From the story:  The Australian’s overheated time warp misses half of 2010 which had a NOAA press release in it below the fold, Dr. Richard Keen weighs in and does a spot check of the data from his own NOAA station (he’s an official observer).

And if you find this map hard to look at, you aren’t alone in seeing spots.

Lawrimore’s comment…

“Heavy snow, like the record snows that crippled Baltimore and Washington last winter, is likely to increase because storms are moving north. Also, the Great Lakes aren’t freezing as early or as much. “As cold outbreaks occur, cold air goes over the Great Lakes, picks up moisture and dumps on the Northeast,” he says.”

…shows a complete lack of understanding of weather (which makes up climate).   

East coast snows are caused by lows off the coast, and if the storms move north, Baltimore, Philadelphia, NYC et al. find themselves in the warm sectors of the lows, and enjoy warm southerly winds and rain.

Furthermore, during the snow storms, the winds are from the northeast bringing moisture from the Atlantic (hence the name “nor’easter” for these storms); very little of the moisture comes from the Great Lakes.  One of Philadelphia’s snowiest winters was 1978-79, when the Lakes were all but frozen over.  Along the east coast, a region that averages very near freezing during the winter, the limiting factor for snow storms is not moisture, but temperature.  Most storms are rain.
Now, the spot check.
NOAA’s calculation of the global temperature is based on their analysis of departures at 2000 or so grid points.  One of those points included my weather station at Coal Creek Canyon, Colorado, a location with no UHI or other troublesome influences.  The NOAA map of June anomalies for the US, based on an unknown selection of stations, has Coal Creek sitting on the +4F contour.

The Coal Creek record is long enough to calculate 30-year normals, and June 2010 comes in at +1.0F above normal.

That’s 3 degrees less than the NOAA estimate for the same location, which is the difference between June being in the top 3 or being in the middle third.  Now, this is simply a spot check of one of NOAA’s 2000 grid points, but it leads to the question of how far off are the other grid points?
