Sadly, the attempts by Josh Willis to make these necessary corrections have already been misinterpreted in some sectors.
Thank you for your reference to that article.
Would you trust any "scientific" conclusions about global warming based on that article?
The problem is that the article is not proof of the pudding that global warming is real, in my opinion, if that is what you are suggesting. In fact, the article is arguably an apology that the computer models that are being used to study global temperatures are still crude, but slowly improving (ha ha).
It remains that the politically correct global warming alarmism that the MSM was shoving down everybody's throats awhile back is not justified, in my opinion, by politically correct interpretations of crude computer models. After all, computerized earth / weather models still can't be trusted to warn about things like the relatively recent Indonesian tsunami or the blizzard that closed Denver International Airport a few years back.
Sadly, the attempts by Josh Willis to make these necessary corrections have already been misinterpreted in some sectors.
And speaking of misinterpreting things, you're sidestepping the reality that Mr. Willis and other scientists probably continue to do their share of head-scratching with respect to interpreting crude, computerized global temperature models.
