- The rounded maps interpolate red through vast regions where there is no data - like most of Canada and the arctic. There is not a single data point shown in the arctic regions of Canada, yet the rounded map paints a broad brush of red across those regions.
- The rounding algorithms push all of the temperature regions upwards. Note the graph of the raw (250km) data shows average temperatures below normal for most of the southern hemisphere
- The map projections greatly exaggerate the size of polar regions and give the appearance of large areas of warmth, which are in fact much smaller than they appear.
Figure 1. Raw data rounded to 250km
Figure 2. Most of the area 0-60 south latitude shows below normal temperatures.
Figure 3. GISS rounded data to 1200km. There are vast areas of red which have no data points to back them up. The impression from this map is that July, 2007 was very hot, yet as you can see from the raw data above in figure 1, that was not the case in most places. Most of Antarctica appears bright red, yet this is based on a single location at the south pole where the temperature averaged colder than 65 below zero Farenheit. The Antarctic penninsula was about eight degrees below normal, but that is missing from this map. See figure 1.
Figure 5 shows the rounding errors. Blue regions are latitudes where temperatures were rounded up, and brown regions are rounded down. There is clearly a much greater region of rounded up temperatures than rounded down. Maybe by a factor of 10x.

NOAA SST animation is overlayed with NASA Modis fire data. Note how sea ice regions of Siberia near gas flares (80E) and burning forests (130E) are showing large amounts of melting. Could this be due to soot darkening the ice and making it melt faster?

Disclaimer - any similarity to more evolved humans is completely coincidental.
Lucy, the Global Warming pin-up girl, is clearly distraught from the disappearance of the glaciers. Either that or she is just chewing on her finger.

Buenos Aires has been averaging about five degrees below normal for the past three months, and had their first snowfall in 90 years.

To generate the plots yourself - go to http://data.giss.nasa.gov/gistemp/maps/
Below are the same plots with only anomalies greater than 0.5 degrees shown. Tough seeing any indication that the earth is warming, and this data is directly from Dr. James Hansen's web site. It might also be noted that the data only goes through 2006. The large warm bands in the Atlantic and Pacific have since disappeared, so next year's plot will be even more damning to AGW theory.

- The base period starts at 1971, which is a temperature minima. In the 1970s climatologists were warning of an impending ice age, due to rapidly cooling temperatures.
- The sensitivity is too high. The data set is not large enough to make meaningful comparisons within 0.5 degrees.
The maps below correct two of the three of the issues described above. They are equal area projections, and only temperatures which deviate by one degree or greater are shown. As you can see, ocean temperatures are generally close to normal and areas which deviate above and below the norm are about equal in size. Quite a different view of the world from what global warming alarmists would have you believe.
