How can they not see that this data point is way out of bounds? Or, maybe the real data leaked out! But, for what purpose? Why are THEY(whomever they could be) doing this? My pet theory is that aliens who do not tolerate CO2 want to take over the Earth, but they must make it habitable for their armies first! This could be the only logical explanation that I can come up with. I’m pretty sure that Michael Mann is one of their forward guard who has been surgically altered to breath CO2 without too many ill effects. One can tell from looking at him though to realize that they weren’t totally successful. Mann’s objective is to convince that we humans can control our climate by adjusting CO2 levels. The tree ring and data ideas splicing were his alone. sarc/off

It looks like someone let out some real Antarctic values for that last point instead of the Quality Controlled version.
Obviously a mistake
Obviously … yet … NSIDC’s standard is 15% ice coverage. There is a lot of extra white.

Sorry about the typos but I was laughing too hard picturing Mikey having a meltdown when he loses the law suit.
