they do, and many charts suggesting violent rises in warming have removed prior warm periods. Yes we warmed, and yes, we're now cooling - thank you very much.
but it was not as warm as it is today
Again, inaccurate (and again data has been cherry picked - see news out of Russia just earlier this week). Certainly temperatures were much higher. Have a look here:
http://pages.science-skeptical.de/MWP/M ... eriod.html - you might like to click the charts, they go off to real scientific papers, all available for peer-review.
tree-ring records have proven this.
Are you referring to the 14 (or might have been 16) samples which went into the original hockey stick chart? Wow, that's a sizeable sample isn't it - even without the fudging which went on...
Back to the drawing board for you methinks.
Not really, unfortunately I'm an analyst that specialises in the creation of detailed, functional, models from ridiculously large datasets - I even have a company which offers this service to other people. I've taken the time to review the datasets, the graphs produced by vested scientists, and the writing is on the wall - politicians and some of the public have been duped - the only issue we're going to face in the coming years is a plunge in global temperatures (which we're not ready for), a theory based on real evidence and all dreamt up by that wonderful organisation known to you as CERN.
The fact CO2 has been proven to
follow (not cause) temperature change pretty much debunks anything you can say. Would you like to borrow my drawing board...?
