According to a graph published on the NASA Earth Observatory site, Arctic temperatures were warmer in 1930′s than at the end of the 20th century.
In addition, the graph shows the Arctic warmed ~1.6C over the 19 year period from ~1918-1937 at a rate of 0.84C/decade, 75% faster than the 0.48C/decade from 1980-2000. Thus, alarmist claims that recent Arctic warming is unprecedented or accelerating are bogus.
Proof positive that CO2 is really an insulator then. (/half s)
Data that contradicts the Holy Doctrine? How in H*ll did THAT get there? If we retract it, that will only draw that much more attention to it, so we’ll just have to leave it there and keep our mouths shut about it.
