Newsweek is about as credible as the National Enquirer, blatham. I dropped my subscription years ago. I read the article, but the photo of mudcracks where water had stood somewhere is a tipoff as to the scientific qualifications of the article, which are virtually nil. All political, which is nothing new.
Here are a couple of pertinent links. First author Christopher Horner's comments on youtube:

Also, will it take a bunch of bloggers to keep NASA honest? Not only does this article discuss 1934 being the warmest year in the U.S. instead of 1998 as commonly reported, but it also discusses the heat island effect which has been downplayed, but obviously is a significant factor. People are now beginning to document the erroneous conditions that cause erroneous temperature recordings at many weather stations. Yes, the internet is truly a beautiful thing in regard to some issues. Information cannot be doctored and boilerhoused without somebody figuring it out.

Last but not least, when this whole global warming issue arose many years ago, my first thought was - do we really have enough reliable data with similar conditions from enough places around the world that can even tell us what the globe is doing in fractions of a degree? After all, only one of my questions figured the globe is not going to uniformly heat up or cool down, but there will be shifts and concentrations of change one way or the other, or both, in regions of the world, as orchestrated by the shifts and paths of weather systems, as relates to the ocean and many other factors. Then as this whole thing gathered steam, I kind of relented to the idea that perhaps the scientists must have a fair handle on it to be roughly correct about the temperature trends, although I suspected more land use influence than generally considered.
Now, I think I am going to back up, as I may resort to my first gut reactions about temperature records. Enough good temperature records from around the world that have consistently been recorded accurately under similar conditions are I think a big stretch. And I read that the so-called scientists interpolate temperatures for desert areas, per elevation from known stations, after all - we don't really have good spatial coverage of temperatures around the globe now, let alone decades ago. Perhaps attempts to figure this all out might be okay, but to make grand conclusions as to trends of less than 1 degree are not what I would call very statistically accurate or significant.
If we resort to looking at a weather station with one of the longest records, and with similar conditions for the duration, look at Mt. Armagh in Northern Ireland, and the following graph shows temperatures roughly the same in the year 2000 as it was in 1950, as well as around 1850, certainly within only a very small fraction of a degree C, and the current trend is not remarkably up, but rather on a bit of a plateau and showing no distinct trend as to which way it is headed.
To be accurate, there is no doubt that cycles exist, and that the temperatures are fluctuating, but so is precipitation and cloud cover, and everything else, little of which is very well documented at all, and all of which contribute to the scenario.
My suspicions are confirmed by many readings and observations, one being this site:

The sky is falling crowd, along with Al Gore can keep running off into the sunset, in total panic, but I am going to continue to harbor healthy skepticism, as so far the data does not appear to justify the former. We have not even established a very sound global system of recording of temperature and other weather patterns that have a sufficiently historical record to make grand pronouncements in fractions of a degree, let alone establish what is causing it.
