The EPA has this graph on their website, based on the NCDC Climate Extremes Index
High and Low Temperatures | Climate Change | US EPA
It shows that the area of the US with hot daily summer temperatures is at record levels.
The graph is completely fraudulent. In fact it is inverted. Prior to 1960, the area of the US which reached 100 degrees during summer was quite a bit higher, and in 1936 seventy-five percent of stations reached 100 degrees. The percentage of the US reaching 100 degrees every year is much lower now, with 2014 close to a record low.
The EPA graph shows 2012 as the hottest, when in fact it wasn’t even in the top ten. They show 1936 at 50%, when in fact it was 75%.
Next is the minimum temperature graph – again in sharp disagreement with the EPA graph.
This metric is not affected by TOBS or homogenization. Apparently the good people at NCDC are simply fabricating numbers, because I used their thermometer data in this analysis.
In the 19th century, about 30% of stations in the Midwest would reach 100 degrees every year. Now that figure is less than 10%. In 1936, almost every station in the Midwest reached 100 degrees.
Unless we take immediate action and move back into caves, the Arctic will be ice-free in the blink of an eye.
You can catch Prof McPherson at an event co-organised by AUT’s School of Social Sciences and Public Policy and the Pacific Media Centre in Auckland on October 22 at 5.30pm.
Tonight on the Paul Henry Show, he explains that due to the arrogance of humans, the damage done is too far along and now irreversible.
Now, the only way to help planet Earth is to “terminate industrial civilisation“.
Climate change now ‘irreversible’ Prof McPherson | TVShows | 3 News
It has been suggested that the lack of a tropospheric hotspot (if there is such a lack) is mostly due to errors in the surface temperature datasets, which are (in this story line) suspected of being biased in the direction of too much warming. This seems unlikely. Clearly, the above spread in results for different upper air datasets reveals considerable structural uncertainty (Thorne et al, 2005) for the upper air data, and the error bar on the RSS trend values is much larger than the error bar for the HadCRUT4 value. Also, the various surface datasets are much more similar to each other. To show this, I redo the analysis in Figure 1 using a different surface dataset constructed by NOAA (GHCN-ERSST). The final trend ratios are almost identical to those found using HADCRUT4, and the conclusions reached are unchanged.

Carl is a smart guy, but he let his preconceived notions turn logic on its ear.
The surface data sets are crap, and they change constantly. The past doesn’t look anything like it did 40 years ago. And the current data sets all use the same tortured data – so of course they look the same.
Garbage in – garbage out.
